How to Fix PFN_LIST_CORRUPT Error on Windows

If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help.

Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

  • Tap the Win + I keys to open the Settings panel.
  • Then go to Update & Security > Troubleshoot.
  • From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

  • On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
  • Next, click on Disk Management on the left side panel.
  • From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

  • Wait for the process to be completed and then restart your computer.

Option 4 – Update the Device drivers

Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.

  • Tap the Win + R keys to launch Run.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.

  • Tap the Ctrl + Shift + Esc keys to open the Task Manager.
  • Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
  • Then go to the Startup tab and select Microsoft OneDrive and then click Disable.

Malware Guide: How to Remove Webguard

What is Webguard?

Developed by Interesting Solutions, Webguard is a tool supposedly used for tracking those online who’ve developed a habit of tracking you. The application would provide logical analysis into a user’s website history, providing insight on what websites you’ve visited and also how persons are able to track your every move while browsing. While Webguard is unable to dispose of who specifically is tracking your computer usage, they’re able to determine what computer installed tracking codes or cookies on your computer system. In this case, it’s then left up to the user’s discretion to determine who they want to allow or block from tracking their online use.  Overall, this application allows the user some measure of freedom and control over their online experience. Like any other application, however, which has landed themselves a spot on Virus Total, Web guard has hidden agendas. At a distance, Webguard installs a service for Windows but later distributes advertisements. Technical details about Webguard include:
Product Version: 1.0.0.0 Original File Name: crss.exe Entry Point:  0x000C5AAE

Assessment of Webguard Potentially Unwanted Program

While Webguard claims to track your computer usage, information reported by the application isn’t sufficient for the common computer user. This brings us back to the ulterior motive or principal objective of developing Webguard – to advertise and generate revenue from clicks made by users on Ads displayed on Internet Browsers – namely Chrome, Internet Explorer and Firefox. Why should a computer user remove Webguard? Simply, it compromises one's Internet privacy and security and it keeps abreast of your Internet history. If you’re online for an extended period, you’ll see what Webguard does. While the publishers behind the application did not alert users to the use of web beacons, cookies for tracking, and other related tracking technology, that’s not why Webguard is considered unwanted. The program is potentially unwanted because of the unpredictable advertisements it displays. Not all sites are trusted and so it’s difficult to determine, in some cases, what websites are legit for business.

Remove Webguard with Spyhunter

In most cases, at least from what I’ve seen, Webguard is installed as a single application. After it was installed for this assessment, it could be found in ‘All Programs”. This meant that one could manually delete the application from their computer system (see manual steps below). However, is that really sufficient to completely rid your PC of Webguard’s blueprints? While you might opt to remove Webguard manually – maybe because it’s more economical – an automated process is able to completely eradicate hidden threats from Webguard. In comparison to manually removing Webguard, Spyhunter penetrates your computer system for all infections. In most cases, nasty threats are unable to be removed manually. Additionally, Spyhunter not only removes installed threats, but it detects incoming ones – hence, acting as a preventative tool. Furthermore, Spyhunter detects cookies placed on your computer by Webguard. These are all undetectable threats and so an automated tool, as Spyhunter, should be used to remove Spyhunter effectively from your computer.

Manual Steps for Removal of Webguard

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:
  • Step 1: Locate the CONTROL PANEL on your computer using the SEARCH option.
  • Step 2: Once the search box appears , input 'CONTROL PANEL'.
  • Step 3: The Control Panel option will then appear. From the menu, choose the "Programs" option.
  • Step 4: Another menu will appear. Select "All Programs and Features".
  • Step 5: From the 'Programs list', search for the Webguard application.
  • Step 6: Right-click on Webguard when it's found.
  • Step 7:  Choose the "Uninstall" option.
  • Step 8:  Follow the uninstall wizard instructions until the Webguard application is fully removed.

0x800703EE when copying to external storage
If you are trying to copy or move files to and from your external storage device but you suddenly encounter the error 0x800703EE, then you’ve come to the right place as this post will guide you on how you can fix this error in your Windows 10 computer. This kind of error when copying files may be accompanied by an error message that says, “The volume for a file has been externally altered so that the opened file is no longer valid”. This error prevents you from copying or moving the files to and from the external storage device. This kind of issue might be caused by a service that belongs to a backup program that could be blocking the operation or a conflict with your third-party antivirus program. In addition, the error could also be due to corrupted or outdated USB drivers or it could be caused by a disabled Windows Backup and Volume Shadow copy service. It is also possible that some system files are corrupted or that the drivers for the external device are also corrupted. Whatever the cause is, here are some options you need to check out to fix the error. Before you troubleshoot the error, you might want to try moving the files to another location on your local drive and remove the USB drive and insert it back again. After that, try to move or copy the file to the USB drive and see if it still throws an error. If it does, then you need to troubleshoot the problem further by following each one of the suggestions given below.

Option 1 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 2 – Try checking the Volume Shadow Copy and Windows Backup services

The next thing you can do to fix error 0x800703EE is to check the Volume Shadow Copy and Windows Backup service.
  • First, tap the Win + R keys to open the Run dialog box and type “services.msc” in the field, and hit Enter to open the Services Manager.
  • From there, look for the Volume Shadow Copy service and right-click on it, and then select Properties.
  • After that, make sure that its Startup type is set to Manual and that its status is “Started” so if it isn’t, you need to click on the Start button and then on the Apply and OK buttons to save the changes made.
  • Once done, look for the Windows Backup Service and repeat the same process you did with the Volume Shadow Copy service.
  • After you complete the steps, restart your computer and see if the error is now fixed.

Option 3 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • Now try to copy the files to your external storage device again and check if the error is now gone.

Option 4 – Try to run System File Checker or SFC scan

  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow and hit Enter.
  • Once done, restart your computer.

Option 5 – Try to delete the Filter drivers

Note that this option is only applicable if you see the error 0x800703EE accompanied with the “The volume for a file has been externally altered so that the opened file is no longer valid” error message. Before you start, create a System Restore Point first.
  • Open the Registry Editor and navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}
  • After that, select the “{4D36E965-E325-11CE-BFC1-08002BE10318}” key and check if you can find the “Upperfilters” and “Lowerfilters” value in the right pane. If you can find them, right-click on them and select Delete.
  • Once done, exit the Registry Editor and restart your computer.

Windows 11 Home edition account requirements
Windows 11 has been officially presented during Microsoft’s virtual event on June 24th. Since presentation internet has been pretty live and busy with a discussion about it, some discussions are positive, some not so much but that is expected and it happens always when a new product is presented. One of information that we have about Windows 11 is tied to the home edition of this OS, Windows 11 home edition will require an internet connection at setup, and a Microsoft account in order to be installed and used. Previous versions of Windows could be installed and used with local accounts but it seems Microsoft has abandoned that idea for its new OS. OS will be delivered mostly as updates or via internet download so internet and online requirement make sense but why it cannot use the local account and must have a Microsoft one is beyond me.

Fix Windows Update Error 0x80070BC9
As you know, every Windows Update is essential for every Windows operating system. They have to be regularly installed, especially since they include various security updates that are important to the system. However, there are times when Windows Update fails to execute properly and you get errors like the error code 0x80070BC9. When you encounter this particular Windows Update error, you will get the following error message on your screen:
“0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.”
This kind of Windows Update error is most likely caused by a newly installed problematic software, corrupted Windows Update files, or policies that restrict the behavior of the Windows Module Installer. The Windows Module Installer, also known as “WMIW” or “TiWorker.exe”, is the one that checks for new updates from the Windows server and installs them on your computer. This is why you need to make sure that you do not have any policies that control the start behavior of the Windows Module Installer since this service must not be hardened to any start value and should be managed by the operating system. To resolve the Windows Update error code 0x80070BC9, you can check out the options provided below.

Option 1 – Try checking the status of the Windows Modules Installer Worker Service

Since the Windows Update error code 0x80070BC9 has something to do with the Windows Module Installer Worker service, you need to check its status in the Service Manager. Refer to the following steps to do so.
  • In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “MSC” in the field and hit Enter to open the Services Manager.
  • After opening the Services Manager, look for the Windows Modules Installer Worker Service.
  • Once you found it, check its status and make sure that its Startup type is set to Manual.
  • Now click on the Start button and see if it fixes the Windows Update error.

Option 2 – Run the Windows Update Troubleshooter

You might want to run a built-in Windows Update troubleshooter to resolve the Windows Update error. It is one of the things you can check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run this troubleshooter, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try contacting the IT administrator to modify the group policies

You could also try to contact the IT administrator to have the group policies modified. This option is applicable for company-managed systems. As mentioned, one of the possible causes of the Windows Update error 0x80072EE2 is the policies that control the start behavior of the Windows Module Installer. Thus, you need to have them removed so that the Windows Module Installer Worker service is managed by the operating system itself. And since there could be many policies, it is highly advised that you contact your company’s IT administrator to get the job done for you.

Option 4 – Try to install the Windows Updates in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing Windows Update error code 0x80070BC9. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

0x8019019a when setting up Yahoo Mail
The error code 0X8019019A is shown when a user fails to add his Yahoo account to the Mail app due to the outdated or corrupt installation of the Mail app. Not using an App-specific but a normal Yahoo account password may also result in the error at hand. In this guide, we will show you how to effectively fix this error so you can set up Yahoo mail.
  1. Reboot PC

    Perform a restart of your system to rule out a temporary glitch in the system. Also, check if you can successfully access your email through a web browser using the same credentials as you are using with the Mail app. Additionally, make sure that no VPN or proxy server is being used to access the internet (VPN/proxy may work fine with the web version of Yahoo mail but may hinder the access through a mail client).
  2. Update Windows and the Mail App to the Latest Build

    If your system is not updated to the latest build it can create incompatibility between the OS modules. Updating the Windows and Mail app of your system to the latest build may solve the problem.
  3. Re-add the Yahoo Account to the Mail App

    The Yahoo account issue could be a result of a temporary glitch in the communication modules of the system. The glitch may get cleared if you remove and then re-add the Yahoo account to the Mail app.
  4. Reset the Mail App to the Defaults

    You may fail to add the Yahoo account to the Mail app if the installation of Mail itself is corrupt. In this scenario, resetting the Mail app to the defaults may solve the problem.
  5. Generate an App Password and Use it to Add the Yahoo Account to the Mail App

    Yahoo has implemented tons of security features to its accounts. One such feature is the use of app-specific passwords for less secure apps like the Mail app. If your Yahoo username or password is not working with the Mail app, then using the App-specific password may solve the problem.

Windows 11 new features and preview
Microsoft has presented its next version of their flagship product, Windows 11, and feelings are divided among users. Some users like it very much and eager to upgrade, some do not like the graphic overhaul it went through, but overall I think Microsoft has done a good job with it. Here in this article, we will discuss some of the new features which Windows brings to the table, well at least ones that were showed, I am sure there are plenty more which we will see once OS has been released.

New Start menu

Winodws 11 start menuOne of the first things that everyone saw when Microsoft has unveiled Windows 11 is its Start menu. Funny enough this is what has caused most of the divide among users, some find it interesting, and some do not like it. Truth is, it is different, and it is centered in the middle instead of the lower left part of the screen. It has been confirmed however that the Start menu can be moved to any part of the screen so if you want, you could place it on the lower left as it has always been. Live tiles do not longer exist in the Start menu, instead, we have styled simple icons.

Windows 11 Snap controls are great

Windows 11 snap controlsIf you have used the cascade option in previous Windows versions then it is most likely that you will like the new Snap controls. You can quickly snap windows side by side, or arrange them in sections on your desktop just by hovering over maximize button on the title bar.

Windows 11 File Explorer

Windows 11 file explorerFile explorer has gone through some visual and design changes, the ribbon on top has been completely removed and replaced with a header-like feature with a slick and clean design. The header contains a nice organized and designed single row of icons like cut, paste, copy, rename, delete, and new folder icons.

Settings app ovberhaul

Windows 11 settings appThe settings app also has gone through visual and design changes. It has a new design that is very visually appealing and navigation has been simplified and more organized. Finding the right and desired setting is much faster and clearer now.

Widget tab makes comeback in Windows 11

Windows 11 widgets barYes, widgets are back but not like you remember them. Instead of being all-time present at your desktop like once they used to be, now there is a button on the taskbar which brings the widget bar up that contains desired widgets. This way they are easily accessible and do not clutter desktops. So far we have weather, news, calendar, and stocks widget but we will see how development on these goes. I expect to have community-made widgets like in old days for all of our needs.

XBOX app

Windows 11 xbox appThe new Xbox app is now integrated into Windows 11, offering quick access to Xbox Game Pass games, the social parts of the Xbox network, and the Xbox store.

Security and TPM 2.0 in Windows 11

Windows 11As widely known by now Windows 11 will require you to have a TPM 2.0 module capable CPU in order to install it. This system requirement has caused a lot of controversies but essentially it seems that MS's goal is to protect your personal data by using this module. The upside of course is that your data will be protected much more than in previous Windows versions, the downside, of course, will be that you will need newer hardware to run OS on it. and that is essentially it, keep on tuned on more Windows 11 information and overall articles tied to PC and technology here at errortools.com

Fix ndis.sys failed BSOD error on Windows 10
NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in the proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices. The ndis.sys files are stored mostly in a driver folder at C:/Windows/System32/drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown. It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files, and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs in the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.

Option 1 – Try to update or reinstall the PC device driver

The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.
  • Tap the Win + R keys to launch Run.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • Restart your PC.

Option 2 – Rollback your Network drivers

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:
  • Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
  • Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
  • Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
  • Then select each one of them and double-click to open a new mini window.
  • After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
  • Now restart your computer to successfully apply the changes made.

Option 3 – Try running the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow and hit Enter.
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Try running the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.
  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
  • Wait for the process to be completed and then restart your computer.

Option 5 – Run the DISM Tool

What to do if CPU is not running at full speed
The speed at which the CPU runs varies depending on any Windows laptop or desktop. And in case you don’t know, the CPU does not run at full speed all the time as it depends on how the operating system distributes the load so it works accordingly. However, there are instances when it runs at full speed especially if your Windows 10 computer is on a heavy workload. But if you find that even when your computer is already on a heavy workload and the CPU is still not running at full speed, then you need to look into this situation. To verify that your CPU’s speed, you can use any CPU stress test tool. This kind of issue is common on laptops compared to desktop computers since laptop runs on battery. The Intel Processor on laptops uses the Speed Stepping Technology which means that when you are doing some small tasks on your laptop, the processor’s speed is reduced. On the other hand, if this happens when you are using a heavy application, it can be due to a low charge on the laptop’s battery. Thus, Windows will try its best to keep the computer running for as long as possible by reducing the CPU speed or processor. But there are times when you are ready to sacrifice battery to make sure that the work gets done on time. To achieve that, here are some options you can check out.

Option 1 – Try setting the processor state to the maximum in Power Options

  • Type “control” in the search box to view the classic Control Panel as well as the popular options.
  • Next, click on Power Options > Change plan settings > Change advanced power settings.
  • Then navigate to Processor power management > Maximum processor state.
  • Now select 100% when it is on Battery and Plugged in.
  • After that, expand the System cooling policy option and make sure to set it as Active to make sure that the battery won’t overheat.
  • Finally, apply the changes made to all the profiles of the power management and restart your computer. This will ensure that your CPU will run at maximum power at all times.

Option 2 – Try to update or disable the Intel Power Management driver

The next option you can try is to update or disable the Intel Power Management driver. The Intel-powered computers have dedicated software that controls CPU speed and Fan speed when it needs to save battery. You can try disabling it temporarily and check if there are any changes with the CPU fan speed.
  • First, restart your computer by holding the Shift key to boot your computer into Troubleshooting or Advanced mode.
  • Next, go to Troubleshoot > Advanced Options > Command Prompt.
  • Then change the directory to C:/Windows/System32/driver and then rename the file named “Intelppm” by entering the “ren intelppm.sys intelppm.sys.bak”.
  • Now restart your computer.
Note: If you were not able to find the drivers in C:/Windows/System32/driver, check if they are available under C:/Drivers/IntelPPM. After that, the CPU speed should change now with the Intel driver missing from the system. And in case you want to enable it, simply follow the same steps given above and rename the file again.

Option 3 – Try disabling the IPPM using the Command Line or Registry Editor

  • Command Prompt:
    • Tap the Win + R keys to open the Run dialog box and type “cmd” and tap Enter to open Command Prompt.
    • Next, type this command and hit Enter: sc config intelppm start= disabled
    • The “sc config” command you entered modifies the value of a service’s entries in the registry as well as in the Service Control Manager database.
  • Registry Editor:
    • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
    • Next, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesintelppm.
    • From there, double click on the intelppm and change the Start key value to
    • Now close the Registry Editor and reboot your computer.
Note: The steps given will make sure that the CPU will run at maximum power at all times.

How to Remove PUP ExpressFiles Tutorial

ExpressFiles is a program developed by Express Solutions. A number of Anti-Virus programs have flagged this program as a Potentially Unwanted Application. In many instances, it is bundled with additional programs on installation.

The program claims it offers users easy to search for various currently popular search terms. During our testing, the software never displays any search results, no matter the search words. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times. The program defines an exception rule in Windows Firewall, allowing it to connect to the internet without limitations and auto-update itself.

About Browser Hijackers

Precisely what is a PUP?

If you’ve ever downloaded a free application or shareware, chances are high that the computer can get installed with a bunch of unwanted applications. A PUA / PUP (potentially unwanted application / potentially unwanted program) is a software program that comes bundled with free software and you consent to install it on your PC. These are programs you almost certainly don’t want on your computer simply because it doesn’t give any valuable service. Despite being regarded as very detrimental, PUPs aren’t always viruses or malware One simple difference between PUP and malware is distribution. Malware is normally dropped by silent installation vectors like drive-by downloads while PUP gets installed with the consent of the computer user, who purposefully or unknowingly approves the PUP installation on its PC. Having said that, there is no doubt that PUPs remain bad news for PC users as they can be incredibly damaging to the computer in numerous ways.

Exactly how do unwanted programs look like?

Potentially Unwanted Programs appear in different forms and varieties, however, in the majority of instances, they are adware programs that exhibit irritating pop-up ads and advertisements on websites you explore. In addition, the majority of free programs these days come with some unwanted add-ons; in most cases an internet browser toolbar or browser modification like a homepage hijacker. They’ll keep track of your online routines, redirect your search results to risky websites where viruses can be downloaded and installed, hijack your home page, and slow your browser down to a crawl. Potentially Unwanted Programs occasionally act quite much like computer viruses or spyware. They might carry keyloggers, dialers, browser hijackers, and tracking components that gather system details, or tracks customer habits and relays this information to third-party firms. Even if the PUPs really aren’t basically malicious, these software programs still do absolutely nothing good on your personal computer – they will take valuable system resources, slow down your PC, weaken your computer security, and make your system more susceptible to trojans.

How do you avoid PUPs?

• Read cautiously before accepting the license agreement as it may have a clause about PUPs. • Always opt for the custom if you’re presented an option between “Custom” and “Recommended” Installations – never click Next, Next, Next blindly. • Have a top-notch antivirus program like Safebytes Anti-Malware which can protect your computer from PUPs. As soon as you install this software, protection from malware and PUPs is already switched on. • Think carefully before you download any kind of shareware or freeware. Disable or get rid of toolbars and browser extensions you don’t really need. • Only use official product websites for downloading programs. Stay away from download portals altogether as most websites compel users to download the software using their own download manager, which is often bundled up with some sort of PUPs.

What To Do If You Cannot Install Any Anti-Malware?

All malware is bad, but certain types of malicious software do a lot more damage to your computer than others. Some malware types modify browser settings by adding a proxy server or modify the PC’s DNS settings. In these instances, you will be unable to visit some or all of the websites, and therefore not able to download or install the required security software to remove the infection. If you are reading this right now, you have perhaps recognized that a malware infection is a reason for your blocked web connectivity. So how to proceed when you want to install an anti-malware application like Safebytes? Follow the instructions below to eliminate malware by alternative methods.

Install in Safe Mode

The Windows-based PC comes with a special mode called “Safe Mode” where just the bare minimum required applications and services are loaded. If the malware is set to load immediately when the computer starts, shifting to this mode may well prevent it from doing so. In order to enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSConfig and locate the “Safe Boot” options under the “Boot” tab. As soon as you restart the PC into Safe Mode with Networking, you could download, install, and update anti-malware software from there. Right after installation, run the malware scanner to get rid of standard infections.

Utilize an alternate internet browser to download antivirus software

Web-based malware could be environment-specific, targeting a specific web browser or attacking particular versions of the web browser. If you’re not able to download the anti-virus application using Internet Explorer, this means the virus is targeting IE’s vulnerabilities. Here, you need to switch to a different web browser such as Chrome or Firefox to download the Safebytes Anti-malware program.

Install and run antivirus from a Thumb drive

Here’s yet another solution which is creating a portable USB anti-virus software that can scan your computer for malware without the need for installation. Try these simple actions to clean up your infected computer using portable anti-malware. 1) Download Safebytes Anti-Malware or Microsoft Windows Defender Offline onto a clean PC. 2) Mount the pen drive on the same PC. 3) Run the setup program by double-clicking the executable file of the downloaded software, which has a .exe file extension. 4) Select the drive letter of the USB drive as the location when the wizard asks you exactly where you would like to install the anti-malware. Follow activation instructions. 5) Now, insert the thumb drive into the corrupted PC. 6) Run the Safebytes Anti-malware directly from the pen drive by double-clicking the icon. 7) Click the “Scan” button to run a full computer scan and remove viruses automatically.
