Fix DRIVER_CORRUPTED_EXPOOL Error

If you suddenly encounter the DRIVER_CORRUPTED_EXPOOL Blue Screen of Death error when using your computer, then there might be some issues with the device drivers on your Windows 10 computer. This kind of BSOD error can occur at any point while you are using your PC. Its main cause is due to some error in the System Pool where a driver becomes incompatible with the operating system or when the configuration files get corrupted for some reason.

If you are one of the users who are currently inconvenienced by the DRIVER_CORRUPTED_EXPOOL error, worry not, as this post will give you some potential fixes that might help resolve the problem.

Option 1 – Perform a System Restore

Performing System Restore might help you in fixing the DRIVER_CORRUPTED_EXPOOL Blue Screen error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

  • Tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 2 – 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 DRIVER_CORRUPTED_EXPOOL error. 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 3 – Update the Device drivers

The device driver installed in your computer might be incompatible with your operating system which is the reason why the DRIVER_CORRUPTED_EXPOOL Blue Screen error occurs. To fix that, you have to update your device drivers.

  • Tap the Win + R keys on your keyboard to open the Run dialog box.
  • After that, type “msc” in the field and hit Enter or click OK to open the Device Manager.
  • After opening the Device Manager, update all the outdated Device drivers on your computer.
  • Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
  • Now restart your PC and check if the BSOD error is fixed or not.

Option 4 – Uninstall any faulty device drivers

  • Tap the Win + R keys on your keyboard to open the Run dialog box.
  • After that, type “msc” in the field and hit Enter or click OK to open the Device Manager.
  • From there, look for any device driver which has a yellow exclamation mark which indicates that something is wrong with them.
  • And then right-click on each one of them and click on Uninstall.
  • Once you’re done uninstalling the faulty drivers, restart your computer and allow your computer to reinstall the drivers you just uninstalled.

Option 5 – Try running the System File Checker

System File Checker or 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 that might be causing the Machine Check Exception BSOD error. 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

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 6 – Try updating the BIOS

As you know, the BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “msinfo32” in the field and press Enter to open System Information.
  • From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
  • After that, you should see the developer and version of the BIOS installed on your PC.
  • Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
  • If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
  • Now double click on the downloaded file and install the new BIOS version in your computer.
  • Now restart your computer to apply the changes made.

Option 7 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

There is no internet when WIFI is connected
If your WIFI signal is strong but you can not connect to the internet then keep reading in order to find out why this happens and what can you do to fix it. One very important thing to know and understand is that WIFI and the internet are two different things and that they altho connected and working together are basically 2 things. WIFI is a name for a group of technologies that are using radio vawes to connect to the router in order to access the internet. The Internet itself is series of computers all connected in LAN. Think of WIFI like some invisible cable that connects your computer to the router. When we put things into perspective this way it becomes clear that we can indeed have a strong WIFI signal and that we are connected to the router but the router itself is not connected to the internet. So basically troubleshooting an internet connection is troubleshooting the router itself. The most common approach is to reset the router, turn it off, then back on, check cables, etc. But be sure that if your WIFI signal is strong and you can not access the internet it is a router issue.

Windows computer goes to sleep automatically
If your Windows 10 computer or laptop keeps on going to sleep randomly even when you’re using it, read on as this post will walk you through the process of resolving the problem. There are a number of users who reported about how their Windows 10 computers would automatically go into Sleep Mode. One particular user claimed that when he installed a fresh Windows 10 version he began experiencing the same problem. It turns out that the screen goes to sleep but what’s odd is that the power lights and the keyboard are still working. The computer is also warm to touch which shouldn’t be the case when it is in sleep mode. And when some users tried checking the event log, it showed them that the computer didn’t actually go into sleep mode but it shut down instead. To fix this issue, here are some possible fixes that could hopefully work.

Option 1 – Edit the Power Plan settings using Control Panel

  • Click the Cortana button and type “control panel” in the field and select the appropriate result to open Control Panel.
  • After opening Control Panel, click on the Power Options.
  • From there, select the “Edit Plan Settings” option and make sure that the option to “Put the computer to sleep” is set to Never.

Option 2 – Edit the Power Options using Settings

  • Tap the Windows key + I to open the Settings app.
  • After that, select Settings and go to the Power & sleep section.
  • Next, set the system to “Never” when the device is running on battery power or plugged in.
  • Now restart your computer to make sure that everything is working properly.

Option 3 – Try running the Power Troubleshooter

Another option that could help resolve the problem is the Power Troubleshooter. This built-in troubleshooter in Windows can help you get things up and running again.

Option 4 – Troubleshoot Sleep Mode issue in a Clean Boot State

The issue with Sleep Mode might be caused by some third-party programs installed on your computer. This program might be the one that puts your computer to sleep and so to isolate this possibility, you have to put your PC in a Clean Boot State using 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.)
  • After that, try to install the Windows Updates or upgrade again.

Option 5 – Try checking the Sleep Advanced Settings

  • Click on the Windows key and type “control panel” in the field and select the related search result.
  • Next, select the Security and Maintenance option and click on the Power Options.
  • After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.
  • Now click on the Change advanced power settings button and a new window will appear.
  • Then look for the “Sleep” option and expand it to select the Allow hybrid sleep” option. Turn this option off and close all the opened windows.
  • Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.

Option 6 – Try installing v9 or 10 of the MEI or Intel Management Engine Interface

Note that this option only applies to users who are using an HP laptop. And if your motherboard does not support Hybrid Sleep, you might have to downgrade the Intel MEI to version 9 or 10. To install v9 or v10, you need to go to the HP Drivers & Downloads page and look for the MEI driver version 9 from the website’s Driver Chipset section. Once you’ve downloaded the driver, install it and if a dialog box warning pops up, simply ignore it and proceed.

Option 7 – Update the device drivers

  • Reboot your computer into Safe Mode with networking support.
  • Tap the Win + R keys on your keyboard to open the Run dialog box.
  • After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
  • After opening the Device Manager, update all the outdated Device drivers on your computer.
  • Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
  • Now restart your PC and check if your computer is now back to normal.

Linkury Smartbar Engine Removal Guide for Windows

Linkury Smartbar Engine is a Brower Toolbar for Internet Explorer. Upon investigation, we discovered that this toolbar does not work with the latest versions of Internet Explorer.

From the Author:

What the Smartbar does: – Changes the default search engine in your web browser’s built-in search box. – Changes the default home page of your web browser. – Adds alternative “page not found” functionality. – Enable search from the address bar of your web browser. – Allows software updates of the application once a new version is released. – Adds, removes, or modifies components interacting with search input fields.

While installed, users may see additional unwanted ads throughout their browsing sessions.

Several anti-virus applications have marked this toolbar as a Browser Hijacker, and it is not recommended to keep it on your computer, especially if you are using a newer version of internet explorer that renders this toolbar useless.

About Browser Hijackers

Browser hijacking means a malicious program code has taken control over and modified the settings of your browser, without your permission. Browser hijackers will do a number of things on a computer. These are typically used to force visitors to a particular site, manipulating web traffic to earn ad revenue. It may appear naive, but the majority of these sites are not legitimate and may pose a serious threat to your online safety. They did not just screw up your web browsers, but browser hijackers can also modify the system registry, leaving your computer susceptible to other attacks.

How you can determine if your browser is hijacked

When your browser is hijacked, the following could happen: home-page is changed; you see new unwanted favorites or bookmarks added, usually directed to advertisement-filled or pornography sites; the default browser settings are changed and/or your default web engine is altered; you find unsolicited new toolbars added; never-ending pop-up adverts appear and/or your web browser pop-up blocker is disabled; your web browser starts running slowly or exhibits frequent errors; you can’t visit specific websites like home pages of security software.

Precisely how browser hijacker infects computer systems

Browser hijackers could use drive-by downloads or file-sharing websites or perhaps an e-mail attachment in order to reach a targeted computer. They may also come from any BHO, browser extension, add-on, toolbar, or plug-in with malicious intent. A browser hijacker can be installed as a part of freeware, shareware, demoware, and fake programs. A good example of a well-known browser hijacker is the latest Chinese malware called “Fireball”, which has infected 250 million PCs across the world. It works as a hijacker but can be turned into a fully functioning malware downloader afterward. The existence of any browser hijacker malware on your system could substantially diminish the web browsing experience, monitor your internet activities that lead to serious privacy concerns, create system stability problems and ultimately cause your PC to slow down or to a nearly unusable state.

Removing browser hijackers

Some kinds of browser hijackers can be removed from your computer by deleting malicious software applications or any other recently added freeware. At times, it could be a tough job to find and eliminate the malicious program since the associated file could be running as part of the operating system process. Also, manual removals require in-depth system understanding and thus can be a very difficult job for novice computer users. Browser hijackers could be effectively removed by installing and running an anti-malware program on the affected PC. To eradicate any kind of browser hijacker from your laptop or computer, you could download this certified malware removal application – SafeBytes Anti-Malware. Utilize a system optimizer together with your anti-malware software to fix various computer registry problems, eliminate computer vulnerabilities, and enhance your computer's overall performance.

Help! Malware Blocking Anti-virus Installation And Access To The Web

Practically all malware is bad, but certain kinds of malware do a lot more damage to your computer than others. Some malware sits in between the computer and your net connection and blocks some or all websites that you really want to check out. It would also block you from installing anything on your machine, especially anti-virus software. If you are reading this now, you have probably recognized that a malware infection is the real cause of your blocked web traffic. So how to proceed if you need to download and install an anti-malware application such as Safebytes? There are some steps you can take to circumvent this issue.

Eliminate viruses in Safe Mode

If the malware is set to load at Windows start-up, then booting in Safe Mode should prevent it. Only the minimum required applications and services are loaded whenever you start your laptop or computer in Safe Mode. You need to do the following to remove malware in Safe mode. 1) After switching on the computer, hit the F8 key before the Windows splash screen starts to load. This should bring up the Advanced Boot Options menu. 2) Select Safe Mode with Networking using arrow keys and hit ENTER. 3) As soon as this mode loads, you will have an internet connection. Now, utilize your web browser normally and navigate to https://safebytes.com/products/anti-malware/ to download and install Safebytes Anti-Malware. 4) Right after installation, run a complete scan and let the program get rid of the threats it detects.

Switch over to some other browser

Web-based malware can be environment-specific, aiming for a particular web browser or attacking particular versions of the web browser. The best solution to overcome this issue is to choose a browser that is well known for its security features. Firefox has built-in Phishing and Malware Protection to help keep you safe online.

Install antivirus on a USB drive

To successfully remove the malware, you will need to approach the issue of installing an antivirus program on the infected computer system from a different angle. To run antivirus using a thumb drive, follow these simple measures: 1) On a virus-free computer, install Safebytes Anti-Malware. 2) Plug the Thumb drive into the clean computer. 3) Double click on the exe file to run the installation wizard. 4) Choose a USB drive as the location when the wizard asks you where you wish to install the software. Follow activation instructions. 5) Transfer the pen drive from the clean PC to the infected PC. 6) Double-click the antivirus software EXE file on the USB flash drive. 7) Simply click “Scan Now” to run a scan on the affected computer for malware.

How to Fix Unknown Hard Error in Windows 10
The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work. Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC.

Once you have that sorted out, follow the steps below.
  • 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.

  • After that, switch to the General tab and click the option for “Normal Startup”.
