The most common cause of Error Code 0x8000ffff is that there is a problem within one of the system files or the registry entries on the computer. There are a number of reasons why a device could have an error in these places, from conflicting software commands to updates that were not installed correctly, to bugs within the system, to viruses or malware that have corrupted the necessary files.

Further Information and Manual Repair

There are several common ways that users can attempt to resolve the appearance of Error Code 0x8000ffff on their Windows devices. If you are not sure that you can follow these steps through to completion, you would be well advised to get in touch with a qualified computer repair technician to help you to finish out the repair process.

Here are the best methods to resolve Error Code 0x8000ffff on your Windows machine:

Method One:  Restart Your Computer

It may sound obvious, but one of the most effective ways to resolve Error Code 0x8000ffff on your machine is to simply reboot your computer. In some cases, the error shows up because there are processes that the system believes are still running when they really aren’t. Restarting your machine also allows your system to apply any previous changes that have been made and to mark any installations that have been undertaken as being complete.

Reattempt your update installations after you have restarted your computer to see if you are able to finish them out successfully.

Method Two:  Run the Windows Registry Repair Tool

The Windows Registry Repair tool is an asset that can make it easy for your system to scan for potential problems in the registry and notify you as to their status. In many cases, the Registry Repair tool can fix the problems that it finds all on its own, although in some cases, you may receive a message that states an error was found that could not be resolved through the program.

The simplest way to access the Windows Registry Repair tool is to do a search for it within the search bar in the Start menu. Once you begin to run the Registry Repair tool, it can take a while to complete its scan, so be prepared to wait for some time once you start it.

Once the tool has completed its scan of your system, it’s always a good idea to reboot your computer so that all of the changes that have been made to the system can be applied successfully to the operating system.

Method Three:  Run the Windows Fix It Tool

Another great tool to help in the resolution is the Windows Fix It tool. You can download it directly from the Microsoft website. Once you run it, it will complete a scan of your system to find any potential hang-ups and to attempt to resolve them. After you run the scan, it is a good idea to reboot your computer to allow all changes to be recognized and applied properly.

Method Four: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Easy Remove FoxTab From Windows

FoxTab Toolbar is a browser hijacking toolbar add-on for IE, Firefox, Chrome, and Opera browsers that claims that it allows you to access your favorite sites faster, and improving your overall search and browsing experience. 1-click access to search results, most popular websites, and web services directly from our Foxtab browser toolbar.

Fox tab will integrate itself into your browser, modifying the search engine, welcome page, and new tab. This toolbar may change some browser settings, display unwanted ads, and sometimes displays additional ads from its ad sponsor. Some of the settings that this toolbar changes can lower the security of your browser.

Upon installation the toolbar ads scheduled tasks in Windows, allowing it to run with your browser every time, and to automatically update itself. Several anti-virus programs have flagged this software as Malware and therefore it is classified as a browser hijacker and recommended for optional removal.

About Browser Hijackers

Browser hijackers (sometimes called hijackware) are a type of malicious software that modifies internet browser settings without the user’s knowledge or approval. These types of hijacks are rising at an astonishing rate across the world, and they can be actually nefarious and sometimes dangerous too. They are created to interfere with web browser programs for many different reasons. Often, hijackers will force hits to internet sites of their choice either to increase targeted traffic generating higher ad revenue, or to gain a commission for every user visiting there. Although it might appear harmless, these tools are made by malicious people who always try to take full advantage of you, so that hackers can earn money from your naivety and distraction. What’s more, hijackers can make the whole infected system fragile – other destructive malware and viruses will take hold of these opportunities to get into your computer system effortlessly.

How to know whether the browser is hijacked?

Symptoms that your internet browser is hijacked include: 1. your home page has been reset to some unknown webpage 2. bookmark and the new tab are also changed 3. default web engine is changed 4. you see unwanted new toolbars added 5. you’ll notice random pop-ups start showing regularly 6. your web browser starts running sluggishly or exhibits frequent glitches 7. Inability to navigate to particular sites, particularly anti-malware as well as other computer security software webpages.

How it infects your PC

Browser hijackers infect PCs in numerous ways, including via a file-share, a drive-by download, or an infected email. They can also be deployed via the installation of an internet browser toolbar, extension, or add-on. Also, certain shareware and freeware can put the hijacker in your PC through “bundling”. Browser hijackers can record user keystrokes to collect potentially invaluable information that leads to privacy issues, cause instability on systems, drastically disrupt the user experience, and ultimately slow down the PC to a point where it becomes unusable.

Tips on how to get rid of browser hijackers

Certain kinds of browser hijackers can be removed from your computer by deleting malicious applications or any other recently added freeware. Often, it can be a tough task to find and eliminate the malicious component because the associated file might be running as part of the operating system process. Also, manual removals require in-depth system understanding and thus can be a very difficult task for beginner computer users. Professionals always suggest users remove any malicious software including browser hijacker by using an automatic removal tool, which is easier, safer, and quicker than the manual removal process. Safebytes Anti-Malware detects all kinds of hijackers – including FoxTab – and eliminates every trace efficiently and quickly. Employ a pc optimizer along with your antivirus software to solve various computer registry problems, eliminate system vulnerabilities, and boost your computer performance.

Windows computer shuts down instead of Sleep
As you know the Windows 10 operating system is has a lot of features and some of them are related to turning off your computer in different ways in order to save power at different levels. These particular features are Shut down, Restart, Hibernate, and Sleep. However, there are times when you might encounter some issues when using any of the aforementioned features. One of these issues is when your computer shuts down instead of going to Sleep. This issue could be caused by several factors including a bug related to the Intel Management Engine Interface or IMEI driver as well as any misconfiguration in the power settings of the BIOS or UEFI. If your computer is going through this problem, read on as this post will guide you in fixing it. There are several potential fixes you can try to fix the problem. You can try to check the Sleep Advanced Settings or run the built-in Power troubleshooter or run the Power Efficiency Diagnostic Report. In addition, you can also try to troubleshoot the problem in a Clean Boot State or reset or update the BIOS.

Option 1 – Check 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. Make sure that the “Allow hybrid sleep” option is on.
  • 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 2 – Try to run the Power troubleshooter

The next thing you can do is to run the Power troubleshooter. To do so, follow these steps:
  • Go to Settings and navigate to Update & Security > Troubleshoot.
  • After that, look for the “Power” option from the given list of built-in troubleshooters and click on it.
  • Next, click on the “Run the troubleshooter” button to run the Power troubleshooter.
  • Once the troubleshooter is done identifying the problems, follow the next on-screen instructions to resolve the problem.

Option 3 – 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 put your computer to sleep again.

Option 4 – Try to run the Power Efficiency Diagnostics Report

You could also try to run the Power Efficiency Diagnostics Report to fix the problem. This tool is helpful and will help you analyze the status of the battery but note that this can be quite overwhelming especially if you’re not well-versed in this matter.

Option 5 – Try to update the BIOS

Updating the BIOS can help you fix the ATTEMPTED_WRITE_TO_READONLY_MEMORY BSOD error but as you know, 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 on your computer.
  • Now restart your computer to apply the changes made.
Note: If updating the BIOS didn’t help, you might want to consider resetting it instead.

Repairing a corrupt Group Policy in Windows
If you recently made some changes in your Windows 10 computer using the Group Policy Editor but they were not reflected and you got errors instead, it could be that your Windows computer wasn’t able to read the Group Policy file (registry.pol). To resolve this kind of issue, you have to repair the potentially corrupted Group Policy using the options given in this post. .As you know, Group Policy is a feature in the Microsoft Windows Active Directory which allows an admin to make changes in the features on Windows PCs that are on the network. So if the modifications you just made weren’t successfully applied, then there could be something wrong with the registry.pol file on the client or it could also be that the Group Policy folder is missing. To fix this issue in the Group Policy, you need to refer to the given suggestions below and make sure that you have admin privileges as you execute them.

Option 1 – Try to delete or recreate the missing registry.pol file

The entire settings of the Group Policy are stored in the registry.pol file so if it went missing, all the changes you make will not be reflected. The good thing is that you can recreate it but if the file exists and is corrupted, you need to delete it first before you recreate it.
  • First, go to the C:/Windows/System32/GroupPolicy/Machine location.
  • And from there, check if the registry.pol file exists or not. If it’s there, just delete it permanently by tapping the Shift + Delete keys.
  • Now it’s time to recreate the file. Just open Windows PowerShell with admin privileges by tapping Win + X + A keys.
  • After opening PowerShell, type this command: gpupdate /force
  • The command you entered will recreate the registry.pol file and will refresh the Group Policy. Restart your computer.

Option 2 – Try recreating the secedit.sdb file

The security settings of Group Policy are stored in the secedit.sdb file so if you made some changes to security and they weren’t reflected, you can try to delete and recreate the secedit.sdb file instead of deleting the Group Policy file. All you have to do is navigate to the C:/WINDOWS/security/Database folder and look for the secedit.sdb file and rename it or move it to another folder. After that, restart your computer. Once your computer has restarted, the secedit.sdb file will be created again.

Option 3 – Try to reset the Group Policy to default

You can also try to reset the Group Policy back to its default state. There are several ways you can do that. You can either use the gpupdate or the secedit command in the Windows PowerShell to do that. Resetting the Group Policy will resolve any issues that could be caused by its current settings.

Option 4 – Try to perform System Restore

System Restore can also help resolve the Group Policy issue. It could be that prior to the issue, you’ve made some changes in the system that might have affected the Group Policy. To undo these changes, perform System Restore.
  • First, 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 5 – Use the DISM tool

You can also try running the Deployment Imaging and Servicing Management or DISM tool. This tool will repair the Windows System Image as well as the Windows Component Store in your Windows 10 computer. So if there are any missing or corrupted folders and files, the DISM tool can restore and repair them. As a result, any system consistencies and corruptions will be fixed. To run this tool, follow these steps:
  • Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
  • After that, input each one of the commands listed below sequentially to execute them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • Dism /Online /Cleanup-Image /RestoreHealth
  • Once you’ve executed the commands given above, restart your computer.

How to Fix Error Code 22

Error Code 22 - What is it?

Code 22 is a type of Device Manager Error code. Device manager errors are reported by the drivers causing the problem. It indicates that the devices are disabled in the Device Manager. This error code is displayed in the following format:
This device is disabled. (Code 22)
It looks like a very simple matter to enable a device from the Device Manager interface but if the device fails to load then there are likely greater underlying problems with the drivers. Drivers allow hardware devices to communicate with other hardware devices and the operating system. Drivers contain instructions and operating procedures for devices. Without a driver, a hardware device will not function and may not even appear in the Device Manager.

Solution

driverfix boxError Causes

Common causes of error code 22 are:
  • Device is disabled
  • Driver is outdated
  • The driver is missing or corrupt
  • The previous attempt to update the driver failed
  • Device is damaged
  • The device is not configured as the default device

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.

Quick Tips and Tricks for Supreme Windows 11 Performance

Finally upgraded to Microsoft’s newest OS, but the performance is a bit sluggish? Here are a few useful tips you may not have thought about that could significantly transform your experience!

How to speed up Windows 11?

1. Disable startup programs

There are many programs that launch right on startup that really aren’t essential. This, in turn, causes your PC to launch and run more slowly.

To check which programs are enabled on startup, go into the Task Manager and select the Startup tab. Find every program that doesn’t need to launch immediately, right-click on it and press ‘Disable’.

This will not shut down the program in that instant. It’ll just prevent it from running automatically as you turn on your PC. You can always launch it manually when you need it.

2. Expand your memory and storage

If you want your PC to run super smoothly, you need to have enough memory to support that. This is especially significant for those of you who love to multitask. Upgrading your RAM gives your PC more space to store the temporary data it needs to complete processing tasks. In other words, processing takes a lot less time.

Your long-term storage is equally important. Hopefully at this point you’re already using SSD over HDD, since this type of storage offers a faster boot time.

In any case, we recommend expanding your storage capacity. The more files and data you store, the more there is to load, significantly influencing your PC’s speed. Larger storage capacity means new data and essential updates can be stored comfortably, preventing any strain on your PC’s performance.

3. Clean up disk space

If you aren’t willing to upgrade your storage just yet, the least you can do is clean up your storage right now. 

Aside from manually deleting stuff you no longer need, you can also get rid of temporary files that clutter up your storage and eat up performance for no reason. To get to them, click Windows + X and select ‘Run’ (or just type it in the search bar).

A small window will pop up, where you need to type %temp%. This will take you to a whole folder full of all the temporary files you can remove without thinking twice. 

For those who upgraded from Windows 10, there’s a neat trick to get rid of potential leftover files you don’t need on your brand new iteration. Only do this if you’re 100% sticking with Windows 11, though. Go to System > Storage > Temporary files. Make sure to only leave ‘Previous Windows Installation’ and ‘Windows Update Clean-up’ checked and click on ‘Remove files’.

Lastly, make use of Windows 11’s fantastic Storage Sense feature. Turning it on will enable your PC to constantly watch out for junk or unused files to optimize your PC’s performance to the maximum.

4. Install pending updates

This one should go without saying, but pending updates can be detrimental to your Windows 11 performance. The longer you leave them untouched, the more bugs the outdated programs and patches can cause. So, make sure to regularly check for updates and install them as soon as they’re available.

5. Disable visual effects

As cool as visual effects, animations, shadows and transparency are, they can also put quite a toll on your computer’s speed. On a newer setup this generally shouldn’t be a problem, but if you do notice a drop in performance, definitely consider turning off some of these settings.

To do this you can go to the Control Panel, System Properties and click the ‘Advanced’ tab. In the Performance section, choose Settings. If you’d like a quicker way to get to the dialog (Performance Options) with Visual Effects, you can also type sysdm.cpl in the search bar.

Once there, you can either have your PC choose what’s best, choose the best appearance or the best performance. The other option is to manually toggle the effects off and on. The biggest obstacles to speed are taskbar animations, window shadows, control/element animations and animations upon minimizing/maximizing.

In the same vein, you should go to Settings > Personalization > Colors and disable Transparency, to prevent your computer from doing overtime just to hit the aesthetic appeal.

6. Get rid of bloatware

Bloatware is one of the biggest culprits of slow computer speed. 

Pre-installed software that’s pretty much useless but takes up valuable system resources has been around since day one. No matter which device or platform you’re talking about. Luckily, a lot of it is removable, making it easy to lighten the load on your device.

To boost your Windows 11 computer, go to Settings > Apps > Installed apps. You’ll probably see a bunch of apps you don’t want or need. Click on the three dots next to each one you want to remove and press ‘Uninstall’. 

Aside from helping optimize performance, removing bloatware has another great benefit. Unfortunately, often this pre-installed software is quite vulnerable, exposing you to great risk of cyberattacks. So, removing it definitely improves your device’s security and gives you at least some peace of mind.

Summary

These are a few of our fastest tips for boosting performance. There are other, more complex and time-consuming ways, of course. If you’ve tried these quick ones and still need advice on how to improve your PC’s speed, feel free to reach out!
