How to Fix Fatal Error c000021a

Among other things and innovations, Windows 11 brings to the table is the game mode. The game mode is a system designed to release some resources and optimize your system when Windows 11 detects that you are playing games. It also turns off automatic updates while the game is active. The game mode is active at all times and usually, everything works great but in some instances, it can sadly cause some performance issues. If you are one of these unlucky people where game mode is not working as supposed to do, don’t panic, we have a quick guide for you on how to turn it off.

1. Press ⊞ WINDOWS + I to open settings
2. Inside click on Gaming
3. Select Game mode
4. Click switch beside Game mode to turn it off
5. Close settings

Everything will be automatically saved and applied and you should not have any issues from now on. If for any reason you wish to turn game mode back ON, just follow the same steps and turn the switch to ON.

A lot of users lately reported getting an error that says, “The application has failed to start because its side-by-side configuration is incorrect”. This kind of error can pop up when you try to open a number of programs, regardless of their origin, the developer, and compatibility. Here’s the full context of the error message:

“<PATH OF THE EXECUTABLE FILE>, This application has failed to start because its side-by0side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail”.

This kind of problem has something to do with the C++ runtime package in the background. It could also be related to an error for a registry value. Whatever the cause is, you can fix this error with the help of some suggestions provided in this post. You can try to reinstall the application or check the registry setting or reinstall the suitable Visual C++ Runtimes or re-enable the Microsoft .NET Framework. For more details, refer to the instructions given below.

Option 1 – Try to reinstall the application

There are times when some supporting module for your application under the hood could have messed up the application. And so to fix that, you need to uninstall the concerned application and then try reinstalling it again. Once you’re done, check if it fixed the problem or not.

Option 2 – Try to change the Registry setting

• Tap the Win + R key combination to open the Run dialog box.
• Then type “Regedit” in the fields and tap Enter to open the Registry Editor.
• Next, navigate to this registry key: Computer HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows NT CurrentVersion SideBySide Winners x86_policy.9.0.microsoft.vc90.crt_1fc8b3b9a1e18e3b_none_02d0010672fd8219 9.0
• From there, look for a String value named “default” and double click on it.
• After that, change its Value data to match the one as the third value in BINARY.
• Now restart your computer to successfully apply the changes made.

Option 3 – Try reinstalling the appropriate Visual C++ Runtime

• You need to open the Event Viewer first by searching for it in the Windows Search box.
• After opening Event Viewer, look for the error events that are sourced by SideBySide.
• Next, look for the actual Visual C++ Runtime module that’s causing the error.
• Now download the module from the official website of Microsoft Support and then install it and see if it fixed the problem.

Option 4 – Re-enable the Microsoft .NET Framework

You could also try to disable the Microsoft .NET Framework then enable the latest version of the .NET Framework on your PC and check if the error is fixed.

There are times when system files get corrupted and if the Windows Update process finds the system’s integrity questionable, chances are, the update, upgrade or the installation may fail and you will only be getting an error code 0x80073712 instead of completing the process. The error code 0x80073712 indicates that a file needed by the Windows setup or the Windows Update is most likely missing or damaged. To resolve the problem, here are some suggestions you can try.

Option 1 – Try running the DISM Tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – 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 error 0x80073712. 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 3 – Try running the Chkdsk utility

You can also try running the Chkdsk utility to resolve the Windows Update error 0x80073712. 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 commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed.

Option 4 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 5 – Try running Microsoft’s online troubleshooter

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors.

Windows and Devices chief Panos Panay has revealed new focus sessions feature that will be in Windows 11 on his Twitter account today. He himself is referring to it as a game-changer especially with Spotify integration.

So what is a focus session?

From the video clip provided on Twitter, we can see that focus session users will be able to choose a specific task from the previously made task list, choose songs that will play in the background while the task is active, and set a timer for the chosen task with breaks. Maybe the best comparison and explanation would be a desktop google calendar task with music, basically, that’s it. A neat and good organizer inside your Windows 11 operating system. I think that this is generally a good idea and for sure it will find its audience.

If your VPN software blocks and disconnects the Internet or Wi-Fi connection as soon as it is connected, read on as this post will give you fixes to resolve the problem. This kind of issue is odd but not unheard of. Many users use VPN for privacy and security but if it causes internet connection problems, you have to pin down the root cause of the problem and fix it in order to continue browsing the internet with privacy and security. Here are some suggestions you need to check out to resolve the issue between your VPN software and network.

Option 1 – Try installing the latest version of the TAP adapter

Since all VPN software uses a TAP adapter which is mostly from OpenVPN, you might want to download and install the TAP adapter driver to resolve the problem.

Option 2 – Run the Network Adapter Troubleshooter

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Configure the client computer to use the default gateway

This kind of connection problem can occur when you configure the VPN connection as the default gateway on the remote network. In such a case, the VPN settings override the default gateway settings (TCP/IP settings). Thus, you have to configure the client computers in order to use the default gateway setting on your local network for internet traffic as well as a static route on the remote network for VPN-based traffic.

Option 4 – Try to use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could help you resolve the internet connection problem caused by your VPN. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Try checking the settings of your VPN software

If your VPN software has a built-in “kill switch” it prevents any internet usage every time there is a problem in connecting with the VPN server which explains why your internet connection is disconnected when your VPN software is connected. In addition, you could also try to change your VPN software’s protocol since all VPNs support multiple protocols. It could be that the protocol your VPN uses is blocked so try changing to another protocol and see if it fixes the problem.

Option 6 – Update the Network Adapter drivers

You might also want to update the Network Adapter drivers by following 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.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the “Windows could not find a driver for your network adapter” error, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

To reinstall the network adapter driver, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

If you have just updated your Mozilla Firefox browser as of late and you noticed that it’s showing wrong or no bookmark favicon at all, then read on as this post will provide you with potential solutions that can help you resolve the problem. The basic thing you can do to fix it is to either refresh or reset the cache for favicon and then force restart the favicon service. However, if you’ve already tried this and it didn’t work, then there are still other options you can try. You can try to rebuild the configuration file for the favicon or restart the favicon service. You could also try disabling all the add-ons on your browser or scan your computer for adware. For more details, refer to each one of the options laid out below.

Option 1 – Try to rebuild the favicon configuration file

Mozilla Firefox actually creates a file each time you bookmark a webpage and this is called “favicons.SQLite”. This file is located on your computer and for you to fix the issue in Firefox, you need to rebuild this file and in order to do that, follow these steps:

• First, you need to unhide the hidden files in your computer by enabling the “Show hidden files” option so that you’ll be able to see the hidden files in your computer.
• After that, navigate to this path: C:Usersyour_usernameAppDataLocalMozillaFirefoxProfilesyour_profile_name
• From there, you need to find the “favicons.SQLite” file and once you found it, delete it.
• Next, you have to open the Firefox browser and create the same favicon configuration file which should be automatically created.
• Now check if you can now see bookmark favicons on your Firefox browser or not.

Option 2 – Try to restart the favicon service

If the first option didn’t work, you can try to restart the favicon service instead. Restarting the favicon service can help if you do not see the correct bookmark favicon on your Firefox browser. To restart this service, follow the steps below.

• You need to first open the Firefox browser and in the address bar, type “about:config” and tap Enter.
• After that, you will see a page that displays a warning message. On that page, you need to click the “I accept the risk!” button to proceed.
• Next, using the search box on the page, look for the “devtools.chrome.enabled” option. The value for this option should be set to “False” by default.
• Double click on this option to set its value to “True”.
• Once done, go to Menu > Web Developer > Browser Console or you could also tap the Ctrl + Shift + J keys, alternatively.
• Afterwards, paste this command in the pop-up window that appears and then tap the Enter button: var fS = Components.classes["@mozilla.org/browser/favicon-service;1"] .getService(Components.interfaces.nsIFaviconService); fS.expireAllFavicons();
• Once you’re done, restart your Firefox browser to check if it fixes the problem or not.

Option 3 – Try to disable all the add-ons in Firefox

The next option you can try to fix the problem is to disable all the installed add-ons in Firefox. More often than not, add-ons can cause issues in the browser so it is possible that one of the add-ons in Firefox is causing it to show incorrect or no bookmark favicon. To resolve this problem, you have to disable all the add-ons by opening Firefox and then going to Menu > Add-ons or you could also tap the Ctrl + Shift + A keys. After that, go to the Extensions section and click on the respective Disable buttons for each one of the add-ons. Once done, restart your computer and check if you can now see the bookmark favicons or not.

Option 4 – Try scanning your computer using Windows Defender

It is possible that the bookmark favicon problem is caused by some adware in the Firefox browser so you have to scan your computer to check by using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. Microsoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

More information

The details described leading to speculation that the problem could be related to drivers that Microsoft is providing. On further tests, all Nvme drives that use the Microsoft driver have this problem, but Intel 905P, which has its own driver provided by Intel, is working at full power,”.
