Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:
“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete)
If you’d like to know more, you can search online later for this error: 0xc000021a”
This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.
Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.
Performing System Restore can also help you fix the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” 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.
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 to good system files that might be the cause why you’re getting the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. To run the SFC command, follow the steps given below.
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:
Rebuilding the BCD can help you in fixing the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error.
The commands you entered should rebuild the BCD and repair MBR.
You can also run the Chkdsk utility to resolve the problem. 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.
winmgmt /verifyrepositoryAfter you enter the command, if there is a response saying, “repository is not consistent”, then the repository has an issue. If not, then something else is causing the problem. Since you are certain that corruption exists in the WMI repository, then here are some suggestions you need to check out to repair or rebuild the WMI repository.
“Code 800B0100 Windows Update encountered an unknown error.”
Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c.
There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:
• Computer malware has infiltrated your device.
• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.
• When there are mismatched system files installed or system upgrading process failed or still incomplete.
• Premature unloading of Wbemprox.dll
• Newly installed third-party software is not compatible with the operating system.
• There are corrupted, outdated, or incorrectly configured device drivers.
• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.
• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.
In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately. However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.
taskkill /IM "processname" /T /F processname – it is the name of the process which you can see on the Details tab of the Windows Task Manager. /IM – it is the one that specifies the image name of the process, which follows, that is to be terminated. /T – it is the one that kills not just the main process but also the child process. /F – it is the one that terminates the process forcefully.
wmic process where name='processname.exe' deleteNote: In the given command, you need to replace “processname.exe” with the name of the particular process you want to terminate which is found in the Details tab of the Windows Task Manager.
kill -id pidNote: In the given command above, “pid” is the Process ID number of the process you want to terminate. And for you to identify this number, you need to open the Details tab of the Windows Task Manager once again and take note of the number against the process you want to get rid of. Alternatively, you can also run the following command in the PowerShell prompt that you’ve pulled up to get the process ID number:
Get-ProcessFor example, “5364” is the process ID number for the DimScreen.exe process which is the process you want to terminate. In order for you to kill this process, you need to type in this command:
kill -id 5364
22H2 update for Windows 11 will arrive later this year and although Microsoft is not releasing anything big there will be some interesting improvements and fixes. We take a look at some that caught our attention.
One of the most interesting upcoming features is enhanced phishing protection. Microsoft Defender SmartScreen will be upgraded to alert users when they try to store passwords in plain text files and also if they accidentally type in a Microsoft account password on phishing sites.
"These enhancements will make Windows the world's first operating system with phishing safeguards built directly into the platform and shipped out of the box to help users stay productive and secure without having to learn to be their own IT department,"

Finally, Windows File explorer is getting tabs that will allow much easier management of folders and files inside it.
It is confirmed that Microsoft is also working on a new 'HOME' sidebar that should be modern in design and in features including OneDrive so you can find everything in one place.
Pinning of favorite files was also mentioned so you can easily pin favorites for quick access.
Windows 11 has brought back widgets in a new way and from all the feedback users are loving them. Currently, you have a widget sidebar on the left part of the screen where you have your chosen store widgets but from the Microsoft teaser, we will have soon the option to have them in full screen.
If you are using a widget for reading news, blogs, etc. this feature will be very good since you will be able to use your whole screen for information and not just a part of it.
Another new feature is 'suggested actions' which is going to be particularly useful in apps like Microsoft Teams. With this new feature, you can highlight a date in a Teams message and Windows will suggest actions.
For example, if you highlight a date, you'll see a recommendation to create an event in Microsoft Calendar for that day.
