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.

Windows 10X is a new version of Windows that has been built from the ground up for new PCs and will begin shipping on hardware in 2021. It's built on top of a new modern version of Windows called 'Windows Core OS' that guts legacy components and features in favor of contemporary user experiences and enhanced security. This means everything from the Windows Shell to the underlying OS has been rebuilt with modern technologies.
As a result, Windows 10X does not support legacy Win32 applications at launch. Windows 10X PCs in 2021 will be able to run Microsoft Edge, UWP, and web apps. Legacy Win32 application support will arrive at a later date, however. When it does, Win32 applications will run in a secure container by default, meaning those legacy applications cannot affect system performance and battery life when closed. Windows 10X is a much more secure and stable OS as a result of this, as there's no opportunity for legacy apps to cause bitrot.
Windows 10X features a new shell of the user interface that has been built with modern technologies. It's an adaptive user experience that can adjust depending on the "posture" of your device. For example, with a foldable PC, the user might want to use it in several different ways; as a laptop, or tablet, or in tent mode for movies. Because of this, the user interface must adapt to provide the best experience no matter which way your device is being used. This also means that legacy shell elements, such as the Control Panel, File Explorer, and error dialogs and icons are gone on Windows 10X. As Microsoft has rebuilt the entire shell, it doesn't include any of the legacy things that make Windows 10 so inconsistent when it comes to UI. The Windows Shell on Windows 10X should be much more consistent. At launch, Windows 10X will only be available on traditional clamshell PCs aimed primarily at the education and enterprise markets. The platform will eventually ship on the new devices from factors such as foldable PCs, but that won't be happening in 2021.
