System Restore is one of the best ways to revert to the last stable state in Windows 11/10. However, sometimes it fails, and one of the conditions, when it does not work, is after a Windows Update. If you receive Stop Error 0xc000021a, and System Restore stops working after Windows Update, then it’s a known issue for Windows 11/10. In this post, we will share workarounds so that you can restore Windows 11 or Windows 10.
One of the scenarios where the problem occurs is when you clean install Windows, create a restore point, and then install Windows Updates. After installing the updates, when you try to restore, it fails. Instead, you get the Stop error (0xc000021a). It is possible that you cannot even return to Windows desktop in this situation.
When you perform System restore during this scenario, some files are restored only when the computer restarts. This is called staging. In this scenario, Windows restores the catalog files and stages the driver .sys files to be restored when the computer restarts.
However, when the computer restarts, Windows loads the existing drivers before it restores the later versions of the drivers. There is a mismatch in the driver version. Hence the restart process stops, and System restore doesn’t work after Windows Update.
