Required C000021a Unknown Hard Error Fix

To fix the root you are having, you need to do a system restore. To do that-

1. Boot into safe mode with command prompt
2. Go to Windows folder in c drive
3. Then proceed to system32 don’t and then to restore

Run it and choose a restore point when the issue was not there. In that look for rstrui.exe

This should generally fix the error.
