Blue Screen Status System Process Terminated Stop Code 0XC000021A
This error indicates a problem with either Winlogon.exe or the Client
Server Runtime Subsystem (CSRSS). It can also be caused if a user with
administrator privileges has modified the permissions of certain system files such that Windows cannot read them.
To fix the problem, you’ll have to install a second copy of Windows and then repair the file permissions from there.
