STATUS_SYSTEM_PROCESS_TERMINATED

STATUS_SYSTEM_PROCESS_TERMINATED error occurs when a critical process, such as WinLogon (winlogon.exe) or the Client Server Run-Time Subsystem (csrss.exe) fails. Once the kernel detects that either of those services have stopped, it raises the STOP 0xC000021A error.

This error may have several causes, including:

Mismatched system files have been installed.

Solution

Collect the Memory Dump File

If you have a recent backup of the VM, you may try restoring the VM from the backup to fix the boot problem. To resolve this problem, the crash dump will need to be analyzed. Collect the memory dump file for the crash and contact support. To collect the dump file, follow these steps:

Attach the OS disk to a new Repair VM

Use steps 1-3 of the VM Repair Commands to prepare a Repair VM.

Locate the dump file and submit a support ticket

On the repair VM, go to windows folder in the attached OS disk. If the driver letter that is assigned to the attached OS disk is F, go to F:\Windows.
Locate the memory.dmp file, and then submit a support ticket with the memory dump file.
