BSOD Stop c000021a {Fatal System Error} First thing on initial startup RRS feed

  • Question

  • I have a few machines that intermittently at initial startup get the BSOD with c000021a {Fatal System Error} The windows Subsystem process terminated unexpectedly with a status of c0000005 (oxfc871b2f ox00aoec90) This system has shut down.

    This only occurs first thing in the morning and the machines run fine the rest of the day.  It appears it could be an update not for sure.  Please if you have a fix I would appreciate it.

  • Hi Jim.

    The STATUS_SYSTEM_PROCESS_TERMINATED (0xC000021A) bug check indicates that an error has occurred in a crucial user-mode subsystem; this error occurs when a user-mode subsystem, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), has been fatally compromised and security can no longer be guaranteed.
    You could ask this question in the Microsoft Community for Windows, which is more appropriate for this kind of topic; remember to upload the .DMP file created by Windows at the bug check's time to your OneDrive, make it publicly accessible and post the URL in your question's post.

    Bye.
