Greetings,
I receive a BSOD everytime I restart windows 8.1 or whenever windows restarts automatically to install updates (although it finishes updating successfully on reboot) with error code 0xc000021a. Besides that, the PC works normally. A few days ago the problem was reversed, i.e. Windows crashed on shut down with the same error but not on restart, this happened after I uncheched the Turn on fast startup option in power options which apparently solved similar problems for other people. I had to perform a Windows Refresh, keeping both files and installed apps intact, to reverse the PC in the previous condition so now it crashes again on restart but afterwards boots normally, though with some delay. I tracked the problem to Winlogon process terminating unexpectedly but I don't know how to fix the problem since a reinstallation of Windows didn't solve it. I suspect that a third party program is causing the problem and since I kept all of them after the refresh it still causes problems. Since I am not an expert however I could be totally wrong. The last incident happened today (18/02/2014) on restart due to a windows update. I would greatly appreciate any help offered on this matter.
Thank you
