I turn on my computer. Windows 10 boots up and the desktop appears. I login and get to do my work. After a few minutes, the computer restarts by itself suddenly (no BSOD). Windows boots up and I get to do my work. However, it does not crash again.

If I shut down my computer and start it again, Windows crashes then restarts and everything starts working as it should.

Why is Windows crashing on the first boot after a shutdown?

What is the procedure to investigate the cause?


Auto-Reboot disabled

Auto-Reboot on crash is disabled but BSOD still does not appear.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\CrashControl\Auto-Reboot is set to 0.

  • BSOD only appears when you ask Windows to show it. Normally, Windows just logs the BSOD and restarts. So, what I am saying is: It still can be a BSOD.

    Take a look at the system event logs.

    I have auto-reboot disabled. So something must have gone horribly wrong that Windows failed to catch it?

  • @David I had the system event log system disabled (have enabled it now; let's see what that has for us). If I try to open the minidump, my VS2015 says "debugging older format crashdumps is not supported". It is weird that the BSOD does not appear but Windows manages to create a dump. So I guess Windows had control before the reboot.

  • The "Auto-Reboot" field in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\CrashControl is set to 0.

We could try run startup repair: press and hold the SHIFT key on your keyboard and click Restart. Then select Troubleshoot ->Advanced options ->startup repair In addition, check if you have any abnormal schedule task running to trigger the restart. If no, perform a Clean Boot to eliminate the third-party software conflict.

  • The desktop window appears and I can use the computer for a while before it restarts. I don't think there is an issue with startup. I'll try a clean boot next time.
