Bitlocker-API eventlog shows BL is suspending on its own after update installations RRS feed

  • Question

  • Win10 v1803/1809/1903 clean install in a VM - no additional software but windows. Build is the latest of each version. All builds had that problem.

    Bitlocker is activated for c: using a vTPM together with a PIN.

    Whenever OS updates (not feature updates but standard monthly OS updates) are installed or uninstalled and a reboot is required, the event log shows that BL suspends after the reboot.

    Log: Microsoft-Windows-BitLocker-API/Management, Event 773, source Bitlocker-API

    Message: Bitlocker was suspended for volume C:

    --

    Problem for us is: we are monitoring the eventlog for this event since we would like to make sure, BL is NOT suspended at any time. So this suspension triggers alerts all the time, for ALL machines in the network.

    This is a FALSE alert, since Bitlocker is NOT suspended at any time. So something writes this event although BL is NOT EVEN suspended.
