We have 2 Delivery Controllers on 1912 (no CU) and we tried to upgrade them tonight to CU and get his with:




We found this:




Which pointed to here on both servers:


So we deleted it and rebooted and tried the upgrade again to find we get the same error and the reg key returns.

Anyone seen this?

Did you checked if there is a Windows update that is failed? 

Maybe it keeps trying to reinstall when booted the vm. Try to disable the windows update service. 


You could also check the below registry values, the first you already checked, but take a look at all the others:


HKLM\System\CurrentControlSet\Control\Session Manager value: PendingFileRenameOperations
HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired
HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\RebootPending
HKLM\Software\Microsoft\Updates value: UpdateExeVolatile
