You are right: Shutting down Windows 10 or 11, either from within the VM or from the Qube manager, does not really shutdown the VM, but puts it into hibernate Setting
powercfg -h off solves the issue for both Windows versions. The startup type of the services can be left at
Automatic, and manual starting and stopping the services is not needed.
So, let’s not forget to mention setting
powercfg -h off in the R4.1 documentation for Qubes Windows Tools!
For Windows 11, start and stop are much slower than for Windows 10, but this system is worse in many respects, although it seemed that this could not be possible!
Thanks a lot for clearing up this situation!
