Hi Bjoern.
That worked, thank you very much!
However, I still think this is a bug.
I found this: https://lists.samba.org/archive/samba/2017-January/206133.html
and followed the research.
When you logout FIRST, then shutdown: no problem.
When you shutdown (which is essentially the same as logout then shutdown) the NTUSER.DAT keeps locked.
So when I consider the first way your should be able to do that in the second way.
It's mostly a problem when you have to reboot after an update, upgrade or install.
However,
thank you!!!!
