recently, I installed a new Windows Server 2019 VM on my HyperV 2019 in a customers network to use as a fileserver (SQL etc.).
However, 2 weeks ago after I installed some updates I could not login anymore because "ProfSvc failed to load the profile". I already tried about everything on Google Page 1-10 related to this error and I am certain that this is a problem with profsvc directly, not with the usual default profile stuff/local logon you read online everywhere that sometimes happens to Windows 10 systems. Also, not only I can not login, the SQL servers installed also can not start probably due to profsvc not functioning. The issue persists also in safe mode.
However, everything else on the server works and I can even use mmc to remote manage the server without a direct console logon; My main problem is that nothing indicates that something is wrong with profsvc or the server, Eventviewer etc. do not show any useful info and dism/sfc/chkdsk say everything is fine. I can even restart the profsvc service without any issues.
Everytime I experimented on it I just set up a restore point in HyperV before installing the updates and restored that and then the server functions as it should (Restarts etc. possible).
Only installing the cumulative updates causes this problem, starting with the latest for Server 2019.
As I mentioned, I (and colleagues) tried about anything on the net and I just cannot for the life of me solve this issue, I hope someone on here had a similar issue before or has some really outlandish ideas.
Thanks in advance to anyone who answers this thread.
