Weird loop windows activation

After upgrading to 3810 My windows keeps asking to re-activate. Bet when I try to activate win says the system has already been activated, then loops to the login screen again. Is this a known problem? How could i re-install windows to solve this? I cannt reach the vm andf I dont want to loose my vm.

Not working

To use this solution you need to get into windows first. But same problem in safe mode.

 

Hello,

Can you please clarify "the same problem in safe mode"
1) you boot in Safe mode -> activate and see already activated
2) you cannot boot in safe mode? (Virtual Machine -> send keys -> F8)

 

Safe mode

When I start the vm in safe mode It also loops around the login / acivation. I cannot enter Windows to change anything.

 

Windows repair will help in this case
