The server was running fine for many months but now suddenly it shows that the OS is not genuine anymore. The Software Protection service is not running. And I can not start it anymore
It is in German but it basically says: Cannot start Software Protection because The system cannot find the file specified. Screen-Shot-2016-08-26-at-09.20.45.png
just open regedit, HKLM\System\CurrentControl
and check the value it should be 0
