Hello guys,
I had 3 PCs in my company with this issue.
All of them showed problems with Skype in event viewer so I uninstalled it.
On two problem remaind and what I noticed Windows changed region. I set it back but it didn't help.
After that I could notice some Problems with domain. I readded those Machines to domain. One of them worked fine again.
And on the Last one user profile was corrupted after windows Update.
