Kaspersky finds nothing
Program logs in windows only confirms that the "winows shell" has restarted due to unknown reasons. No further information.
Problem even shows up in safe mode.
Did run "sfc /scannow"
Restoring to a previous state is not possible. Rstrui.exe accepts restoring to a previous state - but after rebooting - message sais that restoring was not made. No further information.
