When I start my laptop the following does not work:
Desktop background is black
Trash is only displayed
Error comes: Path not found: C: \ WINDOWS \ system32 \ config \ systemprofile \ Desktop
Explorer can't start: An attempt was made to access a token which does not exist
Boot from the Windows installation media (DVD, or USB stick), start the installation, and then select and run the repair mode.
I have none of that. Did not get anything. Only the laptop

or, if not possible, buy a computer image with DVD. This contains an "emergency CD". You can read more about this here:

If you have all the data in a backup, you can also reset the laptop to factory settings. Then he is like new bought - all personal but gone!
Suspect, the operating system was blocked by Microsoft for lack of valid license.
