In the web a lot advice about what to do if I forget my password - tips from harmful to useless.

Boot the system, usually fails when loading screen appears: lsass.exe - System Error with the message "Unable to initialize the SAM because of the following error: The device is attached to the system is not working. Error Status: 0xc0000001. Click OK to shutdown this system and reboot into Safe Mode, as detailed in the event log. " After clicking OK the computer restarts, and so - to infinity.
There is also this advice: delete the file logon.scr (WINDOWSsystem32), and rename the file cmd.exe logon.scr. After the reboot, allegedly after 15 (!) Minutes should (?) Open a command prompt window in which you want to dial EXPLORER, then supposedly you can log in with Administrator rights. Nothing doing! ..
