Thanks for your help.
The windows update service is crossed out and red instead of green when I try to start it. When I hit <Update now> I get an error message, that the service is not running. I tried to install the new updates manually, but that did not work either. And today
I put the original harddisk back in and everything worked fine.
This is what I find in the log file:
