Windows Update?

My laptop is doing a Windows update, but all the time it says "will be restarted". Is there no indication of how long it will be?

No, unfortunately not. You can really only wait

Try to wait a little longer.

If nothing really works after 1 hour, restart…

I do not know more than that.

Yes, definitely.

Cancel at this point and repeat it according to the following scheme: https://www.bestetipps.de/computer/windows-tipps/windows-10-update-dauert-zu-lange-loesung/

Unfortunately, no. Just wait and see. And don't interrupt the process.
