windows update stops, and PC cant restart

I was installing an update when right in the middle it stops. If I try to restart windows it fails on the windows loading screen, forcing me to restore windows which I hate to do because it messes up my Flight Simulator program. Please advice needed. I didn't get any error message it just completely goes dead and leaves me clueless.

Did you also try installing the Windows Update in the safe mode with network support. Did the same thing happened then?

I never installed it safe mode before, is this to be done regularly.

Neither have I but it is worth giving a try just in case the updates don't install in the normal Windows environment. I am not even sure whether they would get downloaded in the safe mode like many other applications do.

Thanks for advice , I may have to try that.
