I've had this problem twice on x64 7077, when I go to shut down, it just stays at the shutting down screen and doesn't turn off, I fell asleep not knowing it was left on and it was on for like 10 hours.
And sometimes I've had to force shut down because some programs don't close.
I have the same issue. System shutdown hangs go as far back as Win95, and usually are caused by the system waiting on a service to close. Why it won't end or close could be a few different things.
Unfortunatley there's no direct information about the shutdown process in the event viewer.
I've gone through many different sources and tried a ridiculous amount of things in order to solve the issue. The first one was a restore point. That did the trick, however the hanging started again. I had read elsewhere that others experienced that - after a restore point working, system restarted fine for a bit, then started getting stuck again -.
The other obvious test is to try it in safe mode. This is where I think my issue with it deviates from most others, in that for them, they can restart in safe mode, suggesting that there's a higher level service, or outdated system driver causing their shutdown problem(s).
Yet for me, I can't even restart in safe mode. There's something considerably worrying about that.
THE only connection I can draw from my actions that my relate or influence any of this, is when trying to do a firmware update on my Razer mouse. However when there was no success, I reverted back to the last known supported drive/firmware combination, and as far as the mouse goes, everything is fine.
I've tried clearing any cache, hoping that if the system is still looking for something related to the firmware update process, that it would clear it, but have been unsuccessful.
The only other thing I've noticed, is that registry programs report to me that there's numerous Active X 'issues.' Yet none of the registry entries are removable. It's actually the first time I've ever had regedit deny me doing something.
