Windows 7 freezing on shutdown
Windows just started freezing every time I shut my computer down. It goes to the "Shutting Down" screen, the circle goes roundy-roundy for several minutes, and then stops. It does this on every shutdown, and when I restart it (after holding down power button to force power off) it says it was not shut down correctly, but once you start Windows normally, everything functions correctly - at least until you try and shut down next time...
I am running Windows 7 x64 Build 7600. It shuts down perfectly if you boot up in safe mode, but hangs even with all non-Microsoft services disabled in MSCONFIG. It hangs on shutdown on every shutdown, for all users.
I downloaded the Developers' Tools, and ran a couple of traces, which I will try to upload here. They seem to show a COMCTL32 process that doesn't stop (if I'm reading it correctly, which is probably iffy...)
Any help would be greatly appreciated.
