I just tried to shut my PC down, only to be told that "Windows can't shutdown because one or more services are still in use". When I check exactly what is preventing windows from shutting down, it simply says "Shutdown is preventing windows from shutting down or restarting". I had to "Force shutdown" which worked. I've restarted twice since the forced shutdown and not had a repeat of the issue. I did notice that the windows update icon was showing 5 times in the task tray just before I shutdown, could this be a bug/glitch? I'm on Windows 7 home premium x64, all up to date. The last progs I installed were Winrar and VLC yesterday. Nothing else since. I've googled and can't find much that matches my experience, some similar stuff but different behaviours. Any one any ideas?
