This is what I have done so far;
When I try to shut down it hangs on Shutting down.
What I have done so far to solve Windows 7 slow/won’t shutdown
Started the pc in Safe Mode the pc shuts down without any problems
Restored to a previous Restore Point in Safe Mode
Uninstalled various unwanted applications and toolbars
Did all the usual Disk Cleanup, run Auslogic Boot Speed, removed temp files, defragged the hard drive and cleaned and defragged the registry
Restarted in normal mode
Removed applications that did not need to start at Windows Startup
Performed a Clean Boot
Clicked the General tab, and Clicked Selective Startup
Under Selective Startup unchecked Load Startup items
Clicked the Services tab, checked the Hide all Microsoft Services box, and then Disabled All services except the Antivirus software
Clicked OK, Clicked Restart.
But after restart and try to shut down again there is a yellow exclamation mark on the Shutdown button indicating that there are Windows Updates to install! If I click Shutdown the problem returns, I have to shut down windows by pressing the power button. When I power on again and try to install Windows Updates it hangs on “creating a restore point”.
Have had a look at the Event Manager which produced this list which loaded all drivers except mostly the ones ending with @ nettun.inf, @netrasa.inf, @netavpna.inf, @netrasa.inf etc. these are mostly to do with internet connection, although there are no problems connecting to the internet. Too many “Did not load drivers” to list here as it is a 130 page Word document! Device Manager does not show any problems with any of the drivers!
So I have come to the conclusion that there is a problem with Windows Updates, which is stopping Windows to shut down but can’t figure what it is. Will running the “Automatically diagnose and fix common problems with Windows Update Fix it” from http://support.microsoft.com/kb/971058be a good idea? Any suggestions welcomed. Only problem is I cannot get to the broken pc easily or quickly so I may not be able to act on any suggestions any time soon.
