Can you give me an error number? Hit Start and in the dialog box type in (or copy paste it from here lol) %windir%\WindowsUpdate.log
Hit enter. It should open up your windows update log in notepad. Click Edit and select "Find" type Fatal in the dialog box and hit find next.
Sounds like you will have a bunch of duplicate entries so keep hitting find next until you get to one on (or near) today's date (what ever "today" is when you do this). You will get an entry like this:
2009-06-30 01:30:01:920 2832 1180 COMAPI FATAL: Unable to complete asynchronous search. (hr=8024400E
The error number in this case is 8024400E (which I highlighted lol). Write it down and give it to me, or google it.
I found a thread with a similar problem at the Microsoft forums, but they have not resolved it yet. You can read it HERE
but I think you have done all they suggested so far except deleting the pending XML file. To do that (delete the pending XML file) hit start and type CMD in the dialog box. CMD will appear at the top, right click it and select "Run as administrator." WHen that opens up, type in (note there are 2 commands that need to be entered separately):
cd windows\winsxs (hit enter)
del pending.xml (hit enter)
Reboot and see if it is still happening. You DO have SP1 installed don't you?
NOTE: I just noticed you said you can't get the command prompt? Have you tried it the way I suggested? If so have you tried it by Start> All Programs> Accessories and then right click on Command prompt and select run as admin?
Tell me if any of this helps.
