hangs on initializing installation

Hello,

Updates are downloaded but are not being installed. Installation Status
showes "initializing installation..." while nothing occurs in the status bar.
I have left the computer up and running overnight without any progress. No
error messages received.

Thanks!

O/S: XP Media Center

I had the same problem. I also couldnt get my folder properties to show. I
found a temporary fix.

Press control + alt + delete, click on the processes tab at the top, find
inetinfo.exe, select it, and at the bottom left click end process.

I don't know why, all I know is that it works.
