...there should be a place that lists all the pending updates.

1) Before you apply the updates and log off, go there and check the updates that are listed. My guess is that you will find only one update. Make a note of the name of the update.

Here's an example from my PC. What the update list might look like:

Update for Windows Mail Junk E-mail Filter [April 2009] (KB905866)
Security Update for Windows Vista (KB960803)
Security Update for Windows Vista (KB952004)
Windows Malicious Software Removal Tool - April 2009 (KB890830)

2) Go ahead and apply the update and recycle your PC.

3) When your PC comes back up, go to Windows Update again and check if that same update is *still* there, even though you just applied it.

If it is, post the name of it here (include the code number).

If it is not, feel free to tease me for getting it wrong.
