How to remove a Windows Update in Vista
If the fix works I recommend that you 'hide' it so that it doesn't get reinstalled automatically.
Instructions below:
If you don't want Windows to install an update, you need to hide it.
Open Windows Update by clicking the Start button . In the search box, type Update, and then, in the list of results, click Windows Update.
In the left pane, click Check for updates.
When Windows finds updates for your computer, do one of the following:
Click the link that tells you important updates are available if you have important updates to hide.
Click the link that tells you optional updates are available if you have optional updates to hide.
Right-click the update you don't want to install, and then click Hide update. The next time you check for updates, the update won't be automatically selected or installed.  If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
