Windows Update Registered Incorrectly-Windows Xp Tips and Tricks-Windows Xp Tips and Tricks

Windows Update Registered Incorrectly

Fortunately, this occurrence does not happen very often at all. But, if you do find an instance where you have already installed a particular update, but Windows is asking you to install it again. This is due to an update that did not register correctly. 

To fix this, you will need to delete the registry key associated with the update, then reinstall the update. Here's how:

Warning: Making mistakes while editing the Windows Registry can have serious effects on your Windows installation. Be sure to make a backup copy prior to making any changes.

At the Windows update web page, note the KB article number (six digits) associated with the incorrectly registered update.

Go to Start>> Run. Type in: regedit [Enter] or click OK.

Drill down to the following registry key:

HKEY LOCAL MACHINE\SOFTWARE\Microsoft\Updates\Windows XP\SP2 (could possibly be SP1 instead of SP2)

Click once on the SP2 entry to empty its contents into the right pane.

In the right pane, locate the KB article number that you noted earlier.

Right click the KB article number and select Delete from the resulting menu.

Exit the registry editor saving the changes.

Restart your computer and then reinstall your Windows update.
