Re-install Windows Update files

http://download.windowsupdate.com/v6...gent20-x86.exe

Note If you have an x64-based computer, visit the following Microsoft Web site:
http://download.windowsupdate.com/v6...gent20-x64.exe

Click Save in the File Download-Security Warning dialog box, and then select the location where you
want to save the file.
Double-click the file that you saved

NB - A note from Torgeir Bakken [MVP]

Note that if it says "Install is not needed since Windows Update Agent is already installed.", run
the exe with the command line switch /wuforce, like this:
WindowsUpdateAgent20-x86.exe /wuforce

Close IE and then restart IE and try visiting the WU site again.
