WINDOWS UPDATES



For Vista and possibly Windows 7 -

The update uninstall method in Windows Vista is quite different than that in Windows XP.

The uninstall folder for each individual update no longer exists in Vista and the uninstall information is stored by Volume Shadow Copy service.

After every update, Volume Shadow Copy service only backs up the updated files.

So with Vista, it is a differential backup rather than a full backup of the uninstall files
in Windows XP.

This backup mechanism is used to save disk space.

So basically, you cannot manually remove the uninstall files from the computer.
