Windows 7 (and Vista) update differently than previous Windows editions.
They downloaded updates can *not* be reused in 7/Vista because they come
down as packages that compromise the updates. Component Based Servicing
is the mechanism that installs them, stores previous versions of files,
etc. That mechanism did not exist prior to Vista.
So, the only way you can reuse updates is to manually download them from
either the MS Download Center or the Microsoft Update Catalog and save
them for future use.
Sorry, but that's the way updating Vista/7 goes nowadays.
