Well, MS is about to end support for XP and I would like to save all the updates to install on a future system. I already have SP2 or SP3 on CD. How can I save everything after SP2/SP3 and then use them later off my external drive if/when I reinstall Windows XP? (Even if existing updates will still be available from MS, I still want to install all of them offline.) I would think this is a simple thing to do, but I have looked for the solution in the past and just resorted to installing online.
