I'm planning on wiping my computer and simply install Windows all over again (clean install), I am already on the process of backing up all my stuff, personal files, programs, serial numbers, etc...
But I realized that over the years, Windows have downloaded a lot of hotfixes via Windows update, and I would NOT like to download all that again (mainly because my internet connection just sucks and I don't want to waste bandwidth after reinstalling Windows for something I already have).
So is there a way to backup all that updates and then simply install them? Where does Windows keep them? If I back them up, how do I "install" them again in the new clean Windows (if possible)?
I'm using Windows 7 Pro SP1, 64-bit.
