Not going to happen, sorry. Once upon a time, there was a program that would download all these updates for you, but Microsoft threatened to sue them, and so the program went away.
You're going to have to download them all again, and until SP1 comes along, there's nothing you can really do to get around that. At least nothing that will save you any amount of time or effort whatsoever.
I want to format my PC and install a brand new copy of Windows. However, I'm not looking forward to the amount of time Windows 7 will take to download all the updates for the OS from Microsoft all over again!
I wanted to know where Windows stores the installation files it downloads from MS so I can simply back it up on a CD and reinstall it after the format.
Is there a way to do this?
