Upgrading to SP1 Help

[same]

Hi. I have installed on my computer a vlited vista ultimate x64. I do not want to have have to make a new slipstreamed SP1 os and reinstall the whole thing losing all my drivers, installed games, etc.

So my question is: is there any way to get SP1 on my system short of doing the above?

I don't think so...Perform Clean install without vLited disc.

Hmm. ****. I guess I will create a new version of my OS with SP1 slipstreamed, and just reinstall my games and stuff. Should only take a few hours, just didn't want to have to do it again since i've installed at least 30 os's this month.
