I think this is a silly question... Besides the time spent downloading and updating, is there any difference between installing Windows 7 with no SP1 (and doing the billion updates) versus installing a copy of Windows 7 with SP1 already on the disc? I.e. will you end up with exactly the same result?
I have a pre-SP1 copy of Windows 7 Pro from years ago that I'm going to put on a new build but I'm wondering if there is any benefit to getting a new copy with SP1.
