My windows vista after tweaked, is fine. All you vista haters always have made me laugh.
It has been proven time and time again, that it runs just fine for people with a brain. I have a windows 7 Pc with darn near the same system specs as the vista, and the benchmarks are very, very close.
Windows 7, has been, and was showed to be vista service pack 2. If you tweak what runs, and arnt a retard. It's a great OS. Never had a BSOD, no bad drivers, nodda.
