I wouldn't doubt it, it's in my mind the best operating system ever. I've used Windows XP, Windows ME, OS X 10.5.6 and Snow Leopard and well Vista, Vista didn't last long, the computers in and out of the repair depot more then it's sitting on my lap turned on browsing the internet.
However, right now I'm running Windows 7 Ultimate 32-BIT on my 5-Year Old Desktop: 1.80GHz AMD Sempron and 512MB DDR Ram... It's running this better then it ran XP, multi-tasking and all. Only slows down when it's burning DVD's or CD's or reading them. Everything else runs so much smoother, it's sleeker, a lot more reliable and one of the best experiences I've ever had with a PC. Can't wait til I get my new laptop next week, Windows 7 Home Premium pre-installed, 4GB's of DDR2 Ram and a 2.1GHz AMD Athlon 64X2 Dual-Core processor.
