I am extremely pleased with Windows 7 64 bit. With the right hardware, it is, if one disregards the endless power-up, very fast and stable. I can since Windows 7 64 bit really do not remember when I have the "blue screen" last seen. The operating system is also wonderfully colorful and easy to use. I just wish that Microsoft finally gets to the number that Windows boots up in 30 seconds. My father has a five-year old Intel-Mac first-generation load (no 64 bit and Co.) and always the latest Mac OS X, just 2GB of RAM while the device starts up in 30 seconds, come what may. Why not create the Windows today?
