Pros: There is so much good about Windows 7. It installs easily, it runs stable with none of the problems that were in Vista. Considering how complicated the app environment has become, this OS is a really amazing thing.
Cons: Windows Update needs an overhaul. There are too many updates and too many that require a reboot. When you buy this version with SP1, you still have to download a boatload of patches and updates to get up to date. MS need to figure out a better way to update their OS.
Summary: I purchased this Microsoft Windows 7 Home Premium SP1 32BIT English OEM version which has all most all the features of pro version. Vista was bad and Windows 8 is not very useful for a desktop. no complaints so far.
