This is probably the most comprehensive review of Windows Vista that I have read so far Tom's Hardware Guide has expended some serious effort in our review of Windows Vista, to let us dig beneath the surface. We spent about 500 hours with the most current version, putting this new Windows operating system through its paces. In this review we also include more than 130 screenshots, and provide an overview of all the many different programs, settings, and functions that this new Microsoft offering delivers. Well worth a read over at Tom's Hardware
