Three years ago I reviewed Windows 8 and time has proved skeptics right. Microsoft was unsuccessful in combining touch and desktop features in a single OS and was forced to rush an 8.1 update that made Windows more desktop-friendly and less annoying. Because of Windows' desktop dominance, however, most PCs sold since have come equipped with Windows 8, a capable if somewhat irritating OS that nobody loved. This review is largely based on my experience using Windows 10 on a desktop PC, so I've been treating Windows 10 like most computer enthusiasts will: as a direct upgrade from Windows 7/8 on my custom-built machine, just as I did with 7, Vista, XP, 2k, and other previous Windows releases. Windows 10 is the best Windows you can run today. This alone should make it a big win, not to mention the fact that it's "free." However I don't think Windows 10 is there yet. Can Windows 10 bring seamless updates that one or two years from now will make it the best, most polished desktop OS available, and still be called Windows 10? Microsoft must prove itself under this new direction. Read the complete review.
