This is it! The Windows RT update you have been waiting for. Or not. It is probably a bittertsweet, maybe more bitter than sweet, moment for the few Windows RT users out there on a Surface RT or Surface 2 tablet. The promised update to the OS is finally here, bringing along with it some of the update design of Windows 10, particularly the Start Menu. However, it is also formally the last major update it will receive, the long overdue proverbial nail on Windows RT's coffin.
