Actually, you would have to uninstall Windows 10, 8.1, 8, 7, Vista - every version of Windows later than XP as Microsoft pushed this "update" retroactively to all OS's that had not been end-of-lifed by June of 2015 or thereabouts.
Once again, this is not about existing users - we don't count in Microsoft's estimation. It is about corporate warfare with Rovi (the current incarnation of Macrovision, or at least ancestor / inheritor of Macrovision technology, patents, royalties etc.). If you look, many of the cable and satellite set-top boxes in the western world and a good deal of south-east Asia run Rovi software which **** Microsoft off to no end. It thwarted their ridiculous goal to be the monopolistic owner of the set-top-box and over-the-top content delivery mechanisms and systems. The fact that ChromeTV and all the other content delivery devices / services have long since pre-empted that goal is lost on Microsoft, and out of pure spite they will do whatever it takes to make sure Windows users are precluded from access to products provided by its sworn corporate enemies (Rovi, Google, Apple to name a few). And don't forget the game console wars. In Micorosft's mind, if you want to play games, get an Xbox - your computer is no longer going to be allowed to play any game that is adware free, even if you did pay for a "perpetual license" on the Windows PC platform.
