Microsoft set the internet abuzz last week when it made a cryptic announcement about the "all-new" Windows 1.0 -- and now we know why. As we'd already speculated, it's all about Stranger Things. To celebrate the return of the show -- set in 1985, Microsoft's banner year -- the company is launching the Windows 1.11 app. It features classic Paint and Terminal programs, as well as Stranger Things-themed puzzles and exclusive content. No floppy disk required.
