For the full experience, Microsoft is inviting users to decorate their desktops with its 1985-themed wallpapers - one inspired by the first year of Windows, while the other promises a "strange summer of 1985" from Stranger Things.
"Experience 1985 nostalgia with a special edition Windows 10 PC app inspired by Windows 1.0-but one that's been taken over by the Upside Down from Stranger Things", reads the app's description.
To be honest, the entire thing looks rather disappointing, with video and effects you would have never experienced in the actual Windows 1.11.

Windows 1.11 also contains games and puzzles that bring you a fair whack of nostalgia, and also unlocks unique content from the show.
The game is more engaging than Windows 1.11, in the sense that it has actual characters, a story line and a cooperative two-player mode.
While Windows 1.11 takes you on an adventure journey, this app also treats you with clips from Stranger Things 3. They may even confront the Mind Flayer.
"It's basically the raddest show companion experience ever", Microsoft says. Among the content are mini 8-bit games that lead to clues and Easter eggs about the show.
Initial speculation was that Microsoft was going to release an open-source Windows 1.0 via GitHub, like it recently did with the Calculator app.
Microsoft explained: "The next feature update for Windows 10 (known in the Windows Insider Program as 19H2) will be a scoped set of features for select performance improvements, enterprise features and quality enhancements. If the new version is not available, you can workaround this by disabling the problematic driver in the device manager".
