Did you know Microsoft is celebrating its 50th birthday this week? The software giant was founded on April 5, 1975, and has spent the past half century achieving countless successes in both software and hardware development. The company is celebrating this milestone with a slew of big announcements, including a brand new set of anniversary wallpapers, just like they did with the recent Windows Insider Program anniversary.
The inspiration for the new wallpapers is a mix of iconic Microsoft products, such as Minesweeper, Solitaire, Mahjong, Paint, Internet Explorer, Windows, the tulip wallpaper from Windows XP, and more. As usual, each wallpaper is available in two versions: dark and light. You can also download them in the standard 16:9 aspect ratio or 21:9 if you have an ultrawide monitor.

In an announcement post on the official Windows Experience Blog, Microsoft says these wallpapers were designed by three of its designers, with help from "hardcore Windows fans":
As we celebrate Microsoft’s 50th anniversary, we’re celebrating the memories and iconic moments we’ve created over the past five decades. What better way to celebrate this milestone than with exclusive products that have made Microsoft famous than with the retro Windows wallpapers—inspired by retro colors, pixelated borders, and the anticipation of new Windows versions through the ages. Created by three Microsoft designers and Windows fans, our limited-edition wallpapers relive some of Windows’ most memorable moments.
You can download the Microsoft 50th anniversary wallpapers from the official Microsoft Design website (there are plenty of other cool wallpapers to explore).
