Microsoft is celebrating its 50th anniversary by inviting fans to reminisce and has released a collection of exclusive products, including limited-edition Windows wallpapers designed by Microsoft designers and Windows enthusiasts. These wallpapers reimagine iconic moments in Windows history, featuring the four-square logo and inspired by nostalgic elements such as the Windows 95 startup screen and classic games like Mahjong and Solitaire. Designer You Zhang created wallpapers that merge retro and modern styles, while art director Yulia Makhmudova designed a wallpaper featuring Solitaire cards arranged in the shape of "50" and revisited the iconic Tulips motif from Windows XP, adding 50 yellow buds. More ways to celebrate the anniversary can be found on Microsoft Unlocked.
