Microsoft is celebrating its 50th anniversary this week, and it’s offering some new Windows wallpapers to mark the occasion.

Rainmeter is one of the best fits for your Windows PC. Although the app doesn’t offer any live wallpaper, it has a library full of wallpaper that you can customize according to your preference.

Windows has had a long history since its inception nearly 40 years ago, and for almost as long, it has offered a selection of wallpapers to choose from so you can decorate your desktop.
