Bill Gates and Paul Allen founded Microsoft 50 years ago on April 4th, 1975. While the two may have had ambitions, they probably did not imagine how successful of a company Microsoft would become in the decades that followed.

To celebrate its anniversary, Microsoft has released a batch of wallpapers for its Windows operating system and some other goodies.

Tip: You can click on this link to download the wallpapers as a ZIP archive to your system. The archive has a size of 24 megabytes and contains eight images in black and light variants each.

Microsoft has this to say about the release: "As we look ahead to Microsoft’s 50th anniversary, we’re celebrating the iconic memories and moments you’ve made over the past five decades. What better way to celebrate than with exclusive products like nostalgic Windows wallpapers—channeling the retro colors, pixelated edges and anticipation of new Windows releases across time. Made by three Microsoft designers and Windows superfans, our limited-edition wallpapers reimagine Windows’ most memorable moments."

Here is a preview of what you find inside.

You get two Windows logo, Microsoft Mahjong, Cascading Solitaire, and Yellow Tullips wallpapers in the pack. These come in light and dark variants, and two different sizes, which means that their are suitable for dark and light desktop schemes.

As far as the resolutions are concerned, the wallpapers are available as 3840 x 2160 and 3440 x  1400 pixel images.

Some look rather basic, as they just display 50 using Mahjong tiles or Solitaire cards. Die-hard players may still find these interesting.

The Windows logo wallpaper is probably the most interesting one, as it references several symbolic programs, features, or services. There is Clippy, Internet Explorer, or an Xbox Controller among many others.  Last but not least, there is the tulip wallpaper that users flowers to display the number 50.

More than just wallpapers
