Windows 8

Windows 8 is an operating system released by Microsoft in 2012.

Wallpapers
Most of Windows 8's wallpapers were taken by Microsoft's design team, according to a UX designer who worked for Microsoft. It is the first Windows version since XP that does not credit the authors in the metadata. As a result, it is unknown who took what, with the exception of img4. The Flowers theme would later reappear in 8.1 and 10, while the Earth theme would be replaced by the Lines and colors theme in 8.1, and the Windows 10 theme in 10.

Lock Screen Wallpapers
8 came with a few built-in lock screen wallpapers, some of which came from Getty Images, while the others were created by Microsoft themselves, including graphic designer Marius Bauer. Most of these would reappear in 8.1.

At UX WEEK 2012, Jensen Harris, from the Windows design team, revealed that each of the lockscreen backgrounds was a reference to a design principle, as a sort of internal easter egg: img102 stood for "Authentically digital", img103 for "Fast and fluid", img104 for "Do more with less", and img 106 for "Pride in craftsmanship", while img101's beehive symbolizd the team's internal motto "Win as one".
