An anonymous reader shares a report: Microsoft developers working on Windows 8 created a puzzle and embedded it in the wallpapers used for internal builds of the operating system. The team knew that the images would leak out to the public -- and probably the internal builds of Windows -- so they decided to have some fun with it. Over the course of numerous builds, the puzzle was developed -- but only one person ever solved it! Over the weekend, Jensen Harris -- a former group program manager of Microsoft Office and Microsoft director leading the team working on the redesign of Windows 8 -- took to Twitter to come clean about the secret puzzle. He explained that it was common for internal test builds of Windows to have wallpapers that were not intended for public release, but said that messages tended to be included to discourage leaking: "Traditionally, these wallpapers included text embedded in them threatening to throw people in jail if they leaked the build, blah blah, substantial penalty for early withdrawal, not all coins go up in value (some go down!), etc. etc. We wanted to try a more elegant tact. So early in Windows 8, we created a wallpaper that was a combination of the text the lawyers wanted us to use with an attempt to appeal to people's better nature...thus the "shhh... let's not leak our hard work" series of wallpapers was born."
