On July 29, 2015, Microsoft launched Windows 10 to the world. It was a step in the right direction after the disaster that was Windows 8, merging the new live tile interface with the familiar Start menu design, and refocusing attention on the desktop experience for keyboard and mouse users.
Windows 10 was the OS of many firsts. It was the first to be built in the open alongside the public, with frequent technical and consumer preview builds on an almost weekly cadence, via a new program called the Windows Insider Program. Users could test and influence development as it was happening, which shaped Windows 10 in a way no previous version of Windows had been.
