Windows 8 build 7788

Windows 8 build 7788 is a Milestone 1 build of Windows 8. A screenshot was leaked to the BetaWiki Discord on 2020-05-05, but the image was deleted soon afterwards. This build is the first known build to have the Modern Task Manager, the Modern Reader, the Ribbon Explorer and the 7850 wallpaper. If this is a real build, it might be the first build to reintroduce centered title bars which was last seen in Windows Longhorn build 4005. It is also the earliest known build to have the start screen.
