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 blue-green wallpaper that is used in the leaked builds 7850, 7880, and 7899. 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 could be the earliest known build to have the start screen.

Unlike build 7746, the "Send Feedback" shortcut is missing.
