Windows 8 build 7788

Windows 8 build 7788 is a build of Windows 8. A screenshot was leaked to the BetaWiki Discord on 5 May 2020, 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, the "Microsoft Confidential" watermark, and the blue-green wallpaper that is used in the leaked builds 7850, 7875, 7880, and 7899. If this is a real build, it might be the first build to reintroduce centered title bars which were last seen in Windows Longhorn build 4005. It could be the earliest known build to have the start screen (which will exist until 2014). This build is from the shell development lab and is therefore more similar to 7850 than the likely contemporaneous build 7791.

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