Windows 10 build 18947 (rs xbox)

Windows 10 build 18947 (rs_xbox) is an internal build of Windows 10 May 2020 Update. This build was accidentally flighted to all insiders in all three rings on 24 July 2019. It is currently the only publicly available build of the  branch.

Breaking the known insider releases routine, Microsoft managed to also release build 18947 (rs_prerelease) as well as build 18946 (rs_xbox_dev) before pulling all three releases after publishing the AMD64 variant of this build within five minutes.

They also broke the UX routine and showed up with some new major changes.

New features

 * Fully redesigned Start menu. It was intended to be used in the Windows 10X (later became Windows 11) operating system. It works properly only with the Light theme.
 * This build has the new Control Center design from builds 18945 and 18946. Unlike those builds, the Notification Center only has text on it and no icons, and it also does not function.

Enabling the new features

 * To enable the new Start menu, download mach2, then run an elevated command prompt session and type in.
 * To enable the new Control Center, navigate to  on Registry Editor, then create a DWORD value named   and set its value to 1.
