Windows 10 build 18947 (rs prerelease)

Windows 10 build 18947 (rs_prerelease) is a internal build of Windows 10 May 2020 Update. This build was not intended to be released but it was accidentally flighted to all insiders in all three rings on 24 July 2019.

Breaking the known insider releases routine, Microsoft managed to also release build 18946.rs_xbox_dev as well as the rs_xbox version of this build before pulling all three releases after publishing this build in all three architectures.

New features

 * This build has the new Control Center design from builds 18945, 18946 and this build's rs_xbox compile. Unlike those builds, the Notification Center only has text on it and no icons, and it also does not function. To enable it, open Registry Editor and then navigate to . Once there, create a DWORD value named UseLiteLayout. After you create it, set its value to 1.
 * The new start menu from build 18946 and the rs_xbox compile of this build is not present.
