We recently reported about Windows 10 Build 9888 which included updated animations and context menus, changes to Settings app and more. Watch the video demo here. This build got leaked on the web and you can download it from file sharing sites. We then warned users from installing it as it is not an official build. We doubted that Microsoft might block the access to future Windows 10 builds from Build 9888. But Gabriel from Windows 10 team has confirmed that future Windows 10 update setup won’t block the upgrade from this leaked Build 9888.
You can find information to download the build here.
