The leaked Windows 8 Build 7850 of M1 milestone, which is essentially a 32-bit Windows 8 Enterprise, has an expiration date of February 5th, 2011 time bomb, a day long past into history. The expiry means that installed Windows 8 Enterprise M1 cannot be activated, and is always flagged as non-genuine installation.

If you intend to use and try the very early build of Windows 8 M1, which nonetheless has already some features slated for Windows 8 available but locked away, it’s now possible to disable or remove the built-in time bomb and activate the Windows 8 Enterprise M1 edition, via the resurrected frankenbuild crack method. If you manage to activate Windows 8 properly, you can unlock and change desktop background wallpaper or theme at ease without been reverting to default on reboot.
