If you have installed and activated early builds of Windows 8, such as Windows 8 M1 Build 7850 or Windows 8 M2 (Pre-M3) Build 8955, you must be disappointed that the very early Windows 8 build is strikingly similar to Windows 7, with probably only an extra UserTile sitting on the notification area of the Windows Taskbar been visibly noticeable. However, there are in fact several new and useful features and enhancements that been added to these Windows 8 early builds, but the features are hidden and locked to make it a secret and hidden from leaking, or until the features get tested for stability and reliability.

Nonetheless, some of the Windows 8 features can be unlocked and enabled through simple registry key hacks. Here is a few locked Windows 8 features that can be unlocked and made active via registry hacks. Most of the trick involves adding or editing of registry keys, thus use Registry Editor (RegEdit) to perform the hacks related to registry keys.
