How to enable the hidden function in Windows 8?

Windows 8 Beta looks more like Windows 7? Actually not, some functions have been hidden due to development reasons. For example, the native PDF reader, Ribbon UI interface and camera application can actually be implemented by modifying the registry key. The following is the method:

Create a key-value "CLSID" under HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Applets\\Paint\\Capabilities

, Assign “{D3E34B21-9D75-101A-8C3D-00AA001A1652}” , then run glcnd.exe.
