Modifying the Metro theme color

in Windows 8 is a leaked version of Windows8RTM. At present, Win8 Enterprise Edition and Windows Server 2012 have been leaked. The annoying thing is that when the system is not activated, you can't use personalized customization and other functions: The avatar can't be changed, the lock screen wallpaper can't be changed, the background pattern and background color of the Metro start screen can't be changed...

Modified example: no longer the default background color

System default start screen background color:

Unable to use personalization function in inactive:
