Re-activate the familiar Aero interface of Windows 7 on Windows 8

As we all know, Microsoft office 2010 product key will not use Windows 7's Aero Glass interface for Windows 8. But there are ways to bring this sleek effect back.
Option 1: Use the utility available on the system
Navigate to the C: WindowsSystem32 folder (where C: is the drive that has Windows 8 product key installed) and run the WindowsAnytimeUpgradeResults.exe file. The Aero Glass effect will appear on the window title bar, but the Taskbar, the Start menu will remain the default basic interface.
Option 2: Use the Windows 8 Aero Lite Tweaker utility
Unzip and run exe executable file> click the Enable Aero Lite Glass button in the interface panel to activate.
Note: You should back up the Aero Lite theme (into C: WindowsResourcesThemes) before activating because there is no way to disable Aero Glass.
Good luck!
