Buy Microsoft Windows 7
 

Hi. Most of my Ultimate Windows 7 have laptops with Microsoft Windows 7 X64 Key. They say its Windows 7 Enterprise X64t and that it is much faster than Windows Vista and Windows XP. I would like to change from Windows 7 Enterprise Activation Key to Windows 7. Does the chang affect the information and the Windows 7 Professional Generator Key found in the computer? I nee your help please!!
