Genuine Microsoft Windows Vista Ultimate Upgrade Version 64 Bit W/Product Key

Upgrade your Windows 2000 professional, Windows XP or Windows Vista to Windows Vista Ultimate.  I purchased this upgrade kit 5+ years ago. 

When installing, a message will appear that states the key has already been used.  A code will appear and ask how you would like to register.  Select by phone.  When you call the automated number enter the supplied code.  Microsoft will then give you a new code that you enter into your computer to complete the install.

Includes: 64 bit DVD Disc, Case, Instructions, and Product Key.
