The Microsoft Windows 7 Ultimate THANK YOU EDITION is a rare and sought-after operating system DVD, featuring the English language version of Windows 7. It includes both the 32 and 64 bit versions. This special edition, sealed and brand new, is perfect for those looking to add to their collection of rare, Microsoft finds. I received this as a thank you gift in 2009 for being on the team that worked on the packaging for this beautiful product.
