Before I finally throw in the towel I would like people of the forum to tell me what they think is the correct answer to this question. It is not a question from the real test but from a practice test....

Also I will narrow this down to two answers....(one is the answer I chose and the other is the "correct" answer)

Your company wants to deploy Windows 8.1 64-bit. You need to identify upgrade paths that will allow users to keep existing Windows settings, personal files and applications.

Which PREVIOUS operating system supports this ?

Windows 7 64-bit

Windows 8 64-bit

I'm starting to doubt my own sanity at the moment !

Really appreciate folks input into this.
