There is no such thing as a "XP to WIn7 Upgrade disk" as any Win7 retail Upgrade disk can upgrade either XP or Vista, which don't have to be on the machine if you want to clean install the Upgrade - as you must do with XP as the qualifier anyway.
Now that you throw Anytime Upgrade into the mix, you lose me completely. Are these retail XP and Vista you are using to qualify for Upgrade, and a Win7 you Anytime Upgraded later?
I bought this upgrade pack over two years ago to upgrade my desktop from XP Pro to Windows 7. At that time, Vista didn't come into it so I have always considered it to be an XP to win 7. It tells me in the package how to upgrade from XP. On the box it tells me to backup etc. If it can be used for Vista I didn't know so I followed the same procedure this time as I did 2 years ago.
Yes, of course retail XP and vista. You need to bear in mind that I have upgraded _two_ systems in the last two weeks, one old and one new.
