Just to be sure... "WindowsXP-to-Vista-to-7"
The article state that I can use an "upgrade" disc, but will it work if the only "full retail" license of Windows I have is Windows XP pre-servicepacks? To be clear, I have a Windows XP disc (pre-servicepacks), a Windows Vista upgrade disc, and a Windows 7 upgrade disc.
