I just ordered a retail copy of Windows 7 Professional Upgrade to finally upgrade my work computer from Vista.
It's not scheduled to be delivered until Monday, though, and I was hoping to take my computer home and upgrade over the weekend. I already have a full retail (non-upgrade) disc for the same edition that I'd bought for myself, though.
So can I use that disc to perform the install, and then just enter my upgrade key on Monday when it comes in? Will that make everything activate properly? Or do I need to wait till I get my actual upgrade-specific disc before I try to use my upgrade-specific key?
