I have an original Windows 7 Professional disk. My wife has a laptop that has Windows 7 Ultimate installed, and has a legitimate (verified) Windows OEM key. I want to do a complete reformat of the laptop, but she doesn't have her original Windows disk.
My question is, can I use my Windows 7 Pro disk to install windows back onto her machine, and then use her Windows 7 Ultimate key with it? Is it just the key that activates various different versions of Windows, or do I need to find a specific copy of WIndows 7 Ultimate?
I've tried looking around for a legit ISO of Win 7 Ultimate, but the only place I can find to download it from is the Microsoft site itself, but because my wife's Windows key is an OEM one, I can;t download it.
