I'm Going for a new build and I was wondering if it's possible to use the same key in another different build?(I'm changing the motherboard too ofcourse....)Also, will I have to download windows X first to download w7 from the cd?
1 key, 1 PC. If you want to use that same key on the new machine, now the old machine has no OS.
Also, it depends on exactly what you have on the old machine. An OEM copy? If so, it is licensed to that original motherboard. You may be able to get MS to allow activation on new hardware, but they are under no obligation to do so.
"windows X" ? What do you mean by that?
