Can I use a Ultimate W7 key with Home Professional disc
I have an HP desktop which came with Vista. I qualified for the WIndows 7 Home professional upgrade which I installed on it.
I am now building another rig and want to purchase a W7 Ultimate (or anything other than home) serial key which does NOT come with the disc.
Can I use the HP W7 upgrade disc to install on my new PC with an Ultimate key that I purchased from ebay?
