Hey guys, I am in the need of some help. Recently, I upgraded the CPU and Motherboard of my PC, which made me have to reinstall windows. I entered the product key and thought everything was fine. But then, when Windows was installed, a message popped up, telling me that the key I had entered was not valid. I tried entering it again, but with no success. This leaves me with one option; to buy Windows again.
But I have some questions. I noticed this upgrade pack that is cheaper than buying Home Premium again and gives me Professional. Would that work? I ask this because I do not want to spend 85 dollars only to have it pop up saying "Sorry, that key is not valid" or something along those lines.
Thanks in advance for you help!
