Upgrade to Genuine Windows 8.1 Non-Genuine Windows 7?

Hello

I use Windows 7 genuine for these past years, and I get along fine with her. However, I do often installs own the operating system on my computer so I don't clog my computer too and make it slow. I managed to do this several times, and it worked fine - until this day.

For some reason, when I go to install the new Windows 7 OS, it says that my product key is not authentic. I don't know why this is the case, and I even tried to download the ISO image on the Microsoft Web site, does not: he just keeps telling me I entered the product key is not valid. I did so that it is the product key located on the back of my computer, and it is the same version of Windows 7 (Home Premium) that my computer came with. I'm kinda stuck with it, but I came to the conclusion that it's because I upgraded RAM 6 GB to 10 GB and product keys are related to certain specifications of the hardware in the computer, etc.. The fact that I can't download the ISO from the Microsoft Web site is somewhat confused, even if - as he asks me my specs, just for the product key, and that is to say that it is not valid.

So I think just put the scrapping of this idea and taking advantage of a student to a Windows 8.1 upgrade offer. This would be possible with a Windows 7 not genuine?

Thank you.
