Alright, so one day i was being dumb, and decided it would be a good idea to follow one of those YouTube videos that lets you upgrade from Windows 8 to Windows 8 pro for free. I entered their given code, Windows told me it was acceptable so i went through with it. Later, it's constantly telling me that my windows isn't activated and i need to buy Windows 8 Pro. I'm just wondering what i should do? Would using Dell's system restore bring it back to it's original Product Key and make it activated again, without the Pro features?
