not meaning to threadjack, but I didn't see any sense in making a new thread just to ask one question: On my new laptop, it has win8.1 core. I have a win8.1 pro w/Media center key, but I had that key in use on my laptop that was stolen. Would it be possible to upgrade my 8.1 core OEM to 8.1 pro w/Media Center retail using the same key? I've never done this before, only performed clean installs with retail ISO's, and I'm not sure about this OEM stuff too much. I'd really like to purchase an upgrade key, but can't afford it at this time due to court costs. If anybody could help me with this, I'd be forever in their debt! I don't want to mess up my current install, or be stuck with a messed up system. I mean I have a factory backup on this new Lenovo, but I've never had to use anything like that before either. Any help is truly appreciated.
edit: if anyone here has a 8.1 pro key that they do not need or ever plan on using, I'd take that as well. Microsoft really made this whole thing confusing to the max! I'm hoping that they get this tangled web of a mess sorted out with 9, I really do, because I need bitlocker REALLY REALLY badly for my removable USB drives and my hard drive. That's the only reason I'm asking. I don't want to have to worry that if I get robbed again, that my data will be openly available to thugs on the street, as I have some really valuable data that I don't want anyone to get their hands on, and I know how easy it is to get a password blanker (ntpasswd, for instance).
