TechnicalDifficulty :
Forgot to add that my case is the nzxt s340 elite, so I don't have a bay for the blue ray drive or whatever it's called, so I must install it into the USB. And BTW, I saw a video with someone skipping the product key scene, does that mean I don't have to buy the product key? (If that's what you get on Microsoft website)
Yes, you can run it Unactivated.
You lose out on a few trivial properties, and have to live with a randomly appearing nag text overlay at the bottom right.
But it does run and get updates.
You also get the satisfaction of knowing that you are not supporting the people who make the software...
