Also my OS may not be genuine, I know that's my fault I should have read up on os installations and checked everything instead of assuming I will buy the key later on and use someone elses stuff lol (2 be fair this is my first computer i ever owned and built my self) . But I don't understand how it is illegal, because I didn't know it was a non genuine version, also currently I'm still in the trial stage so how can it be illegal, just curious about that, the question i wanted to also know is, say I have windows ultimate which is non genuine could I activate and buy the product key online? Would this process be entirely online meaning a download or updater. If I buy a different version I know I will have to do clean install but will the newly Bought be an online download or cd( I want to know because if I Need a physical disk I won't bother buying it online and waste extra time I'll just go to my local PC world store)
