Well, I can assure you, it was indeed a genuine copy. For one I don't do cracked or pirated stuff. And as I said, he worked at MS, so the copy he got from their company store was the real thing.
When you say I have to buy a Retail Version(that was indeed, and is indeed what I am going to do). I just want to be sure that I buy the right one. As it says "Windows 7 Upgrade", it just makes me pause b'c, well I never owned Win7 to begin with so how can it be an upgrade?
I will tell you now, as it may come across from my posts, I'm not a PC Savvy person, which is why I felt it best to ask those "in the know". So if you could shed a bit of light on that area of the question I would be greatly obliged. Thank you.
