what does windows 7 home preimium for refurbished PCs exactly mean?

You will want to check your hardware for compatibility, but in my experience, just about everything capable of running Vista has no issues running Windows 7. Windows 7 is an OS just like Vista. It won't run under Vista, so thee is no need to be compatible to run under Vista.
 


Ok. So how does the product key work then? Does it come with one?

I'm sorry but I have never heard of a refurbished OS before, I would like to know 100% for sure that this is the right version to choose or else my client will have wasted $50.
 


Lol, no I did not. It's the real me. :p

I just want conformation. I like to make absolutely sure I'm getting the right product for my client because if I do something wrong, then I might have to pay $80 myself for the regular OEM windows 7 Home.
