...I dont get it. If you are picking up a 'fresh' copy of windows from a friend then it isnt a fresh copy. Are you planning on using a 'fresh' disc and then applying your windows key? Or is he providing you with a key as well along with the copy?
The reason I ask is because it should be a concern to you. If you had plans of using a hacked or a already 'registered' windows key, I would suggest not to do that. Using a already registered windows key will cause all sorts of problems on your drivers, boards, and everywhere else because you will not be able to download and install the random and periodic 'windows updates' properly.
For that reason, I opted to have my laptop to be shipped with no OS and purchased a windows 7 separately. When you purchase a computer or laptop from a store, generally it will have windows pre-installed. This means that the windows key which is labeled underneath or around the pc can only be used for that specific pc, you cannot use that same key if you decide to get a new pc say 10 years later.
Good point, I will double check tomorrow.
The last time I got one from him it was an authentic copy with an unique cd key. He's one of those guys who has a lot of computer stuff.. I'm borrowing his 300$ graphics card just because he had one lying around haha.
