If the OP can get a CD from a friend, he can duplicate it and use the product key
He can borrow the disk and use his own product key. He cannot duplicate the disk. A copied disk or one burned from an image obtained by using file sharing software would violate the Microsoft EULA.
If a lady goes with you to a private place and disrobes, you can take pictures of her. If nobody knows about the caper, its lawfulness is moot. But if you post them on the Internet, you might break the law in many jurisdictions.
A poor analogy because we're not talking about antiquated local criminal statutes about lewd behaviour, nor the legality of such behaviour if nobody but the consenting participants are aware of it. Nor are we talking about public decency as a moral issue. It's about copyright and the commercial legal basis of a user's installation of Windows.
Moral: Borrow a CD and say nothing about it. And don't tell anybody I said that.
Borrow an use CD perfectly legally and tell anybody you like. Don't use file sharing applications or advise others to do it on Computerhope.
And yes, doing a torrent is extremely risky. Don't even try.
According to some research I read, among online copies shared on the web:
94% contained bypass mechanisms of Windows software product activation that could make a system unstable, 29% were completely fake, and 7% contained planted software for password and other personal data stealing. Among pirated disks in street markets in Russia, one in four had malware of some sort, and one in eight had password and data stealing trojans built-in.
