I have never used any type of torrent and I'm quite uneducated about them. I guess I just get a torrent client then search for a torrent file then create the torrent in the client. then download to a disk and use my key?
Yeah. You'll need a torrent client (just get the bitorrent one if you're unsure). Then simply google "windows _____ OEM torrent", and just enter in whatever windows version you own (NOT one you want - you aren't pirating software). Take a look at the comments on the torrent and make sure it's clean - usually people are pretty honest. Here, "clean" means it doesn't contain a virus and also doesn't contain any cracks or modifications.
Then just download it. It will probably be an ISO file, which you can burn to a CD or DVD using a media burning program. Then just use your key on the bottom of your notebook to install the software.
