I am building a new computer soon and have a question about operating system discs. If my friend has the discs for the Vista operating system will I be able to use his discs to put in on my new build? I would think that the discs would have some type of code that would only allow them to be on one computer at a time, or in only one house at a time but I dont know for sure. If I could use his discs that would be great because I could put that money into a better machine.
