I am going to be assembling a PC from parts I bought on Black Friday. I really didn't want to burn the extra money for a new windows copy. I have an old crappy laptop with one foot in the grave that happens to have windows 7, and I read online that transferring windows copies may be considered piracy. When I have assembled my PC and it boots up and stuff, how would I put the aforementioned Windows 7 copy onto the hard drive? ps: what would I do with the old laptop if I am able to transfer its windows copy?
