I need a full installation disk for Windows XP, but I want a legal one so I can install WGA and whatnot. I am developing software for my job, and they let me work from home, but only if I supply the needed hardware/software. One of the requirements means I have to test on Windows XP/IE, so I need a legal XP (full installation, not upgrade) disk to run inside my VM. Any suggestions, or do I have to suck it up and buy the full version at Wal-mart or something?
