My in-laws old Dell is starting to give up and I'm planning on building a new budget PC. I'm thinking it would be great if I could use the version of XP they have on disc that came with the DELL and use the license that came with it. Am I going to be able to do this? I have another version non-Dell version of XP with sp2 slipstremed into it, could I use that to install and then use the old Dells license for it? I'm not sure how the Dell licensing works. Any suggestions?
