New system with a Asrock Z68 Pro3-M I have a Legal OEM copy of XP Home, but that might not be able to Validate, due to total system change. I was thinking of going the XP Pro way 32 bit.. But how can I activate it, from the articles on the Forums seems not possible with a Home built PC. There does not seem to be a simple program like the DAZ one, I don't wish to stuff around with Bios mods due to the MoBo being new and has a Warrantee. I still need to use XP as I have working hardware with no WIN 7 support. This will be a Dual boot system. Thanks
