I recently upgraded my computer (New motherboard, cpu, ram, etc. ). I tried switching my hard drive over from the old machine to the new one and running a repair installation of Windows XP Pro. Everything seems to work fine, but it tells me that I need to activate windows and only have 3 days to do so. When I click on Activate windows (or run oobe/msoobe /a) from the Run window, the machine thinks for a second, but doesn't start the activation window. This is a non-OEM version of XP. Can anyone help?
