I've read through pages and pages in here, and not found an answer so here's my question, in its own new topic! I've created an unattended CD for XP Pro (SP2). I often change my hardware, and hence reintstall this version often. Is there any way to activate it that can be included in an unattended cd, so that I don't have to keep phoning Microsoft everytime I format and reinstall? And pls don't mention the "copy the wpa.dbl from an activated system32 folder" method. It doesn't work. Like I said, I change my hardware often so this method can't work. But even more simply, this method doesn't work with SP2, which I have. Someone suggested editing the registry with this: ;Make the Windows XP registration with Microsoft unnecessary [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion] "RegDone"="1" Does it work? And if I connect to do updates, will Microsoft then ask me to activate anyway? I'd really appreciate any help. Thanks.
