After installing WinXPproSP2 I have 30 days to activate WinXPproSP2. The only cheap way for me is to do this is via internet. So I need to be connected to the internet and I really HATE this, even when the connection period is very short. My reasoning is that this activation thing has to be stored somewhere on my harddisk in a certain object, which object I don't know (registry, file, ...). Can I copy this object to a diskette or CD and copy/paste it later on an off-line installed WinXPproSP2, which would result in an activated winXPproSP2 ?
