About 10 months ago I created a Windows XP SP2 integrated CD for Dell systems using nLite. How does the Product Key work for Dell systems? I've been using a copy of a Dell Windows XP Home CD with SP2 integrated using nLite to reinstall XP Home and many different Dell Dimension desktop machines. I've never noticed any issues with XP product keys by doing this. It installs fine on all those machines, never asks for a product key, and passes the Windows Geniune Advantage tests. So I never had cause for concern. Now I'm concerned. I've never fully understood how the Dell CDs work. I thought there was some kind of BIOS check it did and if it was being installed on a Dell PC that had come with XP it was OK. When tried on an older Dell that shipped with ME, for example, it wouldn't work. I've been able to install from that disk to an HP but was prompted for a product key. Now I've noticed that there is a product key on the disk (winnt.sif) and it's ending up on all those PCs. If I have been a total id*** and screwed up a bunch of computers, go easy on me please. So, how do I make a CD where I don't have to worry about the product key? I could remove it from the CD? Leave it and manually enter it from the sticker after install using Magic Jellybean? Leave it because the individual product key is not that important? I'll be using a current Dell CD with SP2 "from the factory" and integrating the hotfixes using RyanVM's download and nLite.
