I have a LG combo DVD-ROM and CD writer at work, along with a LG DVD-RAM drive.
I happened to find newer firmwares for both, so I proceeded to download and install them.
After the reboot, I saw an unexpected message to the tune of ‘Windows has detected significant changes to your hardware configuration since you first installed Windows XP. You have 3 days to re-activate Windows.’
Microsoft: Does a simple firmware upgrade constitute a significant hardware upgrade?? I think not.
