Probably. I had a huge list of service tags that I've been collecting since 2006 and I put them in one by one, 90% didn't work and non of them unlocks any Vista or XP. Really ond service tags won't work.
Downloading anything Pre-Vista from Microsoft for free is almost impossible... It would be good if some OEMs still have them for download. Anyway, I am sure not a lot of people want to use the unsupported Vista and XP is just dying.
Now people should prioritize on Windows 7 and Office 2010 as the extended support will end soon. Who knows when Microsoft will take down all the Windows 7 downloads just like Office 2007.
I have several OEM XP iso images to share. PM for details
