Registry Question, I'm hoping someone knows the answer...

[Avalanche007]

Heres the long drawn out picture as to why I need this info if anyone has it... when I went to install XP, I had to reset my BIOS so it would boot from the cd (there was a problem booting from the cd rom and for some reason a BIOS reset did the trick). I did the whole installation no problem, installed all my drivers and programs. It took me about 4 hours to get everything configured... Then i installed Norton System works, this was the last piece of software I installed. And Guess what? I forgot to set my date in BIOS and after i got done installing Norton (and setting the correct date) and rebooted as norton wished, it then gave me a windows saying my one year subscription was over and I had only used it for 2 min. Does anyone know where the registry entry is that contains this original install date, if it is in fact an registry entry? I know I'm probably looking at having to do a reformat, but I want to see if anyone knows how to fix this without reformatting. Thanks in advance
