-- Posted by Brawler at 2:22 am on Aug. 16, 2008 I got a new computer, and i got some software discs for it, they're already pre-installed, so they're just for backup, but i have a question. On the paper sleeve, there are some numbers: (example.) US-0t987-89723ryhuiws-67g-98765 now, do i need that number? or can i just toss the case? because id rather put the CD in a CD holder as opposed to having it loose. -- Posted by VIPMeezy at 2:26 am on Aug. 16, 2008 keeping it is maybe the best answer ? -- Posted by verl mcverl at 2:26 am on Aug. 16, 2008 the number is probably a serial number, keep it in case your computer messes up -- Posted by Naptime at 3:30 am on Aug. 18, 2008 Always keep numbers like that. You never know what they mean (they're probably manufacturer part numbers). Just cut them out, and stick them to the new case witha bit of stickytape.
