Yeah, the opt-in or opt-out stuff sucks, but imgburn rocks! Coupled with ISO Recorder from Alex Feinman
http://isorecorder.alexfeinman.com/isorecorder.htm, it's a great set of CD ripping and burning tools for free.
Ain't nothin' better than being able to insert a CD/DVD, right-click the drive and click create ISO, then burn the ISO at anytime with Imgburn.
I use those two for every Dell OS CD/DVD that I see so that I have them when someone brings me a computer to rebuild.
Nowadays, there's a lot. Vista home, premium, business, ultimate, 32 bit, 64 bit, win 7 home, premium, pro, enterprise, SP1, SP2, SP3, etc. etc. etc. It's always good to have a copy on hand!
