Most likely it'll be best to try and re-install windows from that disc, but it erases everything on the computer's hard drive and restores it to how it would have been when you first took it out of the box. Doing that would probably be fine, but of course hard drives aren't completely safe even when you format it again, so I've heard. Its not likely to be recovered though.
I would ask the person you're selling it to and see if they want the wireless card, and if they do, also install the drivers for them. If they don't, I'd keep it so if I ever needed it for another new computer I could install it on that one.
The disc that says "applications" probably doesn't have windows on it, but its just got the extra junk that dell bundles with a new computer. If you've got a partition on your hard drive, it might be able to completely take out the stuff on the hard drive in your main partition, reformat it, and re-stall windows. depends how new it is though. On one of the computers I worked with it did, and it was called "destructive restore"
How old is the computer, and what dell model is it?
