I'm not sure what you mean by restoring the CD burner, it can't in a software sense. The native XP utility is best tested by inserting a blank cd, if your autoplay is normal it'll show a prompt asking what you wanna do with it. Select "open a writable folder." Dump a small amount of files in that writable folder, about 50MB of stuff is good. Then just hit the "write cd" on the upper left or something like that. If autoplay isn't on as in you don't get a prompt upon a blank CD insertion; after inserting the blank CD wait for about 15 seconds. Navigate to that optical drive then dump files into it, try burning....
