Windows Install disc?

Can anyone link me to a tutorial on how to create a windows install disc? I have the contents of the disc, but I need to create an install disc from them.

I just found a bunch of tutorials on how to create one from a recovery disc, but I am not using a recovery disc.

Any help is appreciated.

Op here, even better would be some way of getting around XP locking up after 30 days of not entering a key.

Its about to happen again, and I'm getting sick of reinstalling.
