Question, Really Noobish

I just needed a quick question answered which is extremely dumb on my part.
I went into the Appz section because I needed XP to install on my laptop. I keep getting Windows XP SP3, which is the “Pack 3”. If I burn this to a disc will it work as xp, or is it only and update pack, meaning I still need a different copy of XP.
Basically, is it full XP or just updates?
Answer #1
its full xp. ie. its bootable.
Answer #2
it’s full, burn as a bootable disc with nero
Answer #3
its the full but the recent updates aren’t included. Just the ones that came before and with SP3
