Windows XP re-install query

[#1]

Am in the process of re-installing XP on my old laptop,  I have discs for SP1 , SP2, and SP3....
do I only need to use SP3 after the main install of the XP  ?
I don`t use it on the net much,... so not sure how it will be updated, if at all....

It will tell you, so just bung it in.  
IIRC SP2 includes SP1 but SP3 requires SP2 first.
Still plenty of XP updates around despite "end of support", certainly plenty since SP3.

OK. thanks... if it needs SP2 first then I will put that in first.... 
( I do remember SP2 also has SP1 within. )
