About XP 32 bit sp3 and sp2.

If you have XP 32 bit SP3 can you install something that is meant for XP 32 bit SP2? (or does it matter?)
OR, do you use the universal window installer?
I have heard yays and nays about it?

If you ask because of the system requirements for example CIS.

XP SP2 is a minimum requirement. So SP3 is going to work.

Is that the gist?


That is exactly it!!! :-TU
Thank you much!!!
