What to do after XP install?

I just did a clean install of XP and all devices are set up with correct drivers.

I then downloaded the security and other updates from Microsoft Update.

Is there any other fixes I need? I remember reading somewhere about an ASPI fix for XP, among other things, but can't find them.

--------

time to tweak it.

there are many guides out there.

tweakxp has hundreds of little tweaks and fixes.
