I came across this while browsing Microsoft and thought it was worth posting... (Updated, thanks guys for pointing out some errors!!! Ed.)
Memory Leak Occurs with SoundBlaster Live! Device Driver (October 31, 2001)
When you use the Microsoft Windows XP device drivers for the Creative SoundBlaster Live! audio adapter, a memory leak can occur. This can cause the computer to lose system resources and run more slowly.
This problem occurs with the SoundBlaster Live! device driver that is included with Windows XP.

There is actually an update for the Live! cards on the WindowsUpdate site for the Creative SB Live! (WDM) - V. 5.1.2601.0.
But it looks like the file, Portcls.sys does not seem to be included! Looks like Microsoft are holding this update until SP1 for XP! (Come on Microsoft, release the fix, Ed.)
On another note, I did notice the existance of a new keyword :- "kbWinXPpreSP1fix", oh goodie!
