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.

A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article and should be applied only to systems experiencing this specific problem. This fix may receive additional testing at a later time, to further ensure product quality. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Windows XP service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, please go to the following address on the World Wide Web: http://support.microsoft.com/directory/overview.asp

   29-Aug-2001   15:58   5.1.2600.10   132,864   Portcls.sys   

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!


If you use NTFS your data will be protected and your system will be a bit faster but some strange things may occur.

For example, if you are brave enough to swap your motherboard and change it with another, your system will just halt. It will start to load and fail straight away. You can't even run it under safe mode since it will halt trying to find some files from the SYSTEM32 folder.

All your data will be unavailable since NTFS gives this protection until you reinstall XP system again. To give you idea how painful this is on an AMD Athlon 1400 with 256MB of memory, that's a 45 minute trek at least.

So when you install your XP and want to change your board, get ready to install Windows again.
