I'd think twice about applying these patches.
I used to apply new patches religiously, then I hit that well publicised buggy patch that slowed the entire system down by 10x. Applying the fixed fix made no difference, and now even today, almost 1 year on, my Athlon 2800XP is less responsive than an Amiga 600.
Before you apply a patch - wait a while, then do a search with the patch number on the net for any problems.
