In researching this particular error I came across the exact answer I was looking for at state of the tech.
method for uninstalling any Microsoft update that is applicable here. Here is the quick rundown:
1. Boot from your Windows XP CD or DVD and start the recovery console (see this Microsoft article for help with this step)
2. Type this command: CHDIR $NtUninstallKB971486$\spuninst
3. Type this command: BATCH spuninst.txt
4. Type this command: exit
The computer should restart and hopefully your problem will be fixed.
