I don't think you can remove it because I could not find out how.
If you got all other MS updates then you really don't need SP3.
I was reading this thread here.

Then I got the SPBlockerTools from
http://www.microsoft.com/downloads/d...displaylang=en that is posted in the thread.
I ran the SPBlockerTools and it took the icon away from the clock.
Plus when you go to MS Update and it scans for updates it will not show SP3.
Anyhow I had troubles with SP3 and it also slowed things down so I uninstalled it and the PC runs better.
Now I know I will not install it again from MS Update because it will not show up or will I see the icon by the clock about it.
