Have you updated to Windows XP Service pack 3?

Windows update keeps telling me that the update is ready for my computer. I remember attempting before, and it seemed way more entailed than I had time for, so I cancelled it.

I like to keep things up-to-date, so it’s bugging me that this is hanging out there. I do have a bunch of questions though, if any flutherites would like to take a stab at them….

1) Any maintenance I should do beforehand?
2) Any troubleshooting tips I should be aware of?
3) Also, in your response, please let me know if you have installed this update, and any problems you ran into during the process.
