Ok, when it comes to service packs, I'm not very knowledgeable about them. I just realized that my computer does not have one. Now I'm thinking of installing SP1, but I have some questions before I do.

First off, I want to do a series of performance scans and what not before hand so I can see the improvements (if any) my computer will make. What scans would you recommend me to do? I don't want to do like 50, maybe just 4 or 5 would be nice.

Also what do I do if all fails during or after the scan? Do I do a system restore? or insert my recovery disk?

And finally, is upgrading worth it?:P
