My computer was risen from the dead, what do I need to update?
 

I just fixed my laptop that had some messed up host files and could not get the internet for 2 years. I will start using it more, instead of relying on my work laptop.

What updates do I need to make to it from the last few years it was retired? I know several security changes have taken place in many programs. It is a windows machine with XP Home and that is pretty out of date. I can update those and my IE. Anything other suggestions?

Get the latest FireFox and XP SP2 if you don't already have it.

Firefox 2.0
XP Sp2 if you don't have it
