Sp2?
 

Should I? Any reason I should or shouldn't install it?

I wouldn't install it if I were you . I'm not installing it here at least ... from what I've seen it worked well on most computers but there is about 6 pages of programs that won't work on it ... and I got told the built-in firewall was a pain in the ass most of the time .

a thread about it :
