I hope that my title isn't going to throw you off. but i was wondering if anyone else has this problem and how can i fix it.

i have windows xp sp2(is there an update for that? i read something about sp3) and i want to view my file extensions. like for example one of my pictures is "lol.jpg". however, when i click on it, i only see "lol" and i want to see "lol.jpg".

so i follow the steps i've read online. i go to my computer. click tools, then folder options, then view. only to find out that i can't change it. there isn't a checkbox or anything. i tried double clicking and that doesn't help. since maybe it'd be easier if i included a picture:

if anyone can help me, thank you so much!
