Which old utility do you still keep installed?

I keep finding useful little utilities that do one job properly. What is the one program you install on every machine?

winamp. it's the only thing that plays all my mp3s without complaining. and it skins, which is cool. that's it, nothing else gets to stay.

lol winamp. it's 2003 and you're still using that relic. try foobar2000 if you want something that doesn't look like a toy.

lol foobar2000? never heard of it. winamp does the job fine, why fix what ain't broken. maybe if you're some audio nerd who needs 1000 plugins, but for playing mp3s while i frag, it's perfect.

lol foobar2000 is for audio nerds who want to tweak every setting. winamp is simple and it works, why bother with something that looks like a command prompt. and yeah 404notfound, calling it a relic is harsh, it still plays my mp3s fine

lol 404notfound foobar2000 looks like a command prompt, who wants that. winamp has skins and it just works, no need to tweak every little setting.

lol darkangel 'it just works' is what people say when they can't handle real software. winamp is for people who are scared of options. foobar2000 is for people who actually want to control their music.
