How do you stop apps from auto starting on startup?

[macx]

There are a number of applications I'd just as soon didn't start
when I startup the computer.

How do I stop them from loading or starting automatically on startup?

They're not pinned to the start menu.

I don't want to delete them, just not have them start automatically
when I start up.

Thanks!

Oh - XP Home

Run msconfig and check its startup tab for applications.
