Uninstall, change, repair buttons gone

While uninstalling a program today, I did something that resulted in me no longer having the buttons that allow one to uninstall, change, or repair a program. Does anyone have any idea what I did, or more importantly, how I fix it?

Would it be convenient to try a system restore to before the prob?

That did it. Thanks!
