Don't bother with those programs. They are junk and typically full of spyware/malware. You're better off just finding your drivers from the software manufactures and downloading them yourself. And as for updating your driver, I really wouldn't bother unless you're having problems. Sometimes new drivers can cause more harm than good, and it's rare you really gain that much from them. About the only driver I'd even consider updating on a regular basis is the graphics driver. However, that's only if you game, and again, I have seen it cause worse performance.
