I have Snappy Driver installer I use as well as Driver Booster but I agree with @JaredBusch and @scottalanmiller that for generic work PCs, most driver updates don't change anything worthwhile. Microsoft will patch most drivers over time anyways, so as long as it's not broken, why fix it?
That being said, for my personal PC, I'm fanatical about keeping my BIOS and all my drivers up-to-date. It's just how I am.
