do your regular windows updates and sometimes they include hardware driver updates. yes updating drivers is easy but it requires some basic knowledge
of how to put it back to the old version in case you have a problem. if you don't feel comfortable then don't do it, stick with your windows
updates. only update drivers if you feel like you are having some sort of issue.
if you happen to know someone with IT experience then go ahead and update them yourself, it's good to have someone handy in case there is a problem.
