Hello, my computer says all of my Drivers are up to date. Why then, does CCleaner show me that I need to update one or more?
Sometimes/often there wiil be newer versions of drivers than the one that you have installed.
You don't always need that new version, and Microsoft doesn't think that you do so isn't updating it.
Updating a driver may help something work better for you, it may not change anything for you, sometimes it may actually stop something from working properly.
It's your choice but personally I would never update a driver unless I am seeing a problem - a problem that might be being caused by having an 'older' driver.
