Use one, and you won't need to deal with Device Manager so much, nor will you need to go find the right driver from your hardware maker yourself.
Driver Booster can be scheduled to automatically find outdated drivers.
This means you can use something like an external hard drive to transport and install the downloaded drivers to any other computer.
When you need to update a driver, you can see the full information on what the new driver details are versus the currently installed driver.
You can see the version number, manufacturer, INF file name and date, and hardware ID.
