It could be important if you suspect that a device driver is causing problems.

About once each decade I've had to remove such errant device drivers to fix a Windows PC problem. But I've never bothered with "cleaning" device drivers that are not currently used because most of those drivers are for removable USB devices that will probably be reconnected and therefore reinstalled again.

You can manually uninstall unused drivers but by default Device Manager does not show all installed device drivers.

1. Show non-present devices by adding the environment variable
Through the GUI https://www.thewindowsclub.com/how-t...s-in-windows-7
Through the commandline https://www.thewindowsclub.com/show-...evices-windows

2. Show Device Manager's hidden devices

3. Uninstall unused devices
