If you find that some of your newly installed devices are not working correctly or in fact your Windows computer freezes frequently, you might want to consider removing old & unused device drivers in Windows 10/8/7.
Remove Old Drivers on Windows PC
To remove old and unused drivers from your Windows computer, first open Start Menu and right-click on Computer and select Properties. From the left side panel, click on Advanced system settings and click on Environment Variables. Alternatively, simply open Control Panel and type Environment Variables.
Now under the User variables box, click on New and type-
in the Variable Name text box & 1 in the Variable Value box. This will set a flag to allow you to now view unused devices.
You can also use this method to show non-present drivers.
Now type devmgmt.msc in start search and hit Enter to open the Device Manager.
Click View tab and select Show hidden devices. Expand the branches in the device tree & look for the faded icons. These indicate unused device drivers.
Right-click on it and select Uninstall.
