Invisible devices in Device Manager

In addition to the devices you can see in Control Panel, Devices or in the
Device Manager, you can also remove device drivers for devices that are
currently not physically present, by following these instructions:

1. Run this batch file.
2. Press return when the batch file pauses.
3. Check that the batch file automatically opens Device Manager.
4. Enter the command: View, Show hidden

Now you can see unconnected devices until you reboot the computer. You can, for example, uninstall their drivers.
