Uninstall hidden devices

To get rid of that unwanted driver/device: 1) Open the "Start" menu and choose "Run…" 2) Type in "cmd" (without the quotes) and click "ok". 3) At the cmd prompt, type in "set devmgr_show_nonpresent_devices=1" (without the quotes) and press enter. 4) On the next cmd prompt line, type in "devmgmt.msc" (without the quotes) and press enter. 5) In the Device Manager Console, from the "View" menu, select "Show Hidden Devices". Now, as you expand the different drivers and devices in device manager you will see not only the items that Windows currently detects as installed on your pc (these are the usual items displayed), but you will also see drivers, devices, and services which have been loaded in the past but were not uninstalled or are not currently started. You can find your offending device, right-click, and choose “uninstall” to remove it from the system completely. Be careful though; you should note that non-loaded devices, drivers, and services are “grayed” out, but that doesn’t necessarily mean that you should delete all of them. Only remove items you know you don’t need.
