and remove unused devices. To do this, right-click on
'My Computer' or 'Computer' and open the 'Properties'

and klick on 'ENVIRONMENT VARIABLES'. Now select
the lower part (NEW ENVIRONMENT VARIABLE). At
'NAME OF VARIABLES' enter the following text:
devmgr_show_nonpresent_devices
Enter the value '1' in 'Value of Variables'. Confirm the en-
try with 'OK' and restart the computer. After rebooting
open the Device Manager. Select the menu item VIEW
and activate the option 'Show Hidden Devices'. The
'Ghost Devices' previously hidden are now displayed in
grey. Check for entries in the different categories such
as USB, storage volumes, etc. Only delete the entries of
devices you no longer use from the 'Device Manager'.
