Whenever I try to open the 'Add Hardware' function an error message saying:

'You can install only one device at a time. Another device installation is
underway, when it is finished you can try this wizard again.'

And I have no knowingly hardware being installed, does anyone know how to
overcome this??

Look in Device Manager to see if there are any yellow or red markers.
Boot into Safe Mode and look there also.... F8 while booting....
