How to remove multiple devices in bulk / all at once

Hi,

I am able to locate several unused com ports by following method :-

cmd.exe
set devmgr_show_nonpresent_devices=1
start devmgmt.msc
click on show hidden devices.

The unused devices are slightly greyed out, and I am able to delete one at a time.However, as I intend to remove like 50 or 100 devices(com ports) I am looking for a way where I can multi select all devices and hit delete for once, instead of deleting one at a time, and than waiting for device manager to refresh.

Thanks in advance
