Com 1 taken, not a problem

Had a problem where I could not free up com port. My company uses signature pads and the only way this paticular signature pad works in citrix is to set the local com port to com 1. Well com 1 was not only taken by 1 device, it was take by a 2nd (somehow). This is how I figure out what to do

I ran this as Admin using the CMD Prompt
From Start Menu type cmd into search bar right click on cmd.exe and select run as administrator
at UAC select yes to allow Windows Command Processor Program to make changes.
At the Command prompt type
Then to open device manager type
DEVMGMT.MSC (Followed by enter)
In device Manager select View / Show hidden devices
Expand Ports (COM & LPT)
Hidden ports reserved will be shown with greyed out symbol & associated manufacturer / device type
screen shot device manager ports
To re-hide non present devices in future - from an elevated Command prompt type
