How to choose which application Chrome uses for deep links (e.g. when zoom:823948290348 is typed into Chrome's URI bar)?

I have managed to change on my computer the application that is used for Zoom by changing the registry command that launches it:

  • Run regedit
  • Navigate to the key HKEY_CURRENT_USER\SOFTWARE\Classes\zoommtg\shell\open\command
  • Double-click the (Default) key, save its current value as backup, and change the value to
    "C:\path\to\your\application.exe" "--url=%1"

Change the parameter of the above command to suite the application that you are calling.

(This works in my environment and for my browser. I have no idea if this will work for you.)
