How to configure "-incognito" for default apps on Windows 10?

Solution 1:

Changing this registry option works for me when chrome is set to the default browser

[HKEY_CLASSES_ROOT\ChromeHTML\shell\open\command]
From: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -- "%1"
To: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --incognito -- "%1"
