Well to use the "app-id" argument, you have to specify the default "user-data-dir" of your Chrome! (in my case: "C:\Users\***\AppData\Local\Microsoft\Edge\User Data")

I got something: It has to be something with the 1000 arguments given at "Launching msedge". Until argument "--disable-popup-blocking" it starts well with "Run" from Windows. I have to find the bad argument. Give me some minutes.

Thanks for very quick response! Unfortunately, Webdriver accepts the code, but the output doesn't work... I just see the normal Chrome (Microsoft Edge) window, as I start it without the "app-id" argument. Any ideas? $sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"ms:edgeOptions": {"args":["app-id=mkjkjhffnfhefonpoajpeaohoocodfig"], "w3c": true, "useAutomationExtension": false}}}}' Output of chrome.log-File:

Is it possible to start the Browser in 'application mode'? (with argument --app, or --app-id xxxx) For example, I have a web application, similar WhatsApp Web. I added this Website to "Apps" in Chrome. So I have a separate Icon in the task list, which is very helpful. Now I would like to start this "Application" (which is actually a normal website) with AutoIt and Webdriver, so i can automate the login process afterwards. Many thanks!
