Problem autostart V18 upd3 and close Edge button

Hi everybody,

1/ I use wincc unified v18 update3 on a Windows 10 IOT 21H2. When I put a runtime shortcut in the Windows startup folder, the runtime does not launch. And this even if the runtime is checked with administrator rights. I have to launch it manualy.

2/ In the Runtime software I activate autostart but the project icon remains yellow and the application freezes. Do you have any idea to make the autostart function work?

3/ How to make a simple button that allows you to exit the Edge browser? I tried using a batch file with a taskkill which works when I launch it manually but when it is launched by wincc it does not execute the taskkill function although it manages to execute a writing function in a text file . do you have an idea? 

Good morning,
Thanks for taking time to respond to me.

1/ I use the Windows folder in which we put the programs that should launch
at startup. shell:startup When restarting the PC I do not see the runtime
running automatically (no runtime popup) and I cannot find the runtime in
the task manager either.

Solved:

    After regenerating the certificate then reloading the program and loading the web page from localhost instead of the IP address it works.

2/ I did another test. just enable autostart in the runtime software and
restart the PC. it doesn't work either, the project activates the yellow
icon and freezes without doing anything else.

Solved: see 1/

3/ I have a PC on which I run the runtime. The screen is touchscreen and
the customer will not have a keyboard or mouse. Edge is launched in kiosk
mode. I want to add a button to exit Edge and return to the Windows
desktop. I created a batch file with: taskkill /f /im msedge.exe
which should run when the button is pressed. the problem is that the
runtime does not have permission to execute the taskkill command.

I try to find an solution with script powerswhell .PS1
