Hi, GObonzo
Welcome to the Microsoft Community.
You can try to uninstall the widget with the command. The advantage of uninstalling is to prevent the widget from sometimes starting the WebView and continuing to occupy resources when you are not using it.
Right-click on the start menu and select Terminal. If you don't have a terminal installed, you can directly search for the command prompt to open it, then copy the following command and press Enter.
winget uninstall MicrosoftWindows.Client.WebExperience_cw5n1h2txyewy
I'm not sure if this will meet your needs, if not, please keep replying to me.
Best regards
