Information
This policy setting determines whether processes from Microsoft Edge may start at Operating System sign-in and continue running once an Edge browser window is closed. This allows background apps and the current browsing session to remain active, including any session cookies. An open background process displays an icon in the system tray and can always be closed from there.
The recommended state for this setting is: Disabled.
Allowing processes from the browser to run in the background could allow a malicious script or code to continue running once the browser has been closed.
Solution
To establish the recommended configuration via configuration profiles, set the following Settings Catalog path to Disabled :
Microsoft Edge\Continue running background apps after Microsoft Edge closes
Impact:
The browser will close its processes and will not continue running as a background process.
