Information
Chrome allows for processes started while the browser is open to remain running once the browser has been closed. It also allows for background apps and the current browsing session to remain active after the browser has been closed. Disabling this feature will stop all processes and background applications when the browser window is closed.
Rationale:
If this setting is enabled, vulnerable or malicious plugins, apps and processes can continue running even after Chrome has closed.
Solution
To establish the recommended configuration via Group Policy, set the following UI path to 'Disabled'.
Computer Configuration\Administrative Templates\Google\Google Chrome\Continue running background apps when Google Chrome is closed
Impact:
If this policy is set to Disabled, background mode is disabled and cannot be controlled by the user in the browser settings.
