Why this setting matters
By default, Google Chrome can keep extensions and apps running in the background even after the browser window is closed. This behaviour increases the device's attack surface — background processes can be exploited by malicious extensions or scripts without the user being aware Chrome is still active.
- Background processes can mask malicious extension activity after the browser appears to be closed.
- Disabling this reduces unnecessary resource use and keeps the device in a predictable, controlled state.
- Microsoft flags this as a direct Secure Score recommendation — enforcing it via Intune delivers a measurable score improvement.
