By default, Microsoft Edge leaves a background process running even after the user closes all visible browser windows. This feature, known as “Startup Boost” or “Background Mode,” is designed to keep Edge extensions active (like password managers or notification engines) and ensure the browser launches instantly the next time it’s clicked. However, in enterprise environments utilizing remote desktop services (RDS), virtual desktop infrastructure (VDI), or hardware-constrained endpoints, these lingering background processes consume unnecessary RAM and CPU cycles. Furthermore, allowing browser extensions to remain active and connected to external APIs while the user believes the application is closed can present an active security risk.
This guide explains how to completely disable ‘Continue running background apps when Microsoft Edge is closed’ via Group Policy in Microsoft Edge, forcing the browser to perform a clean, hard shutdown when exited.
Disable Background Apps via Group Policy
To enforce a strict block that prevents Edge from spawning background persistence daemons, we must deploy an administrative template. Note that this requires Windows 11 Pro, Enterprise, or Education editions.
- Log into Windows 11 with an Administrator account.
- Press the Windows Key + R to open the Run dialogue box.
- Type
gpedit.mscand press Enter to launch the Local Group Policy Editor. - In the left-hand navigation pane, strictly follow this exact path:
Computer Configuration > Administrative Templates > Microsoft Edge - In the right-hand pane, locate the policy named Continue running background apps when Microsoft Edge is closed.
- Double-click the policy to open its configuration window.
- Select the radio button next to Disabled. (By explicitly disabling this policy, we prevent Edge from utilizing the background API).
- Click Apply, then click OK.
Verify the Configuration Lockdown
Group Policy changes require the browser to read the registry upon its next launch. Close all active instances of Microsoft Edge. If you wish to force the policy update immediately across the OS, open Command Prompt as Administrator and run gpupdate /force.
To verify the restriction is active, open Microsoft Edge and navigate to Settings > System and performance. Look under the “System” header. The toggle for “Continue running background extensions and apps when Microsoft Edge is closed” will be switched off and greyed out. A briefcase icon will indicate the setting is managed by your organization. You can further verify this by closing the browser and checking the Windows Task Manager; the msedge.exe process will be completely absent from the Details tab, confirming a hard exit.
