Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge\Extensions User Configuration\Administrative Templates\Microsoft Edge\Extensions Description
This policy controls whether the Microsoft Edge Safe Hosting component extension is installed automatically when users visit supported Microsoft services, such as Microsoft 365 Copilot app. The Microsoft Edge Safe Hosting extension provides additional security capabilities for these services. When a user accesses a supported service, the extension installs automatically to enable those protections. If you enable or don't configure this policy, the extension installs automatically and remains installed for 90 days after the user's last visit, then is removed if no further activity occurs. If you disable this policy, the extension won't install automatically. If it’s already installed, it will be removed. Note: This policy controls only automatic installation. It doesn’t prevent users from manually installing other extensions from the Microsoft Edge Add-ons website.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: EdgeSafeHostingExtensionEnabled
Enabled: EdgeSafeHostingExtensionEnabled = 1
Disabled: EdgeSafeHostingExtensionEnabled = 0
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
