>*Default setting: Disabled or not configured (Allowed)* [!INCLUDE [prevent-turning-off-required-extensions-shortdesc](../shortdesc/prevent-turning-off-required-extensions-shortdesc.md)] ### Supported values | Group Policy | Description | |---------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Disabled or not configured
**(default)** | Allowed. Users can uninstall extensions. If you previously enabled this policy and you decide to disable it, the list of extension PFNs defined in this policy get ignored. | | Enabled | Provide a semi-colon delimited list of extension PFNs. For example, adding the following OneNote Web Clipper and Office extension prevents users from turning it off:

*Microsoft.OneNoteWebClipper8wekyb3d8bbwe;Microsoft.OfficeOnline8wekyb3d8bbwe*

After defining the list of extensions, you deploy them through any available enterprise deployment channel, such as Microsoft Intune.

Removing extensions from the list does not uninstall the extension from the user’s computer automatically. To uninstall the extension, use any available enterprise deployment channel. If you enable the [Allow Developer Tools](../group-policies/developer-settings-gp.md#allow-developer-tools) policy, then this policy does not prevent users from debugging and altering the logic on an extension. | --- ### ADMX info and settings #### ADMX info - **GP English name:** Prevent turning off required extensions - **GP name:** PreventTurningOffRequiredExtensions - **GP path:** Windows Components/Microsoft Edge - **GP ADMX file name:** MicrosoftEdge.admx #### MDM settings - **MDM name:** [Experience/PreventTurningOffRequiredExtensions](https://docs.microsoft.com/windows/client-management/mdm/policy-csp-browser#browser-preventturningoffrequiredextensions) - **Supported devices:** Desktop - **URI full path:** ./Vendor/MSFT/Policy/Config/Browser/PreventTurningOffRequiredExtensions - **Data type:** String #### Registry settings - **Path:** HKLM\Software\Policies\Microsoft\MicrosoftEdge\Extensions - **Value name:** PreventTurningOffRequiredExtensions - **Value type:** REG_SZ ### Related policies [Allow Developer Tools](../available-policies.md#allow-developer-tools): [!INCLUDE [allow-developer-tools-shortdesc](../shortdesc/allow-developer-tools-shortdesc.md)] ### Related topics - [Find a package family name (PFN) for per-app VPN](https://docs.microsoft.com/sccm/protect/deploy-use/find-a-pfn-for-per-app-vpn): There are two ways to find a PFN so that you can configure a per-app VPN. - [How to manage apps you purchased from the Microsoft Store for Business with Microsoft Intune](https://docs.microsoft.com/intune/windows-store-for-business): The Microsoft Store for Business gives you a place to find and purchase apps for your organization, individually, or in volume.
