Interdire fermeture application par GPO

Question

Bonjour,

Je souhaiterais savoir s'il existe une solution par GPO pour interdire la fermeture d'une application (edge) et de ses onglets pour les utilisateurs d'une OU bien définie ?

Je souhaiterais que les utilisateurs d'une OU ne puisse pas ouvrir ni fermer les onglets edge ni fermer la page de l'application (application métier qui doit rester ouverte en permanence).

Merci d'avance pour votre aide.

Hello,

Thank you for posting question on Microsoft Windows forum!

Based on your query, Afraid that there is not a built‐in Group Policy setting that lets you “lock” Microsoft Edge so users in a specific OU cannot close tabs or the browser window. The available Edge ADMX templates let you control many aspects of the browser, such as setting default home pages, enforcing startup behavior, or even limiting installs of extensions, but they don’t extend to disabling the user’s ability to close a tab or exit the browser.

If your need is to have a business application remain open at all times, you can consider one of these alternative approaches:

1. Kiosk Mode / Assigned Access: Windows supports kiosk mode (sometimes called Assigned Access) which lets you run a specific application (such as Microsoft Edge configured to point to your business application) in a locked-down environment. This mode limits the user’s ability to interact with the system beyond what you explicitly allow. By running Edge in kiosk mode, you can bypass the issue of closing individual tabs and even the browser itself.
2. Custom Shell or Wrapper Application: For environments with strict requirements, some organizations build a custom shell or wrapper that embeds the browser or a web view and removes standard window controls (like the “close” button). However, this requires development work outside of what GPO can manage and is typically a more involved solution.
3. Third-Party Tools or Extensions: You might explore third-party applications or even custom browser extensions that could interfere with typical browser behavior (for example, by disabling the close button or intercepting keyboard shortcuts like Alt+F4). That said, enforcing such solutions via Group Policy or other centralized management tools can be challenging and may not work consistently across all user actions.

As a result, in your case, to prevent users from closing Edge or its tabs, particularly for a specific application, is to use Microsoft Edge Kiosk Mode. This mode is designed for dedicated public-facing or restricted-use scenarios, exactly like your business application requirement.

For concrete steps to implement Microsoft Edge Kiosk Mode, you can refer to the following articles.

Hope the above information is helpful!

Bonjour,

Il n'est pas possible de le faire via GPO. Vous pouvez peut-être davantage passer en mode Application Kiosque : https://learn.microsoft.com/fr-fr/windows/configuration/kiosk/

Eventuellement développer une extension Edge mais je ne sais pas comment faire.

Vous pouvez toujours trouver un logiciel tiers faisant ce que vous souhaitez.

Bien à vous,
