Prevent install of the BHO to redirect incompatible sites from Internet Explorer to Microsoft Edge
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 87, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
This setting lets you specify whether to block the installation of the Browser Helper Object (BHO) that enables redirecting incompatible sites from Internet Explorer to Microsoft Edge for sites that require a modern browser. If you enable this policy, the BHO isn't installed. If it's already installed, it will be uninstalled on the next Microsoft Edge update. If you disable or don't configure this policy, the BHO is installed. The BHO is required for incompatible site redirection to occur; however, whether redirection occurs or not is also controlled by 'RedirectSitesFromInternetExplorerRedirectMode' (Redirect incompatible sites from Internet Explorer to Microsoft Edge). For more information about this policy, see https://go.microsoft.com/fwlink/?linkid=2141715.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: RedirectSitesFromInternetExplorerPreventBHOInstall
Enabled: RedirectSitesFromInternetExplorerPreventBHOInstall = 1
Disabled: RedirectSitesFromInternetExplorerPreventBHOInstall = 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.
