Determines whether the Microsoft Root Store and built-in certificate verifier will be used to verify server certificates (obsolete)
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 109-114, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 114. If you enable this policy, Microsoft Edge performs verification of server certificates using the built-in certificate verifier with the Microsoft Root Store as the source of public trust. If you disable this policy, Microsoft Edge uses the system certificate verifier and system root certificates. If you don't configure this policy, the Microsoft Root Store or system-provided roots may be used. This policy is planned to be removed in Microsoft Edge version 121 for Android devices when support for using the platform-supplied roots is planned to be removed. This policy was removed in Microsoft Edge version 115 for Microsoft Windows and macOS, Microsoft Edge version 120 for Linux, and Microsoft Edge version 121 for Android when support for using the platform-supplied certificate verifier and roots was removed.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: MicrosoftRootStoreEnabled
Enabled: MicrosoftRootStoreEnabled = 1
Disabled: MicrosoftRootStoreEnabled = 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.
