Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 80-84, 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OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 84. This policy doesn't work because this policy allowed these features to be selectively re-enabled until Microsoft Edge version 85. The Web Components v0 APIs (Shadow DOM v0, Custom Elements v0, and HTML Imports) were deprecated in 2018, and are disabled by default starting in Microsoft Edge version 80. If you set this policy to True, the Web Components v0 features are enabled for all sites. If you set this policy to False or don't set this policy, the Web Components v0 features are disabled by default, starting in Microsoft Edge version 80.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: WebComponentsV0Enabled
Enabled: WebComponentsV0Enabled = 1
Disabled: WebComponentsV0Enabled = 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.
