Control the User-Agent Client Hints GREASE Update feature (obsolete)
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 102-133, 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OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 133. The User-Agent GREASE specification recommends the inclusion of more GREASE characters beyond the current semicolon and space, and recommends that the arbitrary version number is varied over time. When enabled, the User-Agent Client Hints GREASE Update feature aligns the User-Agent GREASE algorithm with the latest version from the specification. The updated specification can break some websites that restrict the characters that requests may contain. For more information, see the following specification: https://wicg.github.io/ua-client-hints/#grease If this policy is enabled or not configured, the User-Agent GREASE algorithm from the specification is used. If the policy is disabled, the prior User-Agent GREASE algorithm is used. This policy will be obsolete after version 133 because the updated GREASE algorithm is on by default since Microsoft Edge version 102.

Enabled: UserAgentClientHintsGREASEUpdateEnabled = 1
Disabled: UserAgentClientHintsGREASEUpdateEnabled = 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.
