Software\Policies\Microsoft\Edge Value name: NativeMessagingUserLevelHosts
Enabled: NativeMessagingUserLevelHosts = 1
Disabled: NativeMessagingUserLevelHosts = 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.
