This policy setting lets you decide whether employees see an additional page in Internet Explorer 11, stating that a site has been opened using Microsoft Edge with Enterprise Mode. If you enable this setting, employees see an additional page in Internet Explorer 11, stating that a site has been opened using Microsoft Edge with Enterprise Mode. If you disable or don't configure this setting, the default app behavior occurs and no additional page appears.

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.
