This policy setting lets you specify where to find the list of websites you want opened using Enterprise Mode IE, instead of Standard mode, because of compatibility issues. Users can't edit this list. If you enable this policy setting, Internet Explorer downloads the website list from your location (HKCU or HKLM\Software\policies\Microsoft\Internet Explorer\Main\EnterpriseMode), opening all listed websites using Enterprise Mode IE. If you disable or don't configure this policy setting, Internet Explorer opens all websites using Standards mode.

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.
