Description
Enabling Guest mode allows the use of guest profiles in Microsoft Edge. In a guest profile, the browser does not import browsing data from existing profiles, and it deletes browsing data when all guest profiles are closed. If this policy is enabled or not configured, Microsoft Edge lets users browse in guest profiles. If this policy is disabled, Microsoft Edge does not let users browse in guest profiles.
