InformationThis policy setting controls whether a user may utilized guest profiles in Microsoft Edge.
The recommended state for this setting is Disabled.
In a guest profile, the browser doesn't import browsing data from existing profiles, and it deletes browsing data when all guest profiles are closed.
Deleting browser data will delete information that may be important for a computer investigation and investigators such as Computer Forensics Analysts may not be able to retrieve pertinent information to the investigation.
Users will not be able to initiate Guest mode for Microsoft Edge.
