Information
This policy setting prevents Microsoft Edge from showing security warnings that potentially dangerous command-line flags are in use at its' launch.
The recommended state of this setting is 'Enabled'.
Rationale:
If Microsoft Edge is being launched with potentially dangerous flags this information should be exposed to the user as a warning, if not the user may be unintentionally using non-secure settings and be exposed to security flaws.
Impact:
None - this is the default behavior.
Solution
To establish the recommended configuration via GP, set the following UI path to Enabled
Computer Configuration\Policies\Administrative Templates\Microsoft Edge\Enable security warnings for command-line flags
Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MSEdge.admx/adml that can be downloaded from Microsoft here.
Default Value:
Enabled.
