Enable security warnings for command-line flags

Supported versions

  • On Windows and macOS since 78 or later

Description

If disabled, this policy prevents security warnings from appearing when Microsoft Edge is launched with potentially dangerous command-line flags.

If enabled or unset, security warnings are displayed when these command-line flags are used to launch Microsoft Edge.

For example, the --disable-gpu-sandbox flag generates this warning: You're using an unsupported command-line flag: --disable-gpu-sandbox. This poses stability and security risks.

This policy is available only on Windows instances that are joined to a Microsoft Active Directory ___domain, joined to Microsoft Azure Active Directory, or instances that enrolled for device management. On macOS, this policy is available only on instances that are managed via MDM or joined to a ___domain via MCX.
