Description

OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 144.

The User-Agent HTTP request header has been reduced by default since Microsoft Edge version 119. To continue receiving detailed platform information, migrate to User-Agent Client Hints, which replace the deprecated detailed User-Agent header. For more information, visit: https://web.dev/articles/migrate-to-ua-ch

If you don't configure this policy or set it to Default, the User-Agent header will be reduced and controlled by experimentation.

Set this policy to 'ForceEnabled' to force the reduced version of the User-Agent request header for all origins.

Set this policy to 'ForceDisabled' to always use the full (legacy) User-Agent header.
