Policy
Enable or disable freezing the User-Agent string at major version 99 (obsolete)
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 117. This policy was removed in Microsoft Edge 118 and is ignored if configured. This policy controls whether the User-Agent string major version should be frozen at 99. The User-Agent request header lets websites identify the application, operating system, vendor, and/or version of the requesting user agent. Some websites make assumptions about how this header is formatted and may encounter issues with version strings that include three digits in the major position (for example, 100.0.0.0). If you set this policy to 'Default' or don't configure it, then it defaults to browser settings for the User-Agent string major version. If you set this policy to 'ForceEnabled', the User-Agent string will always report the major version as 99 and include the browser's major version in the minor position. For example, browser version 101.0.0.0 would send a User-Agent request header that reports version 99.101.0.0. If you set this policy to 'ForceDisabled', the User-Agent string won't freeze the major version. This policy is temporary and will be deprecated in the future. If this policy and User-Agent Reduction are both enabled, the User-Agent version string will always be 99.0.0.0. Policy options mapping: * Default (0) = Default to browser settings for User-Agent string version. * ForceDisabled (1) = The User-Agent string won't freeze the major version. * ForceEnabled (2) = The User-Agent string will freeze the major version as 99 and include the browser's major version in the minor position. Use the preceding information when configuring this policy.
