ForceMajorVersionToMinorPositionInUserAgent

Freeze User-Agent string major version at 99 - ForceMajorVersionToMinorPositionInUserAgent​

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 (e.g. 100.0.0.0).

Setting the policy to 'Default' or leaving it unset will default to browser settings for the User-Agent string major version. If set to 'ForceDisabled', the User-Agent string will not freeze the major version. If set 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.

This policy is temporary and will be deprecated in the future. Note that if this policy and User-Agent Reduction are both enabled, the User-Agent version string will always be 99.0.0.0.

  • 0 = Default to browser settings for User-Agent string version.
  • 1 = The User-Agent string will not freeze the major version.
  • 2 = The User-Agent string will freeze the major version as 99 and include the browser's major version in the minor position.
