Use the Happy Eyeballs V3 algorithm
Supported on Microsoft Windows 7 or later
What it does
This feature enables the Happy Eyeballs V3 algorithm to make connection attempts. See https://datatracker.ietf.org/doc/draft-pauly-happy-happyeyeballs-v3 for details. Setting the policy to Enabled means Google Chrome will use the Happy Eyeballs V3 algorithm for connection attempts. Setting the policy to Disabled turns off the Happy Eyeballs V3 algorithm. Not setting the policy, Google Chrome will turn on or off the Happy Eyeballs V3 algorithm based on chrome://flags/#happy-eyeballs-v3. This policy supports dynamic refresh. This policy is a temporary measure and will be removed in future versions of Google Chrome.

- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
