Supported on: Microsoft Edge version 137, Windows 7 or later

Computer Configuration\Administrative Templates\Microsoft Edge\Network settings User Configuration\Administrative Templates\Microsoft Edge\Network settings Description
Controls whether Microsoft Edge uses the Happy Eyeballs V3 algorithm to optimize connection attempts. This algorithm improves reliability and performance in dual-stack (IPv4/IPv6) networks by racing connection attempts across IP versions and HTTP protocols (e.g., HTTP/3 vs. others). For more details, see https://datatracker.ietf.org/doc/draft-pauly-happy-happyeyeballs-v3. Enabled: Uses the algorithm for connection attempts. Disabled or not configured: Disables the algorithm. Note: This policy supports dynamic refresh. Important: This policy is temporary and will be removed in a future version.

Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
