Use Windows proxy resolver

This policy will be superseded by a similar feature in a future release. For more information, see https://crbug.com/1032820.

Use Windows to resolve proxies for all browser networking instead of the proxy resolver built into Microsoft Edge. The Windows proxy resolver enables Windows proxy features such as DirectAccess/NRPT.

This policy comes with the problems described by https://crbug.com/644030. It causes PAC files to be fetched and executed by Windows code, including PAC files set via the 'ProxyPacUrl' (Set the proxy .pac file URL) policy. Since network fetches for the PAC file happen via Windows instead of Microsoft Edge code, network policies such as 'DnsOverHttpsMode' (Control the mode of DNS-over-HTTPS) won't apply to network fetches for a PAC file.

If you enable this policy, the Windows proxy resolver is used.

If you disable or don't configure this policy, the Microsoft Edge proxy resolver is used.
