What's Changed

An Edge browser policy named WebRtcRespectOsRoutingTableEnabled is being removed. Its value in the registry changes to Delete, so that when you run the Edge category next time, it will be removed from your Edge policies.

Why

It causes problem when using Discord voice chat (WebRTC) in Edge browser while using a VPN such as Mullvad that has tight kill switch and anti-leak functionality.

You can read more about that policy here: https://learn.microsoft.com/en-us/deployedge/microsoft-edge-vpn-split-tunneling

The problem is mainly caused by 3rd party VPN software and their features. As you can see in the official article linked above, the policy is used to allow split tunneling using corporate VPNs, the ones built in Windows such as SSTP or IKEv2.

What's Next

You can use Protect-WindowsSecurity cmdlet and run the Edge browser category to apply the change if you are using a VPN + Discord in Edge browser + Voice chat and getting "no route" error.

If you aren't experiencing that issue then there is nothing you need to do.

This change doesn't decrease security whatsoever.
