How to disable TCP/IPv6 (IPv6) on Windows 11

On Windows 11, by default, the system uses the Internet Protocol version 6 (TCP/IPv6) and IPv4 protocols in a dual-stack configuration. Although IPv4 is still the primary protocol in local networks, using both versions is a good idea since more and more modern applications depend on the protocol. 

However, if IPv6 is causing problems in a specific scenario or you determine there’s no need for the networking feature in your network, Windows 11 provides various ways to disable it. For example, disabling IPv6 has been known to fix issues with PC Game Pass games not syncing or installing correctly, in some situations. Microsoft offers a variety of ways to turn off Internet Protocol version 6 through the Settings app, Command Prompt, and PowerShell.
