Although you cannot uninstall IPv6 on Windows platforms, you can disable it if desired. However, Microsoft does not recommend disabling IPv6 for the following reasons:
- During the development of Windows platforms by Microsoft, services and applications were tested only with IPv6 enabled. As a result, Microsoft cannot predict what might be the consequences of disabling IPv6 on Windows.
- Some Windows features will not function if IPv6 is disabled. Examples of such features include DirectAccess and Remote Assistance.
By leaving IPv6 enabled, you can ensure that your Windows computers are fully supported and that all network-enabled features can work as intended.
