Both Windows 8 and Windows Update will support IPv6

Because Windows 8 is designed to ensure connectivity across all types of networks, adding IPv6 support makes more sense.

 Supporting IPv6 is an important part of ensuring the connection and use of Windows 8. Every time a website, a multiplayer game, or a video call, these connections will be gradually transferred to IPv6. “Microsoft explained in a blog post. In addition to adding IPv6 support in Windows 8, Microsoft is also working hard to join other companies' services, such as Windows Update to support IPv6. Currently, Windows Update now supports IPv4 and IPv6, while Windows 7 and Windows Vista require IPv6 when they automatically connect to Windows Update.
