Unfortunately the Windows 10 support for 464XLAT is only where the device has a Wireless WAN (3GPP) interface. As far as I can see there's no good reason to restrict this functionality that way. If Windows 10 running desktops and laptops with wired or WiFi interfaces had it they could control the CLATs activation by checking for the presence of a working NAT64. The Network operator could control its activation by advertising DNS64 recursive DNS servers.
