Make Linux use a random MAC address, then block the physical MAC in the DHCP section of the router'e configuration. This will make Windows unablento recieve an IP address while Linux will be able to get ahold of one.
If windows uses tandom mac addresses, the feature should be able to be turned off.
Or, simply disable the network interfaces in Windows' control panel. I've never seen Windows reenable a network card by itself.
Where's the source for the supposed U-turn? I only see the article defending TPM.
