2.Changing MAC address to 9a:56:ac:fc:24:88
reg add HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0001 /v NetworkAddress /d 9a56acfc2488  /f

3.Verify the new mac address, and restart the network, nic can not get ip adress
netsh interface set interface name="Ethernet Instance 0" admin=DISABLED
netsh interface set interface name="Ethernet Instance 0" admin=ENABLED


C:\Windows\system32> ipconfig /all
