After you have changed the settings to disable or enable, it’s recommended to shutdown the computer for minimum 10 seconds and restart it (Cold Restart) to take effect. Latest motherboards automatically detect these type of changes and do the cold restart. Whenever I change VT setting in my motherboard, it delays the restart automatically.
