You run the following command to disable the TCP/IP Version 4 (TCP/IPv4) protocol on all network connections on a Windows Vista-based computer:

netsh interface IPV4 uninstall

You restart the computer, and then you view the properties of a network connection in Control Panel.

However, the Internet Protocol Version 4 (TCP/IPv4) check box is still selected. Therefore, the properties of the network connection incorrectly show that the TCP/IPv4 protocol is enabled. This behavior occurs even though you disabled the protocol from all network connections on the computer.
