Windows 7 cannot uninstall TCP/IP or open TCP/IP Properties

hi i have windows 7 home premium 64bit where im loggin as administrator. Im trying to access the properties of TCP/IP but i couldnt; when i click on TCP/IP and click on Properties; the properties screen just pops for blink seconds. Also uninstall option for TCP/IP is grayed whereas i can successfully uninstall/install other things like Client for MS Networks, File & Print Sharing for MS Networks.

I triend uninstalling network card driver and reinstalling it but still same problem.

This problem is happening with my both Wireless Network Adapter and Wired Lan adapter.
