I would like to block Internet access for my own machine. This is so that no apps can talk to the outside in the time frame I want it to. I know a firewall can do this but I don't want to install one. I don't want to use the included one. I know also I can change the gateway but that involves several clicks. I am looking for a system tray software or simple desktop app to toggle the access. On/Off with a single click.

Do you still need local network connectivity, or would it work to disable your network access completely? – nhinkle Dec 15 '10 at 8:57
I don't need local connectivity. – Tony_Henrich Dec 15 '10 at 17:36

You don't specify whether you need local connectivity as well. If you don't, the so-simple-someone-could-easily-overlook-it, 100% foolproof solution is to just unplug the network cable.

If it's a laptop or netbook, those tend to have a button to turn off disable wifi connection – Corey Dec 15 '10 at 16:40
I am not using wifi. Unplugging works but I don't want to do that. I should have added this to the options I don't want to use. – Tony_Henrich Dec 15 '10 at 17:37
@Tony - So basically, you don't want to do anything easy? Have it your way, I guess. Maybe you'll luck out and somebody will find an app that does nothing but enable and disable the network adapter for you with a single click, but I've never seen such a thing. – Shinrai Dec 15 '10 at 20:12

In Windows 7 it's just

ipconfig /release


ipconfig /renew

Create two batch files, one to release your IP address and one to renew your IP address. Then create a shortcut to each of them in your Quick Launch toolbar.

To disconnect:

ipconfig /release

To connect:

ipconfig /renew
