turn Windows Firewall on or off

Make an icon to turn Windows Firewall on or off

If you use the built-in Windows Firewall, you probably have to turn it off occasionally to troubleshooting networking problems. Then you have to turn it back on. Going through the menu to do that can be a hassle. Why not create a shortcut to make it easier? Here's how:
Right click an empty spot on the desktop and select New, then Shortcut
In the shortcut wizard dialog box, under "type the location of the item," type netsh firewall set opmode disable
On the next screen, when you're asked for a name for the shortcut, type Disable Firewall
Repeat steps 1 and 3 but this time type netsh firewall set opmode enable for the location and type Enable Firewall for the shortcut name.
