Isolate a PC from the internet without any physical steps

Hello,

In Windows 7, how do you completely—but reversibly*—isolate a PC from all internet and /or network signals without:

    • turning off the computer
    • disconnecting the ethernet cord
    • disabling the modem or router
    • discontinuing payments on your ISP bill
    • utilizing any other physical methods

I got to the point shown in the following screenshot but wasn't sure where to go from there.

User generated imageI even clicked where it says "Connect or disconnect"—which I thought offered the very real possibility of disconnecting (Wouldn't you?)—but all it did is popped up a ...uh... a "pop-up" above my Taskbar tray which gave me the ability to refresh my connection and also link back to where I already was. (Boy, that would give the Excel circular-reference police a heyday!)

And by the way, I'm referring to being isolated from both wireless and wired signals.

Thanks

* i.e. disconnect then reconnect without having to change any connections or reboot


PS  Apologies for the attempted levity. It's late.  :P

On the firewall/router block the MAC addresses based packets this deals with internet, but it affecting local network traffic.
On a managed switch, disable the port to which this system is connected.

Could you provide details on what is the point of this?

But all that misses that great personal satifaction you get from cutting the ethernet cable with wire cutters and turning off the router with a hammer.  I think you're being short sited about this, Steve.

set a fake proxy.  see attached.
it can be put in a gpo for a domain and targeted to a pc/user.

let me know if that works.

A fake proxy will not prevent local Network access (though access is not defined by the asker)
The "and/or" in the OP was not clear.  Which is it?

I don't believe that a fake proxy will isolate you from the LAN.  Am I incorrect?
a fake proxy won't isolate from LAN - but is that what is meant by "network signals"?
it will isolate internet traffic.

you can create a large host file with all the other LAN entries!!!!
