It looks like this script is designed to run from a remote computer. Do you
run it from your workstation? If so, you should be able to just kill the
wscript process with Task Manager to cancel the script. Or follow Torgeir's
advice about stopping the WMI service on the target.
Also, I'm sure that you already know this, but your script is only going to
stop Internet Explorer. If you really want to stop all internet access,
you'll need to target a number of different browsers, like Mozilla &
Firefox. Also, a clever chap could probably circumvent your script by
renaming his browser's executable.
The best way to selectively block internet access is through the use of a
firewall and/or a proxy server, of which there are many different varieties.
But that's off-topic for a scripting NG....
