they should work for win 7 if they work at all.. as far as i know for most tapping programs the only requirement is that your internet connection to disconnect/reconnect has to be named "Local Area Connection"
you can try to google for such a program if you're impatient and dont want to wait for somebody on win 7 to create one.. although you would need to most likely use different terminology for tapper, like "Windows 7 Internet Disconnector" or something to that effect
