wireless networking - How do I delete previous network connections from Windows 7?

Windows 7 shows 3 network connections under the "change adapter settings"... a local area connection and 2 wireless network connections (one hardware and one MS virtual WiFi miniport). I'm fine with this, but ever since I removed the old WiFi NIC and installed a new one, the wireless network connections have been renamed to wireless network connection 5 (hardware) and wireless network connection 6 (virtual). It's up to 5 and 6 because I had to reinstall the new WiFi NIC a few times to try out different driver versions. I uninstalled the drivers each and every time though.

Anyways, it used to be wireless network connection and wireless network connection 2. When I tried to rename them, Windows tells me that the name already exists; however, 1 thru 4 do not show up in the network connections. How do I delete the old connections if I don't even see them?

Also, I noticed something else about the wireless network connections. I noticed that the wireless network connection 5 used, for example, the name of my NIC (Atheros blah blah #2). The wireless network connection 6 used the MS virtual WiFi miniport #4. Where did the 2 and 4 come from? In the registry I noticed under HKLM\system\controlset001\control\network{4D36E972-E325-11CE-BFC1-08002BE10318}\descriptions that the value data for the Atheros had 1 2, while the MS virtual's value data had 1 2 3 4. For comparison, my Realtek only had 1 for its value data. I wonder if I modified the value data and changed it to 1 on the Atheros and MS virtual that it'll change the name of the adapter (note that this is separate from the question above which is renaming the connection).
