SSID displayed in Wireless Networks based on previously associated MAC

I configure a fair number of wireless routers. As such, over time, my notebook may see the same physical router (access point MAC address) configured to broadcast various SSIDs. After changing the SSID on a access point, Windows is still showing the old SSID in available wireless networks. I was struggling with a router that I thought was not taking my changes only to realize it is Windows that refused to see the new SSID. I looked at Manage Wireless Networks, but there is virtually no information there. Digging into Windows Registry I find:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
and
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Signatures\Unmanaged
where I find Description (appears to be SSID), DefaultGatewayMac, DateCreated and DateLastConnected.

Searching, I was able to find the same MAC address in several different profiles.

I would expect that when Windows sees a familiar access point MAC address, and finds it no longer broadcasting the previously associated SSID, it should delete (or at least offer to delete) the old SSID.

Having discovered this problem, I think this also explains an other similar problem of Windows attempting to connect to a stored MAC address with completely incorrect settings, possibly including SSID, Security protocol, etc., and failing with a TroubleShoot Dialog. This frequently happens when I update access point security settings, but leave the SSID unchanged.

1) is there a fix for what appears to be flawed handling of Wireless networks?
2) is there a 'Manage Wireless Networks' that will let me really manage them?
To delete the duplicates Windows has created, I really need to be able to list all Profiles sorted by MAC address, then by DateLastConnected, but the 'Manager' Windows offers only shows me SSID name.

Thank you,
