Get network adapter CLSID if I know name?

[jp10558]

If I know the network adapter is named, say, "Local Area Connection", can I get the CLSID from that somehow? Or is there a better way to set a static IP than running netsh? My problem is on Win7 x64, if I use netsh to set a static IP address, when I reboot, it is losing the default gateway. Per Experts Exchange, this is caused by the registry entry for Default Gateway and Default Gateway Metric having a blank line before the actual gateway IP. If you use Regedit to remove those blank lines and re-boot - your connection then will work fine... More info on the problem here:

What I'd like to do though is either script removing the blank line or set the static IP address info in a way that doesn't create the problem in Win7 x64...

Any ideas?
