Change WINS enrty in Registry by using s

I need to find a way to create a script to change the WINS entry in the registry on 660 PCs. Since DHCP is not an option, using scripts I need to get past the subkey for the specific NICs on each PC. Since the NICs are not all the same, the sub keyunder HKLM\System\CurrentControlSet\Services\NetBT\Adapters is different. Hence I need to find a wild card that will allow me to put in the script, a way to get past this road block to the next key to change the WINS entry. Hoofing to to all PCs is not a desired option. HELP!!!
