:: Change MAC script by bobdynlan, release 1
:: For each network adapter it will list RegPath, GUID, Name, previous modified MAC if exists

:: You can paste directly from ipconfig or wireshark because : < > { } [ ] - ( ) . will be filtered out
:: Note that for wireless in Win7 standard drivers has to start with 02... 06... 0A... 0E...
