From the developer: "Wwhois is a full functional command whois program running on windows machines. Unlike other windows whois program (they normally only shows Domain Name, Registrar, Whois Server ..), Wwhois exactly shows all of the domain information as Linux whois4.5.X does (including Domain Name, Registrar, Whois Server, Administrative Contact, Record expires date and Record created date, etc). Instead of check your desired domain name from web-based search engine like (networksolutions.com, register.com..) or need a linux machine, Wwhois is a convinient command program for windows users."
