Looks like I missed out on this update. OpenDNS released DNSCrypt for Windows earlier this month.
They already had solutions for both OS X and Linux. Finally, we have an app for Windows OS.
The company said in a statement:
Today we proudly reveal DNSCrypt for Windows. While we’re mostly a Mac and unix shop here at OpenDNS, we care about protecting all users. Since Windows has more than 80% market share around the world we knew we could not ignore the need for DNSCrypt on Windows.
