Initial support for DNS over HTTPS (DoH) is now available in Windows 10 Insider Preview Build 19628 for Windows Insiders in the Fast ring. DoH enables DNS resolution over encrypted HTTPS connections, while DoT is designed to encrypt DNS queries via the Transport Layer Security (TLS) protocol. Microsoft boosts customers’ security and privacy on the Internet by encrypting their DNS queries and automatically removing the plain-text domain names normally present in unsecured web traffic. The feature is not enabled by default, and Insiders who want Windows to use encryption when making DNS queries will have to opt-in.
