Windows 10 Insider Preview Build 19628 Releases: support for DNS over HTTPS

2 min read

Microsoft has now pushed Windows 10 Insider Preview Build 19628 for a fast ring channel to bring DNS over HTTPS (DoH) function. This is a very important security update for the Windows 10 operating system. Encrypting DNS query requests helps improve user privacy. At the same time, Microsoft also changed the code of this version and later versions to MN_RELEASE, where MN stands for manganese, which is the development code of Windows 10 v2009.Windows 10 v2004 update

Microsoft has announced in advance in the fall of 2019 that Windows 10 will support the DoH function, which is designed to encrypt all DNS queries to protect user privacy.

At present, some public DNS servers already support the encrypted query function, which can be used when the user upgrades to the latest version and configures the encrypted DNS server.

However, in the beta version, Microsoft has not enabled and configured the DoH function by default. Users must modify the registry to enable the DoH configuration DNS server according to Microsoft guidelines.
