Microsoft will support TLS 1.3 protocol in Windows 10 21H1

Windows 10 21H1 version is a new version that Microsoft will launch in the spring of 2021. Although it is a new version, this version is only a minor update without new features.

However, Microsoft has brought some system optimizations and improvements in this version, such as DNS over HTTPS encrypted query protocol and TLS version 1.3 security protocol.

At present, these security protocols have been supported in the Windows 10 beta, but Microsoft has not clearly stated when the stable channel will provide support.

According to the latest support document officially released by Microsoft, both Windows 10 21H1 and Windows Server 21H1 will support the TLS 1.3 protocol.

Mozilla Firefox no longer supports TLS

This protocol is the latest stable version of the TLS protocol. At present, the encryption security protocol adopted by most websites is TLS 1.2 version, and TLS 1.1 & TLS 1.0 will soon be abandoned.

In fact, Microsoft has started to abandon TLS 1.1 & TLS 1.0 in the IE browser. The main reason for the abandonment of the old version is that there are some security flaws and it is not safe enough.

Therefore, support for the latest version of the protocol helps to expand the use of the security protocol. After all, the old version is always replaced by the new version, but it takes some time to transition.

If nothing happens, Windows 10 21H1 will also support the DNS over HTTPS function, which is designed to encrypt DNS queries to prevent sniffing.

At present, DNS query protocols are mainly plaintext queries, so network operators can snoop on the user access information. This practice can be prevented by enabling HTTPS encryption.

However, Microsoft has not yet clearly stated whether the DoH function will be supported in the 21H1 version, and it has already supported configuring DoH during the Windows 10 Dev test phase.

So we can also look forward to this feature. After the stable version provides support, we can set Windows 10 to encrypt queries to improve privacy and security.
