Microsoft Notifies Users About Discontinuation of Support for Outdated TLS Protocols
Microsoft has recently notified users about their decision to discontinue support for protocols TLS 1.0 and TLS 1.1 in future Windows updates. The company had previously published instructions regarding these upcoming changes.
While existing versions of Windows 11 22H2, 21H2, and Windows 10 will continue to support outdated TLS protocols until the 23H2 update and Windows 12 release next year, test versions of Windows 11 Insider Preview starting from September 2023 will disconnect these protocol versions by default. However, users will still have the option to manually enable them to ensure compatibility.
TLS, which stands for Transport Layer Security, is a cryptographic protocol used for secure data transfer over the Internet. The original TLS 1.0 and its successor TLS 1.1 had been in use for over 20 years since their introductions in 1999 and 2006, respectively. Due to security concerns, the Internet Engineering Task Force (IETF) officially declared these versions outdated in March 2021. Subsequently, the IETF approved TLS 1.3 as the next major version of the protocol in March 2018.
In 2021, Apple made the decision to discontinue support for TLS 1.0 and 1.1 in its operating systems, including iOS 15, iPadOS 15, macOS 12, watchOS 8, and tvOS 15, as well as all future versions. The company strongly advised application developers who still employed the outdated protocol versions to immediately transition to TLS 1.3, highlighting its superior speed and security compared to TLS 1.2.
