Windows 12 and Next-Generation Windows 11 to Disable TLS 1.0 and 1.1
Microsoft has issued a notification titled “TLS 1.0 and TLS 1.1 to be Disabled in Future Windows Operating Systems,” reminding users that the upcoming versions of Windows will phase out TLS (Transport Layer Security) protocols 1.0 and 1.1.
This marks the second important reminder from the company this week, previously stating that users of Windows 11 21H2 would soon be forced to upgrade.
If you’re not already aware of this impending change, Microsoft provided guidance on it nearly a month ago. Microsoft noted that the currently available Windows versions, including Windows 11 22H2, 21H2, and Windows 10, still utilize TLS 1.0 and TLS 1.1. This means that upcoming feature updates, such as 23H2, and Windows 12, slated for release next year, will disable these features, starting with the Insider version set to launch later this month. This is part of broader efforts to enhance the security of the next-generation Windows.
However, the company added that, for the sake of compatibility, options will be provided to re-enable these features. It stated:
Transport Layer Security (TLS) is the most commonly used internet protocol for establishing encrypted communication channels between clients and servers. Over the past few years, due to various security concerns, internet standards and regulatory bodies have deprecated or prohibited the use of TLS 1.0 and 1.1. As a result, future Windows operating systems will default to disabling TLS 1.0 and 1.1. This change applies only to future new Windows operating systems, both client and server versions. Existing released versions of Windows will not be affected by this change. The Windows 11 Insider Preview versions, starting from September 2023, will default to disabling TLS 1.0 and 1.1. Users who need to maintain compatibility can choose to re-enable TLS 1.0 or TLS 1.1.
Home users of Windows are unlikely to encounter any issues related to this change. Enterprises will need to test their environments to detect and update or replace any affected applications.
