| TLS server authentication certificates using RSA keys with key lengths shorter than 2048 bits <!--8644149-->| Support for certificates using RSA keys with key lengths shorter than 2048 bits will be deprecated. Internet standards and regulatory bodies disallowed the use of 1024-bit keys in 2013, recommending specifically that RSA keys should have a key length of 2048 bits or longer. For more information, see [Transitioning of Cryptographic Algorithms and Key Sizes - Discussion Paper (nist.gov)](https://csrc.nist.gov/CSRC/media/Projects/Key-Management/documents/transitions/Transitioning_CryptoAlgos_070209.pdf). This deprecation focuses on ensuring that all RSA certificates used for TLS server authentication must have key lengths greater than or equal to 2048 bits to be considered valid by Windows. </br></br> TLS certificates issued by enterprise or test certification authorities (CA) aren't impacted with this change. However, we recommend that they be updated to RSA keys greater than or equal to 2048 bits as a security best practice. This change is necessary to preserve security of Windows customers using certificates for authentication and cryptographic purposes.| March 2024|

| Windows Mixed Reality <!--8412877--> | [Windows Mixed Reality](/windows/mixed-reality/enthusiast-guide/before-you-start) is deprecated and will be removed in Windows 11, version 24H2. This deprecation includes the [Mixed Reality Portal](/windows/mixed-reality/enthusiast-guide/install-windows-mixed-reality) app, [Windows Mixed Reality for SteamVR](/windows/mixed-reality/enthusiast-guide/using-steamvr-with-windows-mixed-reality), and Steam VR Beta. Existing Windows Mixed Reality devices will continue to work with Steam through November 2026, if users remain on their current released version of Windows 11, version 23H2. After November 2026, Windows Mixed Reality will no longer receive security updates, nonsecurity updates, bug fixes, technical support, or online technical content updates.</br> </br>This deprecation doesn't affect HoloLens. We remain committed to HoloLens and our enterprise customers. | December 2023 |
