Microsoft has released Windows 11 KB5083769 and KB5082052 cumulative updates for versions 25H2/24H2 and 23H2 to fix security vulnerabilities, bugs, and add new features. Today's updates are mandatory as they contain the April 2026 Patch Tuesday security patches for vulnerabilities discovered in previous months. You can install today's update by going to Start > Settings > Windows Update and clicking on 'Check for Updates.' You can also manually download and install the update from the Microsoft Update Catalog. This is the fourth 'Patch Tuesday' release in 2026, and it's based on 24H2, which means 25H2 gets the same update. There are no exclusive or special changes. You'll get the same fixes across the two versions of Windows 11. After installing today's security updates, Windows 11 25H2 (KB5083769) will have its build number changed to 26200.8246 25H2 and 26100.8246 (24H2), and 23H2 (KB5082052) will be changed to 22631.6936. After the update, Smart App Control can now be modified without installing a fresh copy of Windows 11. In addition, Microsoft has patched issues with sfc /scannow where it fails to correctly report the error message. [Narrator] New! 1 Narrator provides rich image descriptions on Copilot+ PCs and now works with Copilot on all Windows 11 devices. Press Narrator key + Ctrl + D to describe the focused image or Narrator key + Ctrl + S to describe the full screen. Copilot opens with the image ready, allowing you to enter a prompt for a customized description. The image is shared only after you choose to describe it. On Copilot+ PCs, Narrator gives instant, on‑device descriptions, and you can select Ask Copilot for more detail. [Smart App Control] New! You can turn Smart App Control (SAC) on or off without needing a clean install. To make changes, go to Settings > Windows Security > App & Browser Control > Smart App Control settings. When turned on, SAC helps block untrusted or potentially harmful apps. To learn more, see App & Browser Control in the Windows Security App. This feature was previously disclosed in January 2026 (KB5074105) and is now beginning to roll out.
