KB5083769

Microsoft has released cumulative update KB5083769 for Windows 11, version 25H2 (2025 Update) as part of Patch Tuesday (April 2026). This update includes quality improvements — no new system features are introduced, however it contains all fixes and changes from the previous update KB5086672 (Build 26200.8117), and brings refinements to the Settings app with improved structure and data display, fixes and new features in File Explorer, as well as support for displays with a refresh rate of 1000 Hz and higher.

• Secure Boot. The Windows Security app (Settings > Privacy & security > Windows Security) may now display the status of Secure Boot certificate updates. The system shows notifications and status icons. On commercial devices this feature is disabled by default. As part of the Windows quality update, additional data has been added to accurately determine compatible devices, expanding the list of devices that can automatically receive new Secure Boot certificates. Certificate installation occurs in stages — only on devices where successful updates have been recorded, ensuring controlled roll-out.
• Network. Improved reliability when using SMB compression over QUIC. After installing the update, such requests perform more stably, reducing the likelihood of timeouts and improving overall connection performance.
• Remote Desktop. Enhanced protection against phishing attacks using Remote Desktop (.rdp) files. Now when opening an .rdp file, all connection parameters are displayed before the connection is established, and they are disabled by default. The first time you open such a file, a security warning also appears.

Fixed an issue where the device could enter BitLocker recovery mode after Secure Boot updates. Also resolved an error where resetting the device could fail when selecting the Keep my files or Remove everything options — this issue occurred after installing security update KB5079420 (hotpatch for March 2026). If you have installed previous updates, only the new updates contained in this package will be downloaded and installed on your device.
