Windows 11 25H2
Microsoft

January 29, 2026—KB5074105 (OS Builds 26200.7705 and 26100.7705) Preview

Highlights
This update is available through two release phases: gradual rollout and normal rollout. A gradual rollout delivers an update in phases, so features reach devices over time instead of all at once, meaning availability varies by device. A normal rollout is the broad release to all eligible devices at the same time, usually when it reaches general availability (GA).

Gradual rollout
The following summary outlines features from Copilot experiences and AI-powered Windows 11 PC experiences, along with improvements and fixes. The bold text within the brackets indicates the item or area of the change.

Copilot+ PCs experiences
This section highlights updates and improvements unique to Copilot+ PCs, focusing on AI-powered features, performance enhancements, and user experience optimizations.

[Agent in Settings] New! The Settings Agent now supports more languages, with expanded support for German, Portuguese, Spanish, Korean, Japanese, Hindi, Italian, and Chinese (Simplified).

Windows 11 PC experiences
This section highlights new features and enhancements for Windows 11 PCs, including AI-powered capabilities, continuous innovation, and performance improvements.

[Cross Device Resume] New! This update expands the functionality of Cross‑Device Resume, which Microsoft first introduced in the May 2025 Windows non-security update (KB5058499). You can continue activities from your Android phone on your PC based on the apps and services you use, including resuming Spotify playback, working in Word, Excel, or PowerPoint, or continuing a browsing session.
Vivo Android phone users can continue browsing from Vivo Browser on their PC.
If you use an Android phone from HONOR, OPPO, Samsung, vivo, or Xiaomi, you can resume online files that you opened in the Microsoft Copilot app on your phone and continue working on them on your PC. Files open in the corresponding Microsoft 365 app on your PC if it is installed. If the app is not installed, the files open in your default web browser. This feature does not support offline files stored only on your phone.
[Windows MIDI Services] New! This update improves MIDI on Windows with enhanced support for MIDI 1.0 and MIDI 2.0, including full WinMM and WinRT MIDI 1.0 support with built-in translation, shared MIDI ports across apps, custom port names, loopback and app-to-app MIDI, plus performance improvements and bug fixes—delivering a better experience for musicians.
The App SDK and Tools package is a separate download that enables inbox MIDI 2.0 features and includes tools like MIDI Console and the MIDI Settings app. Releases are available on the Windows MIDI Services landing page and GitHub and are currently unsigned, which might display a security warning during download or installation.
[Narrator] New! Narrator now gives you more control over how it announces on‑screen controls. You can choose which details are spoken and adjust their order to match how you navigate apps. These settings apply throughout the app to help reduce extra speech and make Narrator easier to follow.

- [Settings] New! You can view the Device card on the Settings home page. It shows key specifications and usage details for your PC. From the card, you can go directly to Settings > System > About for more detailed information about your device. This card appears when you sign in with your Microsoft account. This feature rollout has resumed after being paused during the August 2025 release.

[Smart App Control] New! You can turn Smart App Control (SAC) on or off without any clean install requirement. To make changes, go to 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 – Microsoft Support.
[Voice Access] New! A streamlined setup makes it easier to get started with Voice Access. The redesigned experience helps you download a speech model for your chosen language, select your preferred input microphone, and learn what Voice Access can help you do on your Windows PC.
[Voice Typing] New! The Wait time before acting setting in Voice Typing enables you to adjust the delay before a voice command runs. This setting gives you flexibility for different speech patterns and improves recognition accuracy whether you speak slowly or quickly.
[Windows Hello] New! Windows Hello Enhanced Sign-in Security (ESS) now supports peripheral fingerprint sensors. This update extends this more secure sign in option beyond devices with built in fingerprint sensors to include desktops and other Windows 11 PCs, including Copilot+ PCs. To get started, plug in a supported ESS fingerprint reader, go to Settings > Accounts > Sign in options, and follow the prompts to enroll.
[Start Menu]
Fixed: This update addresses an issue where the warning message that appears when you shut down your computer while other users are signed in might be cut off at the edge of the Start menu.
Fixed: This update addresses an issue where Start menu might open on the wrong side of the screen when you use Arabic or Hebrew as your display language and the taskbar icons aren't centered.
[Kiosk mode] Changed: This update removes an error message that might show after you sign in for multi-app kiosk mode. The message said, "This operation has been cancelled due to restrictions in effect on this computer".

[Logging into your PC] Fixed: This update addresses an issue where Explorer.exe might stop responding (hang) the first time you sign in to your PC, if certain apps were configured as startup apps. This could make the taskbar not appear.
[Activation] Fixed: This update addresses an issue where, in some cases, valid Windows license migration might fail when upgrading because the device couldn’t register with the Windows Activation server for its digital license, requiring the use of the troubleshooter to fix.
[Desktop icons] Fixed: This update addresses an issue where desktop icons unexpectedly move when interacting with files, such as opening or renaming them.
[Input]: Fixed: This update addresses an issue where the keyboard character repeat delay labels in Settings > Bluetooth & Devices > Keyboard were reversed.

Normal rollout

This non-security update includes quality improvements. The following summary outlines key issues addressed by the KB update after you install it. Also, included are available new features. The bold text within the brackets indicates the item or area of the change.

[Secure Boot] This release for Windows 11, version 24H2 will execute updates in the Boot Manager on devices that already have the Windows UEFI CA 2023 certificate in their Secure Boot Signature Database (DB). It replaces the 2011 signed bootmgfw.efi with the 2023 signed bootmgfw.efi. Be advised of the consequences of resetting the DB or turning Secure Boot on or off, as this can cause a "Secure Boot violation" issue. In those rare cases, the solution is to create the Secure Boot recovery media.
[Security] New! This update adds a feature for Data Protection Application Programming Interface (DPAPI) domain backup key management. Administrators can now set how often keys rotate automatically. This strengthens cryptographic security and reduces reliance on older encryption algorithms.
[Authentication (known issue)] Fixed: This update fixes an issue where the Password icon might not appear in Sign-in options on the lock screen after you install KB5064081 or a later update.
[Display and Graphics] Fixed: This update addresses black screen issues in isolated multiuser environments, typically after a Windows upgrade.
[File Explorer] Fixed: This update addresses an issue where folder renaming with desktop.ini files in File Explorer isn't work correctly. The LocalizedResourceName setting is ignored, so custom folder names don't appear.
[Graphics] Fixed: This update addresses an issue where certain GPU configurations might recently have experienced a system error related to dxgmms2.sys, resulting in the KERNEL_SECURITY_CHECK_FAILURE error.
[Narrator] Fixed: This update addresses an issue where Narrator might not start during Windows installation from an ISO file.
[Other] Fixed: This update addresses an issue that could cause a system to stop responding during startup when Windows Boot Manager debugging is enabled. This occurs due to kdstub.dll and kdnet.dll components.
[Other] Fixed: This update addresses an issue that might cause iSCSI boot to fail with an "Inaccessible Boot Device" error.
[Other] Fixed: This update addresses an issue that affects the C Runtime (CRT) libraries in the Windows Software Development Kit. BinSkim identifies these libraries as non-compliant with the Microsoft SDL.
[Start Menu] Fixed: This update addresses an issue where, for some users, selecting the "hide this pane" button in the mobile device side panel might not lead to the setting to hide the pane.

If you installed earlier updates, your device downloads and installs only the new updates contained in this package.
