A gradual rollout distributes a release update over a period of time, rather than all at once. This means that users receive the updates at different times, and it might not be immediately available to all users. To see the status of this feature, go to Windows release health dashboard.​​​​​​​​​​​​ 

  • [App defaults]

    • New! We are rolling out some small changes in the European Economic Area (EEA) region for default browsers through the Set default button in Settings > Apps > Default apps:

      • Additional file and link types will be set for the new default browser, if it registers them.

      • The new default browser will be pinned to the Taskbar and Start menu unless you choose not to pin it by clearing the checkboxes.

      • There is now a separate one-click button for browsers to change your .pdf default, if the browser registers for the .pdf file type.

  • [Click to Do (Preview)]New!​​​​​​​ Ask Microsoft 365 Copilot is a new action in Click to Do on Copilot+ PCs. Use it to send text or images to Microsoft 365 Copilot, which will respond to your questions. The Ask Microsoft 365 Copilot action requires a Microsoft 365 license and follows your organization’s privacy policies.

  • [Narrator]

    • New! The Screen Curtain feature in Narrator helps protect your privacy and improve focus by blacking out the screen while Narrator reads content aloud. This is especially helpful in public or shared spaces, where you can work with sensitive information without others seeing your screen. To turn on Narrator, press Ctrl + Windows + Enter. Then press Caps Lock + Ctrl + C to turn on Screen Curtain. While it’s on, you can use Narrator as usual with the screen hidden. Press Caps Lock + Ctrl + C again to turn it off.

    • New! Narrator makes it easier to discover and learn about its features directly within the experience. Whether you're new or exploring advanced options, Narrator will guide you through the latest updates using a series of steps and prompts that explain each new feature and change.

  • [PC Migration]New!​​​​​​​ The PC-to-PC migration experience in Windows is starting to roll out. You’ll begin to see the landing and the pairing page in the Windows Backup app, giving you a first look at what’s coming. In the full experience, you’ll be able to transfer files and settings from an old PC to a new one during setup. Support for this feature during PC setup will arrive in a future update. The rollout is being introduced in phases to support a smooth experience.

  • [Settings]

    • ​​​​​​​New!​​​​​​​ We are starting to roll out the Settings homepage for commercial customers on PCs managed by an IT administrator. The feature will show some existing cards relevant to enterprise-managed PCs like “Recommended settings” and “Bluetooth devices” as well as two new enterprise-specific device info and accessibility preferences cards. For commercial customers who also use their Microsoft account on their managed PC, there will also be a new accounts card indicating the presence of both work and school and Microsoft account types. ​​​​​​​

    • New! The country or region selected during device setup now appears under Settings > Time & language > Language & region.

    • Fixed: The storage card in Settings > System > About shows an incorrect or unreadable character instead of the proper disk size.

  • [Taskbar & System Tray] 

    • New!​​​​​​​ ​​​​​​​​​​​​​​The taskbar now resizes icons to fit more apps when space runs low, keeping everything visible and easy to access. You can adjust how icons appear in settings—reduce icon size only when the taskbar is full (default), keep icons at their original size at all times by selecting Never, or use smaller icons all the time by selecting Always. To change this setting, right-click an empty area on the taskbar, select Taskbar settings, expand the Taskbar behaviors section, and choose your preference under Show smaller taskbar buttons.

    • New! In addition to the new grouping of the Accessibility menu in Quick settings, there are text descriptions for the assistive technologies like Narrator, Voice access, and more for easier identification and learning.

    • New! Adjusted the indicator (pill) under taskbar apps to make it wider and more visible.​​​​​​​

    • Fixed: WIN + CTRL + Number doesn't work anymore for switching windows of an open app in the taskbar.​​​​​​​

    • Fixed: When using taskbar in Windows, the media controls that appear in the preview windows for apps might unexpectedly flicker.

  • [Voice Access]

    • New! You can now use Voice access to navigate, dictate, and interact with Windows using voice commands in Simplified Chinese, Traditional Chinese, and Japanese.

    • New! You can add custom words to the dictionary in voice access. The feature will be available in all the currently supported voice access languages.

  • [Windows Share]

    • ​​​​​​​New! When you share links or web content using the Windows share window, you'll see a visual preview for that content.

    • New! In the Windows share window, you can select a compression level—High, Medium, or Low Quality—when editing and sharing images, instead of selecting from a 0–100 scale.

  • [Color] Improved: Adjusted the location of the intensity and color boost sliders under Settings > Accessibility > Color Filters, so the color previews at the top of the page remain visible while adjusting the sliders. 

  • [File Explorer] Improved: Performance has been enhanced when extracting archive files - this will particularly help in the case of copy pasting large numbers of files out of large 7z or .rar archives.

  • [Graphics]

    • Improved: Made underlying changes to enhance display related user experiences, including reducing screen flashing during certain display configuration transitions and eliminating unnecessary display resets that occurred in some cases​​​​​​​.

    • Fixed: Some displays might be unexpectedly green.

    • Fixed: If User Account Control (UAC) is set to Always Notify and the button under Settings > System > Display color calibration is selected for your display and canceled, Settings will stop responding.

  • [Input] Fixed: Typing in Japanese with the touch keyboard might stop working after switching to typing with an English keyboard and then switching back.

  • [MSFTEdit.dll] Fixed: Some apps like Sticky Notes and dxdiag might stop responding when the display language is set to Arabic or Hebrew display.

  • [Quick Settings] Fixed: The top three buttons in the top row don’t respond when selecting to enable or disable them.

  • [Printing] Fixed: Printed lines might be unexpectedly thicker than expected.

  • [Scripting] Fixed: Running a script on a remote Server Message Block (SMB) share might take an unexpectedly long time if the share is hosted on an older Windows Server version like Windows Server 2019.

  • [Windowing] 

    • ​​​​​​​Fixed: When you press ALT + Tab to switch out of a full screen game, other windows like Windows Terminal might stop responding.

    • Fixed: An underlying issue might lead to unexpected changes to window size and position after sleep and resume on some devices.

    • Fixed: Explorer.exe might stop working unexpectedly when a window is dragged, if window snapping is enabled.

Noto fonts issue

Applies to: All users

Symptom

There are reports of blurry or unclear CJK (Chinese, Japanese, Korean) text when displayed at 96 DPI (100% scaling) in Chromium-based browsers such as Microsoft Edge and Google Chrome. The March 2025 Preview Update introduced Noto fonts in collaboration with Google, for CJK languages as fallbacks to improve text rendering when websites or apps don’t specify appropriate fonts. The issue is due to limited pixel density at 96 DPI, which can reduce the clarity and alignment of CJK characters. Increasing the display scaling improves clarity by enhancing text rendering.

Workaround

As a temporary workaround, increase your display scaling to 125% or 150% to improve text clarity. For more information, see Change your screen resolution and layout in Windows.

We are investigating this issue and will provide more information when it is available.
