Improvements and fixes

• [File Explorer] 

  • New! File Explorer now offers a more consistent dark mode experience. Key actions such as copy, move, and delete dialogs have been updated in both default and expanded views. Progress bars and chart views now align with the dark theme to improve readability. Confirmation dialogs for actions like skip, override, and file selection, along with multiple error dialogs, have also been refreshed for a cohesive look.

  • ​​​​​​​​​​​​​​New! The simplified File Explorer context menu for easier navigation. Common actions like Share, Copy, and Move now appear in a single organized menu. This change removes clutter and makes commands easier to find, whether you use a mouse, keyboard, or assistive technology. This change will initially be available to a small group of devices as we evaluate the best approach.

  • Fixed: File Explorer might unexpectedly not show thumbnails for video files containing certain EXIF metadata. 

  • Fixed: A toolbar might sometimes appear unexpectedly in File Explorer. 

  • Fixed: When you right-click a file, the app icon next to the Open option might appear generic instead of showing the default app for that file type. 

• [Gaming] New! The full screen experience (FSE) is now available on more Windows 11 handheld devices after its initial launch on ASUS ROG Ally and ROG Ally X. FSE gives you a console-style interface with theXbox app, making handheld gaming clean and distraction-free. It improves performance by minimizing background tasks, so gameplay stays smooth and responsive. To turn it on, go to Settings > Gaming > Full screen experience, and set Xbox as your home app. You can open FSE from Task View or Game Bar​​​​​​​, or configure your handheld to enter full screen experience on startup.

• [Input] New!  Pens that support haptic feedback—small vibrations that simulate touch—now provide tactile responses when you interact with the Windows interface. For example, you might feel vibrations when hovering over the close button or when snapping and resizing windows.

• [Keyboard] New! Keyboard backlight performance has improved on supported HID-compliant keyboards. Compatible keyboards display keys clearly in low-light environments, and the backlight adjusts to help conserve power.

  • New! You can now share an open app window with Copilot directly from the taskbar. When you hover over an open app, you’ll see the option to share its window with Copilot—similar to sharing in Microsoft Teams. Hover over the app icon, select Share with Copilot to start a conversation. Copilot Vision will analyze the content you shared and provide insights based on what’s displayed in that app.

  • Fixed: The Automatically hide the taskbar setting might unexpectedly turn off, after seeing a message saying a toolbar is already hidden on this side of your screen.  

  • Fixed: Voice access doesn't work correctly when attempting to interact with the taskbar (calling out a number might not invoke that item). 

  • Fixed: The taskbar icons might automatically scale to be smaller, although there is enough room left without scaling changes. 

• [Widgets]

  • New!  You can choose a default dashboard in Widget Board settings. When live weather is showing, the Widget Board opens the first dashboard in your navigation bar instead of the most recently used one, making the experience consistent.

• [Display and Graphics]  

  • Improved: Performance has been improved when apps query monitors for their full list of supported modes. When this happens it could previously lead to a momentary stutter on very high-resolution monitors. This work should help prevent and reduce stuttering in these scenarios. 

  • Fixed: All-in-one PCs might experience issues with their brightness slider, where it unexpectedly reverts to the original brightness when interacting with it. 

  • Fixed: Recently certain games might display the message Unsupported graphics card detected, although a supported graphics card is used.

• [Start menu] Improved: For users with the new Start menu, the Windows Search panel now matches the new Start menu in size. This update aims to create a smoother transition when searching.

• [Lock and Sign-in Screens] 

  • Fixed: It might be very slow the first time when signing into a new account. 

  • Fixed: When your lock screen is set to slide show, there might be a memory leak. Memory leaks can lead to performance or reliability issues over time.
