Biggest Windows 11 26H1 June Update – Huge Performance Boost, New Settings (Build 28000.2340 or KB5095091)

In this article, we will talk about the Biggest Windows 11 26H1 May 2026 Update, Build 28000.2340 or KB5095091.

Microsoft has Released Windows 11 26H1, which is a New Version that Microsoft is using to test the New Platform for the upcoming Qualcomm Snapdragon X2 Devices and Nvidia N1X Processors.

Windows 11, version 26H1 will only be available on new devices that will be released to the market in early 2026 and it is not offered as an in-place update from Windows 11, version 24H2 or 25H2 on existing devices.

Devices running Windows 11, version 26H1 will continue receiving monthly updates for security, quality, and new features, the same as devices running Windows 11, versions 24H2 and 25H2.

Devices running Windows 11, version 26H1 will not be able to update to the next annual feature update in the second half of 2026. This is because Windows 11, version 26H1 is based on a different Windows core than Windows 11, versions 24H2 and 25H2, and the upcoming feature update. These devices will have a path to update in a future Windows release.

New Features in this Build

It helps reduce downtime and simplifies troubleshooting when issues occur. To learn more, see Point-in-time restore for Windows.
• [Magnifier in Windows]
  •  Magnifier now provides clearer and more consistent announcements when working with a screen reader. You’ll hear helpful announcements when you zoom in or out, switch views, turn color inversion on or off, or turn Magnifier on or off. This makes it easy to stay oriented while you work.
  •  Magnifier now supports magnification of permitted protected content.
  • This update improves smoothness when moving Magnifier in lens mode.
• [Task Manager]
  •  Task Manager now offers improved visibility into NPU usage on PCs with an NPU.

Neural engines that are part of a GPU now appear on the Performance page, providing a more complete view of AI-related activity. A new optional Isolation column on the Processes and Details pages shows which apps are running in an AppContainer. You can add any of the new columns by right-clicking a column header in Task Manager and selecting them from the menu.
  • This update improves CPU speed display on the Performance page of Task Manager for VMs, so it doesn’t show higher than unexpected numbers after resuming from hibernate.
• [Camera]  Windows 11’s Multi-App Camera feature allows multiple applications to access your camera stream at the same time. Basic Camera mode in Windows 11 enables simplified camera functionality, useful for troubleshooting or improving stability when your camera is not working correctly. Enterprise admin can now set Multi-App Camera mode or Basic Camera mode through Group Policy, under Computer Configuration > Administrative Templates > Windows Components > Camera > Configure Camera Options.
• [Windows Setup] You can now choose a custom name for your user folder on the Device Name page during Windows setup. The updated experience makes it easier to select a custom name during setup only. If this step is skipped, Windows uses the default folder name and continues setup as usual. User folder names must follow standard Windows naming requirements.
• [General Performance] This update accelerates app launch and core shell experiences such as Start menu, Search, and Action Center.
• [Personalization] This update improves:
  • Color selection accuracy when adjusting your accent color to match your wallpaper when the automatic accent color selection is enabled in Personalization settings.

When Windows Hello face or fingerprint is set up and available, it is now the default sign-in method every time you sign in, even if you used a different method previously. If you need to use your Windows PIN instead and use it three times in a row, Windows will stay with PIN until you switch to another sign-in method.
• [Windows Search Box] Windows Search will now find and prioritize files with as few as two characters.
• [Storage]
  • The dialog box for creating a Dev Drive now supports specifying the size in gigabytes (GB) instead of only megabytes (MB). This option is also available when resizing volumes in Settings > System > Storage.
  • In Settings > System > Storage, you now see a User Account Control (UAC) prompt only when you choose to view temporary files, instead of immediately when opening the page.
• [USB]
  • This update improves reliability for displays attached to USB4 docks and hubs. These displays now light up more consistently, particularly when coming out of standby.
  • The USB3 stack is updated to have additional resiliency and recovery measures in place against certain unexpected hardware faults and conditions. Users will experience higher reliability with USB devices.
• [Sensors] This update improves resiliency against apps that could keep the sensor hub powered on and drain power, impacting battery life.
• [Human Interface Device (HID)] This update improves battery life related to the HID and Input stack for failed HID devices. Power hygiene is also improved against applications that might initiate HID transfers during standby.
• [Input] The update improves:

  • Reliability of explorer.exe when closing the input switcher.
  • Performance when opening or navigating to clipboard history.
• [Fonts] The Times New Roman font family is updated to improve the rendering of combining diacritical marks across Greek and Cyrillic scripts.

• [Emoji Panel Update] The emoji panel (Windows key + period (.)) now uses GIPHY for GIF content following the deprecation of Google’s Tenor API. Starting June 30, 2026, install the latest Windows update to continue using GIFs in the Emoji panel. If you don’t update, you will see a “GIF service is not available” error in the panel.
