Microsoft has made Windows 11 build 28000.3351 (KB5127653) available as the November 2026 Security Update for devices running version 26H1. This update introduces new features and changes already available on Windows 11 25H2 and 26H2. The rollout will begin November 10, 2026, and the company usually starts deployment at 1PM Eastern Time.

According to the changelog, build 28000.3351 for Windows 11 introduces new features, usability improvements, and reliability fixes. The update includes changes to File Explorer, support for Emoji 17.0, a new Tips widget, a refreshed Magnifier toolbar, additional touchpad gestures, and an option to remap the Copilot key to Right Ctrl or the Context Menu.

The update also expands accessibility and personalization options with a setting to automatically maximize apps when they open, improved desktop background and slideshow support, and better controls for Bluetooth devices, audio, and printers. Eligible users can also enable Camera Roll Backup through OneDrive, while the Windows Recovery Environment can reuse saved Wi-Fi profiles and support remote management through mobile device management providers.

Additional improvements address power and battery reporting, Settings reliability, and Bluetooth connectivity. The normal rollout includes a fix for Remote Desktop connections affected by Administrator protection, a new Manitoba time zone ahead of its November 1, 2026, change, and improved BitLocker pre-boot PIN handling to help prevent unintended TPM lockouts. The update is being distributed in gradual and normal rollout phases, so feature availability may vary by device.

If you want to keep up with every Windows release, including Insider Preview builds and cumulative updates, the Windows Build Tracker has the full timeline.

Windows 11 26H1 is not a version for current devices. Microsoft has explicitly stated that version 26H1 is not an upgrade path for Windows 11 25H2 or earlier releases.

According to the company’s newly published Microsoft Health Dashboard page, version 26H1 is a hardware-optimized release designed to enable next-generation silicon developed in partnership with device manufacturers and silicon partners. This release will be available exclusively as a preinstalled experience on select new devices beginning in early 2026, with capabilities tailored specifically for those platforms.

Microsoft is referring to the new ARM64 PCs, starting with devices powered by the Snapdragon X2 Plus, Elite, and Extreme processors. If you own a computer running on Intel or AMD hardware, Windows 11 26H1 will never be offered to your system.

Important: Usually, Microsoft doesn’t release new features immediately. When a feature is announced as part of an update, it usually signals the start of a gradual rollout using the Controlled Feature Rollout (CFR) technology. Availability can vary based on region, hardware, and software configuration. For instance, some features take longer to reach users in Europe due to regulatory requirements.

What’s new on Windows 11 26H1 build 28000.3351

Microsoft is gradually rolling out new features and improvements with Windows 11 build 28000.3351 for version 26H1. Since these changes are part of a controlled rollout, availability may vary depending on the device configuration.

File Explorer

This update brings several usability improvements to File Explorer, starting with better handling of downloaded files. HTML files now include a “Preview anyway” button that lets you acknowledge the warning and view the file, while non-HTML files, including PDFs, are previewed automatically.

The “Home” page also remembers which sections you expanded or collapsed, so you can come back without setting everything up again. Microsoft has improved the reliability of thumbnail previews for cloud files in the “Details” pane and reorganized the pane to make file properties easier to find.

Finally, an issue that could erase the address bar contents when you click near its right side to enter edit mode has been fixed.

New Tips widget

This update introduces a Tips widget that provides short, helpful guidance on Windows features.

To try it, open the Widgets board, select “Add widgets,” and choose “Tips.” You can also add it to your lock screen in Settings > Personalization > Lock screen, so you can access helpful Windows 11 tips without opening the desktop.

Desktop personalization improvements

Windows 11 makes desktop customization more reliable, with improvements to the Personalization > Background page in Settings, higher-resolution wallpaper previews, and better preview display on portrait monitors.

The update also improves slideshow transitions on newly created accounts and the handling of rapid wallpaper changes.

You can now use DIB image files as desktop backgrounds and keep slideshow wallpapers enabled across multiple desktops without the system automatically switching the setting back to Picture.

Bluetooth gets reliability and audio fixes

Bluetooth receives a broad set of improvements to make wireless accessories more reliable. For example, during voice calls, adjusting the volume on a Bluetooth Classic Audio accessory now displays the Windows shell volume flyout, providing visual feedback.

The operating system also reports disconnected accessories more accurately, improves the stability of the “Bluetooth & devices” page in Settings, and fixes an issue where the Bluetooth radio could be off while its Settings toggle still appeared on.

The update also improves Bluetooth audio stability and compatibility, adds microphone support for certain Bluetooth Classic Audio accessories, and improves the reliability and performance of LE Audio devices and shared audio.

It also fixes a crash (error code 0x139) that could occur while streaming Bluetooth audio.

Settings improves app details and controls

The Settings app also gets several improvements. For example, the “Printers & scanners” page gains reliability improvements, while Settings > Apps > Installed apps now displays version numbers at the top level for packaged apps, matching the behavior already available for other apps.

Time pickers also better respect your preferred 12-hour or 24-hour format when configuring active hours or scheduling Night light.

Finally, the Allow multiple apps to use camera at the same time option under Settings > Bluetooth & devices > Camera now retains its setting more reliably.

Touchpads gain new scrolling gestures

Precision touchpads gain two new gesture controls under Settings > Bluetooth & devices > Touchpad. Single-finger scrolling lets you scroll vertically with one finger from either edge of the touchpad, while Automatic scrolling keeps content moving without lifting your finger as you move it near the edge.

Copilot key becomes customizable

A new Windows 11 setting lets you remap the Copilot key to act as either Right Ctrl or the Context Menu key.

This gives you more control over your keyboard and helps preserve familiar shortcuts and accessibility workflows without changing how you work.

Power and battery reporting gets a fix

Plugged-in laptops receive a fix for scenarios where the system incorrectly detects a switch from AC power to battery power.

The change improves how power status is displayed and helps prevent performance issues caused by this incorrect detection.

WinRE improves recovery and remote management

Windows Recovery Environment (WinRE) can now automatically reuse eligible Wi-Fi profiles saved in your current operating system installation, including supported certificate-based networks.

This allows devices to connect to the internet during recovery scenarios, such as Quick Machine Recovery or Cloud Rebuild, without requiring Wi-Fi credentials to be preconfigured in WinRE. The feature is enabled by default, but IT administrators can disable it.

The update also introduces a recovery remote management plug-in that extends WinRE management capabilities for mobile device management (MDM) providers, giving IT teams additional options for managing recovery environments.

Kiosk mode restricts additional keyboard shortcuts

Windows 11 disables more keyboard shortcuts in kiosk environments to help maintain their restricted experience. The “Windows key + Tab” shortcut is now disabled in restricted user experience kiosk mode, while “Windows key + A” and “Windows key + C” are disabled in single-app kiosk mode.

Accessibility adds automatic window maximization

A new “Open apps maximized” setting automatically opens app windows maximized, reducing extra steps for people using screen readers, magnification, or tablet mode, and for anyone who prefers a consistent full-screen workspace.

You can enable it under Settings > Accessibility > Visual effects. The update also improves keyboard, gamepad, or Narrator navigation of the Bluetooth Quick Settings page.

Magnifier gets a visual refresh

The Magnifier toolbar receives a cleaner look, with updated icons that better match Windows 11’s design and more consistent spacing and padding for a polished layout.

The changes are purely visual, so views, zoom controls, keyboard shortcuts, and Read Aloud continue to work as before.

Emoji 17.0 adds new designs

Windows 11 adds support for Emoji 17.0, bringing new options such as distorted face, fight cloud, and hairy creature.

Microsoft also refined existing designs, including saluting face, face with peeking eye, goose, lotus, and kissing cat, for better cross-platform consistency.

Ebrima font expands script support

The Ebrima font now supports the Garay and Beria Erfe scripts, making it the first Microsoft font to support both.

Garay was encoded in Unicode 16.0, while Beria Erfe was added in Unicode 17.0. Microsoft has also refined Ebrima’s Adlam glyph designs to align with the current Unicode standard and improve consistency.

Other fixes

This update includes a broad set of reliability improvements and small changes across Windows 11:

Remote Desktop: Fixes an issue that prevented non-admin users from connecting to remote devices with Administrator protection enabled. Connections could fail with error 0xC000000D and the message, “The token that was passed to the function is invalid.”
Date and time: Adds the (UTC-05:00) Manitoba time zone to support Manitoba’s time zone change on November 1, 2026.
BitLocker: Improves pre-boot PIN retry handling to prevent unintended repeated submissions from triggering TPM dictionary-attack lockout and requiring recovery.

Windows 11 November 2026 Patch Tuesday – Manual installation process

Since there’s always a chance of problems during and after applying a quality update, it’s recommended to prepare your computer by creating a restore point and a full backup before proceeding with the installation.

To download and install this Windows 11 update, open the “Windows Update” settings, and from the Windows Insider Program settings, enroll the device in the Release Preview channel, and click the “Check for Updates” button from the main update settings page.

If your computer has issues after installing this package, follow these instructions to uninstall the November 2026 update. If you’re unable to uninstall the update, follow these steps to recover your device.

Why the October preview becomes the November update

Microsoft develops Windows updates in stages, which can make release dates and naming confusing. Changes for a monthly update typically appear in the Release Preview channel the month before the update’s final release. Microsoft then releases the changes as an optional, non-security update in the Stable Channel, usually near the end of that month, before including them in the following month’s Patch Tuesday update.

For example, the changes previewed in October 2026 are intended for the November 2026 update. Microsoft first tests them in the Release Preview channel, then makes them available as an optional update in the Stable Channel, and finally includes them in the November 10 Patch Tuesday update. The final release can also include additional fixes and security updates.

In other words, the month a feature appears in a preview does not necessarily match the month of its final release. The October preview is an early look at changes intended for the November update.
