KB5077230

Microsoft has released cumulative update KB5077230 (Build 28020.1619) for Windows 11, version 26H1. Windows 11 Insider Preview build 28020.1619 – a build that belongs to the br_release development branch – is available to Windows Insider program participants on the Canary Channel.

Users on this channel will now receive updates for Windows 11, version 26H1 (Build 28020), which is activated on the basis of Windows 11, Version 26H1 (Build 28000) using the Feature Enablement package KB5073122.

• Cross-Device Resume. The Cross-Device Resume functionality, first introduced in the May 2025 optional Windows update (KB5058499), has been expanded. Users can now continue actions started on an Android smartphone directly on their PC. Supported scenarios include resuming playback in Spotify, working in Word, Excel, and PowerPoint, as well as continuing a web session. Vivo smartphone users can continue browsing pages from Vivo Browser on their PC. If you use an Android smartphone from HONOR, OPPO, Samsung, Vivo, or Xiaomi, you can continue working with online files opened in the Microsoft Copilot app on your phone. On the PC, such files will automatically open in the corresponding Microsoft 365 app (if installed). If the app is not installed, the document will open in the default browser. The feature does not support offline files stored only on the phone.
• Customizing narration in Narrator. Narrator now provides more options for customizing how interface elements are announced. The user can choose which specific details about controls will be spoken, and also adjust the order of narration according to their own navigation style across apps. These settings apply across all applications and help reduce redundant voice announcements, making working with Narrator more convenient and predictable.
• Windows Hello. Enhanced Sign-in Security (ESS) for Windows Hello now supports external fingerprint scanners. Previously, ESS was only available on PCs with built-in biometric sensors. Support now extends to devices with pluggable scanners, including desktop PCs and Copilot+ PCs. After connecting a compatible ESS fingerprint scanner, go to Settings > Accounts > Sign-in options and follow the setup instructions. This provides the most secure Windows Hello authentication option even on devices without built-in biometric modules.
• Voice input. A new setting Wait time before execution has been added to voice input settings. Users can set a delay before a voice command is executed – ranging from minimum (Instant – 0.1 seconds) to maximum (Very Long – 3.0 seconds). This provides greater flexibility for people with different speaking rates and improves recognition accuracy for both slow and fast dictation. The feature is rolling out to all types of desktop PCs, not only Copilot+ PCs.
• Voice access. An updated and simpler initial setup process for Voice Access has been introduced. The new wizard helps automatically download the appropriate speech recognition language model, select a preferred microphone, and demonstrates the basic capabilities of controlling your PC by voice. The updated setup scenario makes launching the feature faster and more understandable for new users.
• Expanded language support for the agent in Settings. Microsoft continues to expand language support for the Agent feature in Settings. Previously, in September of last year, support for French was added to the Dev and Beta channels. Now the list of supported languages has been significantly expanded. Previously supported languages: English (en-gb, en-us), French (fr-fr, fr-ca). New languages in this build: German (de-de), Portuguese (pt-br, pt-pt), Spanish (es-es, es-mx), Korean (ko-kr), Japanese (ja-jp), Hindi (hi-in), Italian (it-it), Simplified Chinese (zh-cn). This expansion of localization makes the intelligent capabilities of the agent in the Settings app more accessible to users worldwide.
• General changes. Some Windows Insider participants will see an updated SCOOBE (Second Chance Out of Box Experience) screen – an additional system setup step that allows reviewing recommended PC settings. The redesigned interface is more intuitive and simplified. Users can now select the desired recommended settings in a single window, without navigating through multiple sequential setup screens. Microsoft asks Insider participants to share feedback about the new screen through the Feedback Hub (WIN + F).
• Paint app update for Canary and Dev channels. Paint version 11.2601.391.0 adds the long-awaited Freeform Rotate feature. You can now rotate shapes, text, and selected areas at any angle. To use it, simply open Paint, select a shape, text, or selection area, and use the rotation handle that appears above the active object. This allows you to freely rotate the element in any direction. For more precise adjustment, the Custom rotate option is available in the Rotate menu, where you can manually enter a specific angle value. This new capability expands creative flexibility when editing images and simplifies fine-tuning elements on the canvas.

Installation via Windows Update. Go to Settings > Windows Update and click Check for updates. A system restart will be required to complete installation.

How the new features work:

Cross-Device Resume: Uses cloud state broker via Connected Devices Platform. Android action saves Deep Link + token in Microsoft Graph protected storage. PC polls endpoint, matches account, calls ActivateApplicationContract with restore params. Copilot files fetch URL from OneDrive/SharePoint. Offline phone files not synced due to missing shared index.

Customizing Narration in Narrator: Settings modify UIAutomationProvider and PropertyId filters in Narrator core. Registry defines priority per control type. Narrator rebuilds SYNTH queue, suppressing low-priority events. Reduces redundant announcements without breaking navigation flow.

Windows Hello Enhanced Sign-in Security (ESS): Creates secure channel between fingerprint scanner and TPM 2.0 via shared encryption key stored on sensor. USB scanners implement Microsoft Fingerprint Payload 2.0 over CCID. TPM verifies sensor signature before issuing Key Attestation, unlocking account-bound private key.

Voice Input Wait Time Before Execution: Post-processing delay in speech stack (WSR + Cloud SAPI). Recognized phrase waits configurable 0.1–3.0 sec for user refinements. Smoothing algorithm handles slow/fast dictation. Setting stored in HKCU\Software\Microsoft\Speech\WaitDelay.

Voice Access Setup Wizard: New wizard invokes Windows Update Speech Pack download via LanguageSetup.exe. Checks mic permissions, runs test phrase through local SAPI 5.4 + cloud fallback. Offers online recognition if local model fails. Auto-calibrates volume.

Expanded Language Support for Settings Agent: Agent uses local Phi-3-small RAG with ONNX embeddings per language. Language Transfer Learning maps tokens without translating rules. Enables natural language queries like "make battery last longer".

Updated SCOOBE Screen: Launches after OOBE via Task Scheduler trigger Time Since First Logon > 2 days. WinUI 3 page calls ms-settings:recommended-settings. Single window with card-based toggles. Batched atomic registry transaction.

Freeform Rotate in Paint: Direct2D transforms. Selected object gets ID2D1TransformedGeometry. Rotation handle updates quaternion matrix D2D1_MATRIX_3X2_F::Rotation. Precise angle from menu converts degrees to radians. Raster resampling deferred until commit.
