Insider KB5082255 Windows 11 Insider Beta build 26220.7935 (25H2) - March 4

UPDATE 3/6:



[UPDATE 3/4/26]: We are rolling out standalone Update Build 26220.7935 (KB5082255). This update does not include anything new and is designed to test our servicing pipeline for builds in the Beta Channel. A restart will be required.

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26220.7934 (KB5077242) to the Beta Channel.

Changes in Beta Channel builds and updates are documented in two buckets: new features, and improvements (including notable fixes) that are being gradually rolled out for Insiders who have turned on the toggle to get the latest updates as they are available (via Settings > Windows Update*) and then new features, and improvements (including notable fixes) rolling out to everyone in the Beta Channel. For more information, see the Reminders section at the bottom of this blog post.

New features gradually being rolled out with toggle on*​

[Enhanced security and performance for batch files]​

We are giving administrators and Application Control for Business policy authors additional controls over the processing of batch files and CMD scripts. Starting with this release, administrators may enable a more secure mode for processing batch files that ensures they do not change during execution by adding a value to the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor named LockBatchFilesInUse (DWORD, value 0 or 1). Policy authors may also use the LockBatchFilesWhenInUse application manifest control documented here to enable this mode.

This enhances the performance and security of batch file processing when code integrity is enabled, as signature validation will only required to be performed a single time, instead of per statement executed in the batch file.

Changes and Improvements gradually being rolled out with toggle on*​

[Shared audio (preview) gets more control]​

• Shared audio (preview) was first announced last fall, and allows 2 people to share audio between their two capable Bluetooth LE Audio headphones, speakers, earbuds, or hearing aids. With this update Windows now provides individual sliders for each listener which adjusts their volume without affecting the other. You can continue to adjust volume for both listeners at the same time through the main volume controls available through Quick Settings or on-device and keyboard controls.
• You’ll also see a new taskbar indicator while you’re sharing, giving a quick reminder that audio is still being shared. Clicking the indicator is a fast path to open sharing settings to change volume or stop sharing.
• The LE Audio accessory ecosystem also continues to grow. In addition to the accessories announced before, we’re excited to share that the Samsung Galaxy Buds 4 and Buds 4 Pro, Sony WF‑1000XM6, and Xbox Wireless Headset all have support for shared audio!

Paint App update rolling out​

• With Paint version 11.2601.391.0, we’re excited to introduce freeform rotate, a highly requested feature that gives you more control when editing your artwork. You can now rotate shapes, text, and any active selection to any angle. To get started, open Paint and select a shape, text, or selection. When the object is active, use the rotate handle above it to rotate freely in any direction. For more precise control, you can also choose Custom rotate from the Rotate menu and enter a specific angle. Try using freeform rotate in your artwork to adjust elements exactly the way you want and add more flexibility to your creative workflow.

Reminders for Windows Insiders in the Beta Channel​

• Updates are based on Windows 11, version 25H2 via an enablement package (Build 26220.7934).
• Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.
• [New] The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
• For Windows Insiders who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.
• Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.
• Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.
• Check out Flight Hub for a complete look at what build is in which Insider channel.

Thanks,
