Insider KB5127844 Windows 11 Insider Experimental (26H1) build 28120.3272 - Oct. 16



 Microsoft Support:

Changes and improvements gradually being rolled out*​

  • This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.

[Search]​

  • Search home has been simplified to reduce visual clutter and make it easier to get back to recent searches quickly.
  • Search does a better job showing where a result comes from, whether it's an app, setting, file, web result, or Store suggestion, so it's easier to tell what you're looking at and where you'll go before you click.
  • A new setting in Settings > Privacy & security > Search lets you choose whether web and Microsoft Store suggestions appear alongside local results.

[Pointer Indicator]​

  • We're introducing the Pointer Indicator accessibility setting. This feature enables Windows users with low vision to easily locate and use their cursor to increase productivity and efficiency when using a Windows device.
  • To enable this experience, go to Settings > Accessibility > Mouse pointer and touch, and enable the Pointer indicator setting. You can also search for the setting by name. When the setting is enabled, you can toggle it on or off with the keyboard shortcut, Windows logo key + Ctrl + Shift + X.

[Live Captions]​

  • We're improving Live Captions with a new Include Screen Reader audio setting, which is off by default. With the setting off, Live Captions won't transcribe audio from screen readers such as Narrator, JAWS, and NVDA, keeping captions focused on microphone and system audio.

[Settings - Privacy & security]​

  • The improved Privacy & security page in Windows Settings helps you find the Camera, Microphone, and Location privacy controls more easily. It groups similar controls across the page and brings usage information from deeper linked pages onto this page.

[Family Safety]​

  • Improved family safety messaging when applications are blocked because of age-restricted parental controls.

[Other]​

  • Fixed an issue with msmpeg2ac3dec.dll which was leading to some apps and games crashing recently.

Reminder for Windows Insiders in the Experimental (26H1) channel​

  • These builds can be unstable and might be released with limited documentation.
  • Many features in the Experimental (26H1) channel 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.
  • The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
  • Some features in active development we preview with Windows Insiders might not be fully localized, and localization will happen over time as features are finalized. As you see issues with localization in your language, report those issues to us via Feedback Hub.
  • Check out Flight Hub for a complete look at what build is in which Insider channel.
