Insider KB5083726 Windows 11 Insider Dev build 26300.8276 (25H2) - April 17


UPDATE 4/24:


 Windows Insider Blog:

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26300.8276 (KB 5083726) to the Dev Channel.

Changes in Dev 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 Dev Channel. For more information, see the Reminders section at the bottom of this blog.


Changes and Improvements gradually being rolled out with toggle on*

[Settings]

  • Based on feedback, we’re providing clarity regarding location options in Settings > Privacy & Security > Location. When Location services is turned off, options like Default location and Allow location override are unavailable because apps and services aren’t receiving location info. To make that clearer, these options will now appear disabled (greyed out) until Location services is turned back on.

  • We have improved the reliability of navigating to Settings > Apps > Installed apps.

[File Explorer]

  • We have updated iconography placement in the File Explorer search box to be more consistent across different PCs.

    Old search box.

  • Improved File Explorer reliability.
  • Improved navigation pane usage for Voice Access users.

[Windows Hello]

  • Improved reliability and performance of Windows Hello fingerprint after your PC wakes from sleep.

[Input]

  • Improved performance of opening clipboard history.

[Fonts]

  • We’ve made some font improvements, including updating the Leelawadee UI font family for the Thai, Lao, Khmer, and Lontara scripts to help improve glyph sequencing, positioning, and rendering for these scripts.

Reminders for Windows Insiders in the Dev Channel

  • Updates are based on Windows 11, version 25H2 via an enablement package (Build 26300.8276).
  • 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.
  • 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,
Windows Insider Program Team
