Windows 11 Insider Experimental Preview Build 26300.8687

Release date: 12 June 2026

Changes and improvements gradually being rolled out

As announced in the Windows Update announce blog, we are now bringing a new unified update experience to reduce the number of reboots you see per month. We are starting by coordinating driver, .NET, and firmware updates to align with the monthly quality update, reducing the update experience to a single monthly restart. See the blog for more information.

Middle click to open a folder in a new tab is now supported in the Address Bar and the Home page for a more consistent and efficient tabbed navigation experience across File Explorer.
Improved screen reader announcements for conflict resolution dialog ("Which files do you want to keep?") when moving / copying files.
Made some more improvements to how File Explorer responds to increased text scaling.

Finding apps is more forgiving. Search is better at handling typos, dropped letters, extra letters, and partial words for apps. Queries like “utlook” can still find Outlook.
Settings results are improving. We’ve made ranking improvements to help more relevant settings appear higher in results.

Improved reliability of loading the system tray area of the taskbar.
Fixed an issue where tooltips might unexpectedly appear on top of the Start menu icon in the taskbar when using the taskbar in an alternate position. Also fixed a few other visual polish issues when using the taskbar with small icons.

The digital safety of users and supporting families is central to how we think about the Windows experience. We're improving information on parental controls and their availability during Windows setup, so families can more easily understand available protections and make informed choices from the very beginning.

Update: The emoji panel (Windows key + period (.)) now uses GIPHY as the GIF provider, delivering a smoother GIF browsing and sharing experience following the deprecation of Tenor.
Fixed an issue which was causing the mouse cursor to potentially move in the wrong direction in recent Insider builds on secondary monitors when set to portrait mode.

Adding recovery remote management plug-in for extending WinRE management capabilities for MDM providers

Fixed an issue resulting in audio not working for some Insiders after the latest flights.

Fixed an issue impacting the reliability of Settings > Apps > Installed Apps after the latest flights.

If you were experiencing freezes in the previous flight when interacting with search, Notepad, or certain other scenarios, that should be resolved now.

When using dark mode, if you open "Run new task" from Task Manager it will now show in dark mode too.

Updates are based on Windows 11, version 25H2 via an enablement package (Build 26300.8687).
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.
For Windows Insiders who want to be the first to try new features, see the available list of features to toggle on at the Feature flags page under Settings > Windows Update > Windows Insider Program.
The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
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.
