Download
[File Explorer]
- We’ve improved the visual consistency and reliability of the Copy dialog in Dark mode, including its launch experience and the expanded progress view.
[Start menu]
- Improved reliability of Start menu reflecting newly installed or removed apps without requiring sign-out or restart.
[Taskbar]
- Fixed an issue for Insiders using the new smaller taskbar option, where the system tray might get cut off or pushed off screen.
[Settings]
- Improved reliability of Settings > Apps > Startup.
[Virtualization]
- This update addresses an issue that could result in bugchecks citing HYPERVISOR_ERROR (0x20001) and KMODE_EXCEPTION_NOT_HANDLED (0x1E) errors after installing the latest flights on some devices during system restarts, virtual machine operations, or while running some gaming applications.
Reminders for Windows Insiders in the Experimental channel
- Updates are based on Windows 11, version 26H2 via an enablement package (Build 26300.8697).
- 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.
