Insider KB5102951 Windows 11 Insider Experimental (26H1) build 28120.2387 - July 6

As a reminder, these release notes apply to those who are in the Experimental (26H1) channel.

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.

[Taskbar]​

• Alternate Taskbar Position
  • You can now change the position of taskbar on your screen. In Settings > Personalization > Taskbar > Taskbar Behaviors, you can select the side of the screen you want your taskbar on: bottom, top, left, or right. In these other positions, tooltips, flyouts, and animations will still come from the taskbar, and most customization settings like small taskbar and never combine taskbar icons will work with all locations.
  • Support for touch gestures, Search box, and Ask Copilot in alternate locations is in progress. Auto-hidden taskbar and touch optimized taskbar are not yet supported.

• Smaller Taskbar
  • We're introducing a smaller taskbar for users who want to maximize screen space, especially on smaller devices. While the default taskbar remains unchanged, this setting provides a more compact experience with smaller icons and a reduced taskbar height, giving you more room for your apps. Core elements like Start, Search, and the system tray scale appropriately to stay aligned and consistent.
  • To change your taskbar size, go to Settings > Personalization > Taskbar > Taskbar behaviors > Show smaller taskbar buttons. When set to Always, both the icons and the taskbar height become smaller.

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

• These builds can be unstable and may 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 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.
