Announcing new builds for 15 May 2026

Wait 5 sec.

Hello Windows Insiders,Today we will be expanding the rollout of the new Windows Insider Program changes to devices in the Beta Channel, which will be moved to the new Beta experience. Please see the announce blog for more information about what this entails.New builds this weekToday we are releasing new Windows 11 Insider Preview Builds. As a reminder, all Insiders can find the release notes for your device based on the new channel system, even if you haven’t moved yet. This is to make finding build information as easy as possible during the transition. See your channel release notes here: Beta: Build 26220.8474 Experimental: Build 26300.8493For those on other specific build versions, here are today’s new builds and release notes: Experimental (26H1) – Including Canary 28000 series: Build 28020.2134 Experimental (Future Platforms) – Including Canary 29500 series: Build 29591.1000As a reminder, you can always find your build number in the watermark on bottom right-hand corner of your desktop.Please note, existing Beta Channel Insiders on Windows 11 version 26H1 are currently getting the same build version as Experimental (26H1). In the coming weeks we will be releasing separate builds for these channels, which is when we will have a new Beta (26H1) release notes section. Additionally, Insiders who move to the new Beta experience and are on the default 24H2 core version, and who elect to move to version 26H1 under the WIP settings Advanced options, will experience a delay in their device up taking the new version during this transition.Notable new features:[Taskbar improvements]Release channel: ExperimentalAlternate Taskbar PositionYou 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.[caption id="attachment_178963" align="aligncenter" width="1024"] Screenshot of the taskbar in the left-aligned position.[/caption]Smaller TaskbarWe’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.See the in-depth blog for more information about Taskbar improvement.[Widgets]Release channel: ExperimentalAs we continue to make Widgets feel less distracting, we’ve made a small but meaningful visual update to taskbar badging. For those that have taskbar badging on, the badge color will now match your Windows accent color instead of always appearing red, reducing the sense of urgency that something needs your immediate attention.We’re also testing out quieting down a user’s experience based on their level of engagement. For example, a user who highly engages with Widgets likely have their settings set to a state that works best for them, as compared to a user who barely engages with it and would benefit from having the experience quieted down with taskbar badging turned off as it is for new users who experience it as quiet by default.[Windows Search Box]Release channel: ExperimentalWe've started making changes to make Windows Search Box more relevant, starting with making it easier to find your files and apps: Files and apps more reliably appear ahead of web suggestions when your content is a stronger matchYou can expect to see additional relevance improvements in upcoming releases.Thanks,Stephen and the Windows Insider Program team
