Announcing Windows 11 Insider Preview Build 26300.8155 (Dev Channel)

April 4, 2026 admin

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 26300.8155 (KB 5083822) 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*

[Input]

Users will be able to feel haptic feedback effects on compatible input devices while performing certain actions, such as aligning objects in PowerPoint, window snapping, resizing, or hovering over the Close button. These haptic effects can be configured in Settings under Bluetooth & devices > Mouse > Haptic signals.

Feedback: Share your thoughts in Feedback Hub (WIN + F) under Input and Language > Mouse.

[Xbox mode]

Xbox full screen experience is now Xbox mode
We’ve added an improved first run experience when entering Xbox mode

Feedback: Share your thoughts in Feedback Hub (WIN + F) under Gaming and Xbox > Gaming Full Screen Experience.

[Other]

Improved performance of launching startup apps after boot (apps which display under Settings > Apps > Startup).
Fixed an issue resulting in certain apps not being able to sign in recently, citing an internal connection issue when internet was actually connected.
Fixed an underlying crash impacting some Insiders’ ability to print with the latest flights.

Reminders for Windows Insiders in the Dev Channel

Updates are based on Windows 11, version 25H2 via an enablement package (Build 26300.8155).
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.
