Release date: 1 May 2026
As a reminder, these release notes apply to those who are in the Canary 28000 series Channel. As we begin the transition to the updated Windows Insider Program, all new build release notes will be labeled under the new channel names, even though Insiders in the Canary 28000 series Channel may not yet find themselves having transitioned to Experimental (26H1). See the Windows Insider Blog for more details.
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.
[Windows Insider channel movement]
As announced in the Windows Insider Blog, we will begin moving users in the Canary 28000 Series Channel to the new Experimental (26H1) channel.
[Task Manager]
We’re making a few improvements to Task Manager:
- We’re updating Task Manager to provide better insight into NPU usage for PCs that include an NPU. New optional NPU and NPU Engine columns are now available on the Processes, Users, and Details pages. The Details page also adds NPU Dedicated Memory and NPU Shared Memory optional columns to give you deeper visibility into how workloads are using NPU resources. Additionally, if there are neural engines that are part of a GPU, they will now appear on the Performance page, providing a more complete view of AI‑related system activity.
- We’re also adding a new optional Isolation column to the Processes and Details pages, allowing you to see which apps are running in an AppContainer.
- Fixed accuracy of CPU speed display on the Performance page of Task Manager for VMs after resume from hibernate, so it doesn’t sometimes show unexpectedly high unrealistic numbers.
Once these changes are available to you, you can add any of the new columns by right‑clicking a column header in Task Manager and selecting them from the menu.

Reminder for Windows Insiders in the Experimental (26H1) channel (Currently transitioning from Canary 28000 Series Channel)
These builds can be unstable and may be released with limited documentation.
Features in the Experimental (26H1) channel 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.
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.
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.
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, report those issues to us via Feedback Hub.
