Windows 11 build 29580
In the Experimental experience for Feature Platforms, the company is rolling out only general improvements and a new version of the Feedback Hub app, which brings a range of refinements based directly on Insider feedback.
This version improves overall reliability while introducing design and accessibility tweaks to create a more polished experience.
Microsoft has also enhanced localization support, including the ability to view non-English community feedback in English and to automatically translate collection titles and official responses into major languages.

Windows 11 build 28020.1921
As part of the Windows 11 build 28020.1921, Microsoft rolls out general improvements and fixes to improve the overall experience.
Also, in Task Manager, the company is introducing new improvements that give users deeper visibility into system performance and security-related activity.
For devices with an NPU, Task Manager now includes optional NPU and NPU Engine columns across the “Processes,” “Users,” and “Details” pages. The Details page also adds “NPU Dedicated Memory” and “NPU Shared Memory” columns, helping you better understand how AI workloads use system resources. If your GPU includes neural engines, these will now appear on the Performance page for a more complete view of AI processing activity.
Microsoft is also adding a new “Isolation” column in the “Processes” and “Details” pages. This makes it easier to see which apps are running inside an “AppContainer,” improving transparency around app isolation.
Once these updates are available, you can enable the new columns by right-clicking any column header in Task Manager and selecting them from the menu.
Other details
It’s important to clarify that Windows 11 26H1 is not a feature update for existing devices. The software giant has explicitly confirmed that version 26H1 is not an upgrade path for computers running Windows 11 25H2 or any earlier release.
This release is designed exclusively for new ARM64 hardware and will ship only on next-generation computers, starting with devices powered by Snapdragon X2 Plus, Elite, and Extreme processors. Systems based on Intel or AMD platforms will never receive Windows 11 26H1 through Windows Update or any other supported upgrade channel.
