What’s new on Windows 11 build 28020.1495

These are the most significant changes being rolled out in the latest preview of Windows 11 for the Canary Channel:

Start menu: Resolved an issue where the shutdown warning dialog’s edge could be cut off by the Start menu when other users were still signed in.
Input: Fixed a problem that caused a black flash when using a pen to ink in the Snipping Tool.
Power: Addressed an issue in recent Canary builds where shutdown could appear to restart on some Insider devices.
Settings: Fixed a loading hang on the Windows Update settings page and resolved an issue preventing English (Australia) language features under Time & Language > Language & Region from downloading.
Other: Fixed a bug causing IRQL_NOT_LESS_OR_EQUAL bugchecks for a small number of Insiders, related to certain smart card readers.

Microsoft is also noting a known issue that is causing open windows and tabs in File Explorer to jump to the Desktop and Home at the same time.

It is 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.
