The updated energy saver icon in the system tray and Quick Settings, initially implemented in build 26052, has been reverted to its old style which was first seen in build 26020.

Bugfixes[edit | edit source]

Fixed a DWM crash that was causing the screen to flash black.
Fixed the issue that prevented the ability to bring focus to the ellipsis or Refresh buttons by using a keyboard if the undocking experience for Copilot is enabled.
Fixed the issue that was causing shutdown and hibernate to not work on certain devices in the latest builds starting from 26080.
Fixed an issue that was causing the 0x80240067 error when downloading app updates from Microsoft Store or Windows updates in the Settings app.

Bugs and quirks[edit | edit source]

General[edit | edit source]

Users may be unable to perform an in-place upgrade to this build via Windows Update in builds 26040, 23620 and earlier due to a deadlock that occurs during the initial preparation process.

Shell[edit | edit source]

Text on highlighted items in Microsoft Management Console and some of its snap-ins may have a yellow color.

Copilot[edit | edit source]

Copilot may run automatically at startup unexpectedly after restarting Windows.
Voice access and Windows Ink may not work reliably if the undocking experience for Copilot is enabled.
When Copilot is docked and resized to a large width, it may not always fill the width of the panel. Resizing Copilot to less than half of the width of the screen usually fixes this issue.
