Windows 11 Insider Preview Build 26085 was recently released to the Canary and Dev Channels. It brought many changes and improvements, including issues with the most popular games.

The Redmond tech giant has mentioned an important note for gamers in the Insider blog:

Most popular games should work correctly again in the most recent Insider Preview builds in the Canary and Dev Channels.

They also urged you to submit feedback in Feedback Hub on any issues you face while playing games on the latest builds.

Microsoft also mentioned that the company is investigating reports of rollbacks with error code 0xC1900101 while installing the latest build.

They are also informed that they are working on a fix for an issue in which some Insiders see File Explorer using the old design, and the tabs are also missing in the latest builds.

The new build temporarily turns off a new pointer indicator accessibility setting for low-vision Windows users. Microsoft introduced this feature with build 26052, and the company plans to enable it.

Furthermore, Insiders with Bluetooth LE Audio capable assistive hearing devices can set up and manage their devices through Settings>Accessibility>Hearing aids.

Here are the known issues and the fixes applied after the new build mentioned in the blog post:


  • Fixed the underlying issue believed to be the cause of shutdown and hibernation not working in the previous flight.

[File Explorer]

  • Fixed an issue where the context menu in File Explorer was missing an acrylic background.
  • Fixed an issue where when opening the context menu in File Explorer, the icons might appear out of place and overlapping text.
  • Fixed an issue which was causing File explorer to leak GDI objects and heap memory for every folder navigation, leading to stability and rendering issues over time.
  • Fixed a memory leak when interacting with archive folders in File Explorer.
  • Fixed an issue causing thumbnails in File Explorer to sometimes unexpectedly be black in the previous flight.


  • Fixed an issue believed to be the cause of the setting to enable sudo (under System > For Developers) not working for some Insiders.
  • Fixed an issue where if you ran the command “sudo pwsh”, it wasn’t working properly in recent builds.

[Windows Security]

  • Fixed a high hitting Windows Security app crash in the previous flight, which is believed to potentially be the cause of Insiders reporting that the Windows Security app icon in the system tray was sometimes missing in that flight.


  • With this build, the recent issues with the mouse cursor disappearing, and other recent issues related to the mouse cursor behaving abnormally should be fixed.


  • Fixed an underlying issue which was causing Settings to freeze sometimes so you couldn’t interact with any of the pages.
  • Fixed an issue where the list of Bluetooth devices under Bluetooth & Devices wasn’t being read out by screen readers in recent builds.

[Windows Update]

  • Fixed the issue causing Insiders in the Dev Channel to see error 0x80070002 when trying to install cumulative updates.
  • Fixed an issue where using “Update and Shutdown” wasn’t shutting down your PC upon completion.


  • Fixed an issue that was causing some Insiders to see bugchecks with CRITICAL_STRUCTURE_CORRUPTION recently.
  • Fixed an issue which was causing Voice Access to crash on launch for some Insiders in recent builds.
  • Fixed an issue where after renaming your printer, it might not work with print support app association.

The Windows Insider blog post also mentioned problems related to Copilot in Windows, including Voice access and Windows Ink. They also acknowledged the issues with Copilot resizing issues and missing bring focus to and refresh buttons.

Soon, all Windows features in the Canary and Dev Channels will be released for general availability. However, to experience them before the public release, you must join the Windows Insiders program.
