Windows 11 Insider Preview Build 25126 rs_prerelease (Dev Channel) 220521-1727

Good Morning friends! Microsoft has released a new preview build of Windows 11 25126 for members of the Windows Insider program using the Dev channel.

Complete build number: 10.0.25126.1000.rs_prerelease.220521-1727.


Improvements to the “Accounts” page in “Settings”

In October Microsoft updated the section “Settings” -> “Accounts”, adding the ability to view and manage Microsoft 365 subscriptions. In this build, the company is expanding the capabilities of this section. Now on this page you will be able to see all supported Office products with no expiration date such as Office 2021 and Office 2019 if they are associated with your account.

Thus, now in the “Settings” application, you will be able to see data about all supported Microsoft 365 and Office products licensed for your Microsoft account. The View Details button will provide you with detailed information about the product and will also allow you to quickly install Office on your computer.

Note. This change is currently not available to all Insiders in the Dev channel. The fact is that Microsoft wants to collect feedback from a small group of users before the change becomes available to all Insiders.


  • General:
    • We fixed an issue where some Insiders could encounter a GSOD with a DRIVER_IRQL_NOT_LESS_OR_EQUAL error referring to pci.sys, resulting in an inability to install up-to-date builds from the Dev channel.
    • We’ve made some changes to fix an issue where the Program Compatibility Assistant Service was causing unexpectedly high CPU usage. The issue was only seen by some Insiders after updating to the latest builds from the Dev channel.
  • Start menu:
    • The touch keyboard pinned to the screen should no longer close when trying to change the name of a folder in the Start menu.
  • Search:
    • Fixed a frequent crash in explorer.exe that occurred when using the “Search” function.
  • Options:
    • The preview image in Personalization -> Lock Screen should no longer be upside down when using an Arabic or Hebrew system.
  • Task Manager:
    • Task Manager should no longer hang if the explorer.exe process is hung.
    • We fixed an issue resulting in some Insiders having context menus in the Task Manager that didn’t match their chosen theme (light or dark).
    • Fixed a typo in the “Minimize on use” tooltip.
    • If you have hidden graphs in the sidebar of the Performance page, the color of the circles used instead should now match the color of the graph in the detailed summary.
    • We fixed an issue resulting in some processes not showing the Not Responding status on the Processes page.
  • Windows Sandbox:
    • Removed the “Lock” option from the Start menu as it doesn’t work.
  • Other:
    • We fixed an issue where using the “Open All Active Printers” option on a printer icon in the taskbar would open File Explorer if there was no active print queue.

Note. Some of the fixes listed above may be included in the cumulative updates for the October 5 release version of Windows 11.

Known Issues

  • General:
    • Some games that use Easy Anti-Cheat may crash or cause GSOD to appear on your device.
  • Live Captions:
    • Some applications do not allow you to display real-time subtitles in full screen mode. For example, this applies to video players.
    • Some apps at the top of the screen that were closed before Live Captions launched will re-launch behind the Live Captions window at the top. Use the system menu (ALT + ) when the application has focus to move the window down.

I wish you a successful update!
