New features and changes[edit | edit source]

Widgets[edit | edit source]

The sign-in requirement for Widgets has been removed. Therefore, users can now access the Widgets board without signing into a Microsoft account. This change can be toggled on manually by enabling the 41561445 and 41561454 velocity IDs.

Settings[edit | edit source]

  • The "Quick assistance from a friend" link has been added to the bottom of System > Troubleshooters.
  • A new option "Automatically manage color for apps" has been added under Display > Advanced display to turn on Auto Color Management for SDR displays. This feature is disabled by default, but can be toggled on manually by enabling the 41740192 velocity ID.

Miscellaneous[edit | edit source]

  • The performance of launching the search window in certain cases has been improved.
  • The text in Wireless Display has been updated to prompt users to turn on the input if it's not enabled.

Boot environment[edit | edit source]

The CIMFS device type which has been present but unimplemented since an unknown build is now implemented.

  • Therefore, the CIMFS filesystem which was present since an unknown build but unusable due to requiring a device of type CIMFS which could not be created, is now usable.
  • An attempt to create or open a device of type CIMFS will wipe all derived BitLocker keys and cap PCR11 if it was not already capped.

Bugfixes[edit | edit source]

General[edit | edit source]

  • Fixed an issue that was causing Windows Web Experience Pack to be missing after upgrading to build 25252 in certain cases, thus causing explorer.exe to get stuck in a crash loop and preventing Widgets and Windows Sandbox from working properly.
  • Fixed an issue that was causing certain PCI devices (such as secondary drives) to not work properly with errors in Device Manager.
  • Fixed an issue where users would need to press ← Backspace after typing to see search results for .cmd, .exe or .bat files.

Shell[edit | edit source]

  • Fixed an issue where, with the system tray design updates, auto-hiding the taskbar would stop working after users had interacted with the hidden icons flyout.
  • Fixed an issue that was causing a gap between full screen windows and the taskbar on secondary monitors.
  • Fixed an issue that was causing the system tray area to shift as the numbers change in the clock.
  • Fixed an issue that was causing the top half of the media controls in Quick Settings to be missing sometimes.
  • Fixed an issue that was causing the Microsoft Account sign-in window to have a black title bar in certain cases when using light mode.
  • The following fixes will only apply if the new search box on the taskbar is enabled:
    • Fixed an issue where the search box would not show up on multiple monitors as expected when clicking on either one.
    • Fixed an issue where clicking the search box would cause it to momentarily flash before the Search page displayed.

File Explorer[edit | edit source]

Fixed an issue that was causing explorer.exe to crash when opening certain items from the Recent section.

Task Manager[edit | edit source]

  • The data content area of the Processes page may flash once when theme changes are applied in the Settings page.
  • The Task Manager may not display light and dark content correctly with unreadable text when the "Choose your mode" option under Personalization > Colors in the Settings app is set to Custom.

Widgets[edit | edit source]

  • On right-to-left locales, the content may animate out of view before the Widgets board resizes when clicking to expanded view of the Widgets board.

Safe mode[edit | edit source]

  • Enabling the search box/icon on the taskbar may cause explorer.exe to hang or crash.
  • Quick Settings and date/time clock on the taskbar may be missing due to the Capability Access Manager Service service not running.
  • Clicking Bluetooth & devices and Personalization pages may crash the Settings app due to an overrun of a stack-based buffer 0xc0000409.
