New features and changes[edit | edit source]

Shell[edit | edit source]

An alternate loading animation of the taskbar has been added.

  • This feature is disabled by default. To enable it, run ViVeTool from an elevated Command Prompt window to enable the 39751186 velocity ID.

Miscellaneous[edit | edit source]

  • The timebomb has been extended from 15 September 2022 to 15 September 2023.
  • The Narrator's logic has been updated to explicitly narrate the OneDrive folder when navigating to it using the navigation pane in File Explorer.

Bugfixes[edit | edit source]

General[edit | edit source]

  • Fixed the issue that was causing certain devices with low disk space to encounter the 0x80070001 error in Windows Update when trying to install the latest build.
  • Fixed an issue that was causing FPS to decrease when playing certain games due to the wrong graphics card being used.
  • Fixed an issue which could cause the camera light on a laptop to get stuck on after logging in.
  • Fixed an issue believed to be the root cause of bugchecks when opening and copying files from network locations.

File Explorer[edit | edit source]

  • Fixed an issue causing the left-half of the File Explorer title bar to not be draggable via mouse or touch.
  • Fixed an issue causing Home, Documents, Pictures, and potentially other folders to become unexpectedly duplicated in File Explorer's navigation pane or appear on the desktop.
  • Fixed an issue where selecting multiple folders and then using the context menu option to open them in a new tab would unexpectedly open the first folder in a new tab and all the others in a new window.

Shell[edit | edit source]

  • Fixed an issue which could lead to the taskbar overflow flyout unexpectedly appearing on the opposite side of the screen.
  • Fixed an issue that was causing the animation on the taskbar that plays when a user switches from using a device in tablet posture to desktop while in overflow to incorrectly show when logging in.
  • Fixed an explorer.exe crash which could happen when determining if the taskbar overflow should display while switching out of a full screen game.
  • Fixed a Start menu crash that could prevent apps from launching from it.

Bugs and quirks[edit | edit source]

General[edit | edit source]

  • Some games that use Easy Anti-Cheat may crash or cause the device to bugcheck.
  • The audio may stop working in certain cases.
  • Several apps may crash on launch in certain cases.
  • Certain devices with Xbox Dev Kit installed may experience repeated explorer.exe crashes after attempting to access certain folders on Windows.

File Explorer[edit | edit source]

  • The color of the search box background may be the opposite color of the current color mode.
  • The Delete key may not work on files.

Virtualization[edit | edit source]

  • Users may experience a UNSUPPORTED_PROCESSOR bugcheck when booting Windows in VMware Workstation 16 on a Hyper-V enabled host with 2 or more cores allocated.
  • The system may fail to boot in VMware with attached network adapters.

Shell[edit | edit source]

  • The taskbar may not be able to display if File Explorer is maximized and the taskbar is set to auto-hide.
  • On some locales, the default font used in several UI elements (such as the date and time on the taskbar) may change to regular Segoe UI instead of Segoe UI Variable.

Widgets[edit | edit source]

  • The Notification badge number may appear misaligned on the taskbar.
  • The Notification banner for some badging may not appear in the Widgets board in some cases.

Print[edit | edit source]

Safe mode[edit | edit source]

  • 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.
