Changes[edit | edit source]

  • The 3D Objects folder will no longer show by default in File Explorer starting with this build. To access it, type %userprofile% to access the user folder or enable the "Show all folders" option for the navigation pane.
  • The "Reduce taskbar updates" option for News and interests has been temporarily removed.
  • Most of the touch keyboard enhancements from builds 21301.1000 and 21313 were temporarily removed. Only the large-screen layout and candidate bar updates were kept.

Bugs[edit | edit source]

News and interests[edit | edit source]

  • The flyout may not be available when signing into an account without internet access. Reconnecting to the network will restore it.
  • Sometimes the flyout cannot be dismissed with pen.

General[edit | edit source]

  • The update process to this build has a chance of hanging for extended periods of time.
  • The reliability of the Start menu and other modern apps may be affected in this build.
  • Domain networks appear with the wrong firewall profile, which may block some local network services. As a workaround, configure the network as private to allow local network traffic.
  • Chinese text for the lunar calendar in the clock and calendar flyout is no longer displaying properly
  • Live preview doesn't work for pinned site tabs on some machines, a gray window is seen instead of the intended content.
  • When an Xbox controller is connected and the device is shutting down, restarting, or entering sleep, it may hang.
  • When launching some games, there is a chance that the system will crash with an HYPERVISOR_ERROR GSOD.
  • It is not recommended to install this build in devices with Bitdefender installed, as these may experience black screens and/or Windows Explorer crashes.
