Fixes: Tablet-optimized taskbar
  • Fixed the issue causing the taskbar to sometimes collapse when it should be expanded if there are no running windows on the desktop.
  • Fixed an issue that would occur when using the left or right edge gestures resulting in the Widgets or Notification Center (respectively) overlapping with or looking truncated by the taskbar.
  • Fixed an issue that was causing the tablet-optimized taskbar to crash explorer.exe while switching apps.
  • Fixed an issue that was causing the tablet-optimized taskbar to crash explorer.exe if you entered the overflow flyout.

Note: These fixes will not only show if you enable a tablet-optimized taskbar on your device.

  • Fixed an issue where when switching between windows in recent builds you might see the entire window flash black for a frame while rendering.

System Tray Updates

  • Fixed an issue so that Quick Settings items can now be rearranged with touch again

Note: These fixes will only show if you enable the System Tray Updates on your device. The tablet-optimized taskbar is still rolling out to Windows Insiders and is not yet available for everyone.
