Bugfixes[edit | edit source]

  • Keyboard focus will no longer get lost when pressing Esc after opening the user profile flyout in Start.
  • Addressed an issue that was causing Notification Center to get stuck in a state in recent Nickel builds where it would stop launching.
  • After bringing up an app's jump list from the Taskbar, right-clicking on the app name should now show the correct icon for Pin to Start (a pin icon).
  • Left and right-clicking the taskbar at the same time should no longer crash explorer.exe.
  • Fixed an issue where the command bar was doing unnecessary calculations when navigating to folders, causing an unexpected decrease in performance.
    • This is also believed to be the root cause of performance issues when using drag to select files, as well as using the arrow keys to navigate in certain folders.
  • The "Show hidden items" option should no longer get out of sync when multiple File Explorer windows are open.
  • Addressed an issue that Widgets board may appear empty.
  • Addressed an issue that Widgets may be displayed in the wrong size on external monitors.
  • The recent searches flyout when hovering over the search icon in the Taskbar should no longer immediately dismiss on invocation if an admin window is in focus.
  • Setting focus to the search box in File Explorer shouldn't make the touch keyboard invoke and immediately dismiss now when using a tablet with the Taskbar set to auto-hide.
  • Mitigated a memory leak that could occur in ctfmon, causing unexpected resource usage over time.
  • Addressed an issue for a small number of users that was causing textInputHost.exe crashes when setting focus on any text field.
  • Fixed an issue that was causing Settings to crash when radio buttons were updated.
  • Improved performance of loading the themes displayed in Personalization Settings.
  • If a non-admin user changes their display language in Language Settings, the system will no longer show the clickable sign-out button there as it was popping a UAC dialog and causing confusion.
  • Address an issue where "Media streaming options" in the Network and Sharing Center would unexpectedly revert to default settings after an upgrade.
  • Improved Quick Settings launch reliability.
    • This change should also help address the issue causing the window to not fully render (just a thin rectangle).
  • Addressed an issue where the media controls area in Quick Settings wasn't bringing the app displayed to the foreground in certain cases when clicking it.
  • Fixed an issue where the colors for items in Quick Settings could get stuck and not reflect the proper color for that state, particularly when using a contrast theme.
  • Opening the page for managing audio endpoints in Quick Settings should no longer cause a brief cut in audio playback when multiple devices are listed.
  • Mitigated an issue related to using Alt+Tab very quickly that could make explorer.exe crash.
  • Holding down Alt and pressing F4 after pressing Alt+Tab will no longer crash explorer.exe.
  • Fixed a casing issue that was causing LP.cab files to be unexpectedly removed in certain cases, which could lead the display language changing until users added the desired display language back in Settings.
  • Addressed an issue that was causing some users to see a bugcheck with error KERNEL_SECURITY_CHECK_ERROR.
  • Mitigated an issue that was causing the SysMain service to use an unexpected amount of power in recent Nickel builds.
  • The missing display order in BCD settings should no longer cause an upgrade failure.
  • Fixed an issue that was causing captions to draw at the wrong offset in certain apps.
  • Mitigated an issue that was causing crashes related to audiosrv.dll.
