Input[edit | edit source]

  • The reliability of the touch keyboard, IME candidate window, and IME toolbar have been improved.

Miscellaneous[edit | edit source]

  • The performance of showing up files and content as results in the search box has been improved.

  • If memory integrity in the Windows Security app cannot be enabled due to incompatible drivers, the information about which drivers are incompatible is now selectable.
  • The experience on logon after booting up has been improved by reducing the performance impact of startup apps.
