Bugfixes[edit | edit source]

  • Fixed the issue that was impacting File Explorer launch reliability.
  • Fixed the issue that was causing the Japanese and Chinese IMEs to not work properly in certain apps, and to not work correctly in the File Explorer search box.

Bugs and quirks[edit | edit source]

  • Adjusting screen brightness may not work on some laptops.
