Bugs and quirks[edit | edit source]

Interface[edit | edit source]

Localization[edit | edit source]

  • Specific parts of the user interface (such as File Explorer strings, Metro applications and portions related to setup) are not localized and therefore use their English (United States) string resource counterparts.

Applications[edit | edit source]

  • Right-to-left orientation support in the reworked PC settings application is not complete and displays UI elements left-to-right despite proper localization being present.
  • The Xbox Music media player application fails to start properly on this build.
  • Certain Win32 applications such as Paint may not redraw themselves correctly.

Desktop Window Manager[edit | edit source]

  • DWM animation transitions (such as invoking the Charms bar) do not work properly.
