New features and changes[edit | edit source]

Interface[edit | edit source]

The Windows Aero visual style has also been changed slightly and now features smaller caption buttons in certain dialogs.

Miscellaneous[edit | edit source]

  • The ReFS file system (codenamed Protogon) has been introduced in this build.

Bugs and quirks[edit | edit source]

  • This build uses the Arial font for the title bar and watermark instead of Segoe UI as a result of mistyping in the aero.msstyles and aerolite.msstyles files. This quirk persisted until build 7899.
