New features and changes[edit | edit source]

Start[edit | edit source]

  • This is the first build to bring back the visible Start button after being absent since Windows 8 build 8186 (winmain).
  • An option to list desktop apps first in the apps view has been added.
  • New customization options for the Start screen have been added.
  • The default Start screen layout has been updated.

Navigation[edit | edit source]

This build adds several navigation-related options, the most notable being:

  • An option to disable active corners.
  • An option to go straight to the desktop when signing in.
  • An option to replace Command Prompt with PowerShell in the ⊞ Win+X menu.

Apps[edit | edit source]

  • Many apps have been updated to resemble their RTM counterparts.
  • Movie Moments has been removed.

Miscellaneous[edit | edit source]

  • The boot logo has been temporarily changed to a minimalist betta fish.
  • The OOBE has a new color picker, which is similar to the one found in the RTM.

Bugs and quirks[edit | edit source]

  • The states of Windows Recovery Environment recovery partitions created from earlier Windows installs are not migrated during system upgrades.
  • Some Radeon cards from the era cannot be used in this build due to the drivers failing the digital signature check. A workaround is to disable driver signature enforcement from the advanced boot options menu every time the machine starts up, or enable test signing.
