Findings[edit | edit source]

Hidden features[edit | edit source]

The following hidden features have been found within this build:

  • Hidden lock screen - enabled by setting Threshold to 1 under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\TestHooks] in the registry like in build 9845. It is quite buggy and it will auto login if there is no password set.
  • Enable XAML Start menu - create and set UseExperience to 1 under [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ImmersiveShell\Launcher]
  • Search box on the taskbar - enabled by setting EnableSearchBox to 1 under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Search

Bugs and quirks[edit | edit source]

Taskbar preview border color[edit | edit source]

If window auto-colorization is enabled, the taskbar preview borders do not change color even after the wallpaper changes. This issue can be remedied by manually changing the window color through the Control Panel or by restarting Windows.

XAML start menu[edit | edit source]

  • Sometimes, the user must click on the start button multiple times to bring up the menu.
  • Under rare circumstances and due to its earliness, the XAML start menu is largely broken and unfinished with the inability to pin/change titles and a lot of placeholders.
  • The username in the XAML start menu will say "Groot" instead of the currently logged-in user's name; it is a placeholder that directly references the fictional Marvel Comics character of the same name.
