== Findings ==
=== Hidden features ===
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 ==
=== Taskbar preview border color ===
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 ===
* 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.
* Unlike the Mexican Spanish version, the XAML Start Menu is left untranslated in the Canadian French version.
=== Pseudo localization ===
* On certain international releases, some parts of the OS have Pseudo localized translations to some English text.
===Explorer shell===
*Launching the date and time flyout crashes Explorer.
*Launching the Autoplay dialog will cause the system to lock up. It is recommended to open removable drives manually via Explorer.
