Changes

  • The kernel version is now 10.0 as opposed to 6.4 in previous builds. This change is so the kernel version of the operating system can match with its name.
  • Context menus are now more consistent and unified in this build.
  • The copyright date in winver has been updated from 2014 to 2015.

Hidden Features

  • 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 Windows 10/10.0.9926.fbl awesome1501.150119-1648. it is quite buggy and it will auto login if there is no password set.

Bugs

Window thumbnail border color error

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