New features and changes[edit | edit source]

DockingController application[edit | edit source]

DockingController was used as an application for Surface tablets to switch between tablet mode and desktop mode.

Network icon on the notification taskbar[edit | edit source]

When the user clicks on the network icon on the taskbar in the notification area, the network settings open in the PC settings that do not depend on the Charms sidebar that were in Windows 8 and 8.1.

This may be a reference that a new network flyout which fits with the new design of Windows 10 was planned. An iteration of the new network flyout can be seen in build 10009, though a placeholder with the "Hello World" text was found in earlier builds.

Bugs[edit | edit source]

Timebomb[edit | edit source]

Like other Windows 10 builds found in the fbl_partner_eeap branch, this build contains a non-functional timebomb and as a result can be installed on the current date.

Message boxes[edit | edit source]

Some message boxes, including the winver and "About Program" dialogs aren't properly resized. As a result, most of the buttons are missing.

Window thumbnail border color error[edit | edit source]

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 or restarting Windows.
