New features and changes[edit | edit source]

User interface[edit | edit source]

Task View[edit | edit source]

The Task View has received the ability to have more than one desktop at a time, and can now properly close applications.

Notification Center[edit | edit source]

The Notification Center can now also be enabled and opened starting with this build; however, a majority of its functionality is not implemented and will therefore only detect incoming notifications via its respective taskbar icon.

Metro applications[edit | edit source]

Native support for windowed Metro apps is now enabled by default.

Hidden features[edit | edit source]

Search[edit | edit source]

This build includes a nonfunctional Search utility, which is disabled by default. It can be enabled by merging following registry setting and restarting File Explorer:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search]
"EnableProactive"=dword:00000001

Unlike in other builds, enabling Search in this build will only display a blank space instead of a search icon

Task View[edit | edit source]

The Task View isn't enabled by default yet, so the user has to enable it manually by merging the following registry key and restarting Explorer:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MultiTaskingView\AllUpView]
"Enabled"=dword:00000001

Bugs and quirks[edit | edit source]

Timebomb[edit | edit source]

Like other builds found in the fbl_partner_eeap branch, this build uses a test-signed certificate and as a result can be installed on the current date. However, installing this build on the current date disables the ability to change the desktop wallpaper in the Control Panel.

Control Panel[edit | edit source]

The System Properties page may incorrectly report the total amount of installed and usable RAM found on the machine as a result of using decimal values for size calculation. Other areas, such as the Task Manager will show the correct RAM amount.
