Windows 8.1 build 9600.16596 (winblues14 gdr lean.140114-0237)

Windows 8.1 build 9600.16596 is a build of the Spring 2014 update for Windows 8.1.

Between January 22 and January 25, 2014, Russian and Chinese websites Win8China   and WZor.net  released several screenshots of this build documenting its new features, some revolving around the new right-click context menus and minor changes to the Metro/File Explorer interface. This build later leaked onto the Polish WinClub forums on February 2, 2014 under the x64 architecture.

The most notable change of this build is the ability to pin Metro apps onto the taskbar.

Changes from previous builds

 * Ability to pin modern apps to taskbar (Store pinned by default).
 * Search and shutdown buttons on the start screen.
 * This PC, Documents, and Pictures are pinned on the start screen by default.
 * Instead of metro bars (top and bottom) a context menu appears when you right-click an app on the start screen.
 * Apps now divided by the first letter in the "All Apps" view.
 * Internet Explorer 11.0.3 (with Enterprise Mode).

Internet Explorer Enterprise mode
The Internet Explorer included in this build doesn't have Enterprise mode enabled by default. To get it to work, create a DWORD HKLM\SOFTWARE\Policies\Microsoft\Internet Explorer\Main\EnableEnterpriseModeMenuOption and set it to 1. After that, launch F12 tools and in the Emulation section, go to Browser Profile and select Enterprise.
