-It's even possible to run the KDE desktop environment on Windows.
+It's even possible to run the KDE desktop environment on Windows,
+since KDE uses the cross-platform Qt framework.
+
+    The KDE on Windows Initiative is an ongoing project to port the KDE
+    applications to MS Windows. Currently supported versions of Windows are XP,
+    Vista and 7.

+This is not without difficulties, however.
+
+    The current implementation of KDE is designed in a unix specific way, which is
+    partially different from the Windows way. Examples for this are:
+
+    * Process creating - Using the Unix way of fork and exec.
+
+    * It isn't available on Windows, this difference requires a redesign of the related parts.
+
+    * Its missing Windows api counterparts.
+
+    * KDE uses Unix domain socket for high speed data transfer betwen kioslave
+      slaves and its parent process and for the communication to/from the dbus
+      deamon. On Windows there are no Unix domain sockets. They could be emulated
+      by tcp sockets with the costs of slower bandwidth and additional patches to
+      deal with Unix domain socket files exchanged between processes.

-However, ultimately Microsoft controls the Windows API,
-such as how low-level libraries ``user32.dll`` and ``gdi32.dll`` respond to function calls.
-As a result, Microsoft can exert control over the Windows desktop environment,
-such as making it `impossible to disable the dwm window manager`_ on Windows 8.
+There is Windows software for
+tiling window managers, [#tiling_window_managers]_
+virtual desktops, [#virtual_desktops]_
+and special effects to rival Compiz. [#cube_desktop]_

-Projects like Wine are something of a threat to this control,
-since it provides an open-source implementation of libraries such as ``user32.dll``.
+Given all these choices and customization options,
+what functionality could Windows possibly lack?
+
+Here is the problem:
+the Windows API determines the behavior of libraries like
+``user32.dll``, ``gdi32.dll``, and ``comctl32.dll``.
+Everything in hardware goes through the Windows API,
+including keystrokes, mouse clicks, and graphics.
+However, Windows must also obey licensing requirements,
+such as copyrighted content protection.
+This means that it is difficult to, say,
+replicate the Flip3D program.

+
+Something like `Wine`_ could, in principle, work around this,
+since it provides an open-source implementation
+of libraries such as ``user32.dll``.
 Perhaps that's why `Windows rejects a registry with the Wine configuration key`_.

-The Linux kernel does not require a particular desktop environment,
-or indeed any graphical desktop at all.
-However, Linux desktop users generally run graphical user interfaces managed by the X server.
-There are are many, many options
-for `desktop environment`_ and `window manager`_ on Linux.
+Another example: on Windows 8,
+it is impossible to disable the dwm window manager.

+    In Windows Vista and Windows 7, desktop composition is disabled in a number of
+    scenarios. In Windows 8, DWM desktop composition is a core operating system
+    component and cannot be disabled. With a few exceptions, desktop composition is
+    always on; it’s started before the user logon and remains active for the
+    duration of a session.

+    I  understand the choice and it improves the overall experience, but it is
+    going to force us to retire some of our older software, and it tool many years
+    to overcome the problems caused.

+Linux also has an API,
+but it is not tied to the desktop environment,
+and is not controlled by a single corporation
+in the same way that the Windows API is.
