What is IceWM?
In Unix computing, IceWM is a window manager for the X Window System graphical infrastructure, written by Marko Maček. It was coded from scratch in C++ and is released under the terms of the GNU Lesser General Public License. It is relatively lightweight in terms of memory and CPU usage, and comes with themes that allow it to imitate the UI of Windows 95, OS/2, Motif, and other graphical user interfaces.

IceWM is available in [current] and therefore easily installable:
# pacman -S icewm
Installing MenuMaker from [extra] is also recommended:
# pacman -S menumaker
Although IceWM configuration is originally text-based, there are GUI-based tools available, notably icewm-utils in [community].
MenuMaker is a python script that automatically populates your applications menu based on what is installed in your system. This means programs from other desktop environments (KDE, etc.) can be run within IceWM. When running MenuMaker, use the -f flag to overwrite an existing menu file:
# mmaker -f icewm
Although some themes are included be default, there is a much larger and better selection in the verified icewm-themes package in the repository. Although many have a spartan, 'old Windows' feel, some (ElbergBlue, liquid, etc.) have a more modern look.
