Central Point Desktop is an alternate Windows 3.1 shell included with PC Tools 2.0 for Windows. It starts up instead of the Program Manager and offers a number of features that Microsoft didn’t implement until much later or even at all.

CP Desktop has a customizable top bar (with an optional toolbar), with “file item” icons (basically shortcuts) on the desktop. It’s hidden here, but there is a drive list that gives easy access to the drives in the system, and there is a status bar called “CrashGuard” at the bottom which monitors Windows resources.

Multiple desktops are available via the “MultiDesk” feature. By default there are four desktops (the purposes of which should be at the very least semi-obvious), and you can change between them by double-clicking on it’s window on the MultiDesk bar. They can also be changed through the drop-down menu on the top bar.
Opened applications will only be seen on that particular desktop, which basically is the whole point.

Dragging and dropping an item to a different window will move that item to the corresponding desktop.

The Main desktop contains icons for Program Manager groups and other things imported during setup.

Unlike later versions of Windows these files and folders do not actually exist in the file system, rather they are stored in a database that is updated by CPD.
Folders can be found within folders, and items can be viewed in Icon, Text, List or Toolbar views.

This is the PC Tools desktop, which contains all the programs installed by the PC Tools installer.
Also shown here is the File Management application, which allows you to do typical tasks as you would do with a computer in those days.
