I've recently recompiled the Task Manager for Windows CE 5.0 devices. No installation kits are provided; the files below must be downloaded directly to the device, and placed into the \Windows folder. Thereafter, the Task Manager can be started by double-clicking the TASKMGR icon in the Windows folder.
For each device, just ONE executable file needs to be downloaded, the one that matches the device processor. Downloading the help file is optional.
Note that the Task Manager is not free; a license can be obtained by following the registration link in the main Task Manager page. Some functionality is available only to registered users.
