Maximus Mobile Task Manager is a free, new task manager for Windows Mobile 6.x devices. It basically allows users to easily switch between and close running programs. You can close one app at a time or all at once. In addition to managing open programs, it also displays how much memory is taken up by each running app and the amount of available/total RAM on your device. The managing window is scrollable and landscape mode is also supported.
After installing MMTaskManager, a shortcut is placed in your start menu for easy access. If you need even quicker access, you can also map it to one of your hardware keys.
