1] Check for Mouse Gestures
There are certain mice that come with in-built gestures. The Task Manager might have been randomly popping up due to that. Disconnect the existing mouse and connect another one and check if it is happening. If it is not happening with another mouse, then it is problem with the mouse gestures.

If you have updated any program recently or installed any new programs on your PC recently after which you are seeing Task Manager popping up randomly, uninstall the updates or program. Check if the Task Manager is still opening randomly. If the problem is still not fixed, try the following methods.
