Mouse Jiggler is a tiny application that will move the mouse on your screen. Do not worry, it will move it just a few millimeters, only to prevent actions that may occur after a period on inactivity, such as screensaver appearance. If you ask yourself hat is a mouse jiggler, than the answer is that is a modality of automatic move of your mouse.
The interface has 2 options to enable or disable the function. A second option named "zen jiggle" will not move the cursor visually, only in the background or virtually.
In other words, this is a fake mouse user.
Mouse Jiggler is available as free download for Windows 32-bit and 64-bit.
