You can create an AutoIt script to either continually press an unused key (e.g. make it toggle the num lock, scroll lock), sleep for a minute or so, and repeat. Alternatively, if you use the keyboard a lot, you could make it move the mouse by a pixel or so in any direction.
If you don't want it continually running, you could also launch the script as a scheduled task (if you have access) to launch after the computer has been inactive for some time.
And this is a very simple script to perform an invisible mouse move, if you don't want to get into AutoIt syntax:
While True
Local $pos = MouseGetPos()
MouseMove($pos[0]-1, $pos[1]-1, 0)
MouseMove($pos[0], $pos[1], 0)
Sleep(540000)
WEnd
This script moves mouse cursor by one pixel in the up-left direction and after that returns it back, then sleeps for 9 minutes (540000
milliseconds). When script is running, you can see AutoIt icon in the tray. You can stop it right-clicking this icon and choosing the corresponding option.
To make a script, install AutoIt, right-click in any folder and choose New
> AutoIt v3 Script
, name it, right-click this new script, choose Edit
, paste the code provided above and save. You can even compile it to .exe
(again, from context menu) to start, for example, from Windows Scheduler.
