Look at Task Manager when it's gone and then when it's there.
Also, make a Speccy report when it's gone and then another when it's there. Compare what's running.

My husband has a Lenovo laptop running Windows 10. An Icon appearing to be a touchpad with a line diagonally through it will appear in the center lower portion of the screen. He can reboot the computer and it will disappear for a while but then reappears. There doesn't seem to be anything turned off relating to the touchpad. We can't figure out what triggers it to come on. If anyone has had this problem and has resolved it we would greatly appreciate any information
