Here is some crazy prank to do ta the office on your colleagues computer
(1) Go to Start-Control Panel-Mouse. It should open a window that says “Mouse Properties” at the top.
(2) Check the box that says: Switch primary and secondary buttons. This will make the left mouse button act like the right one and vice versa.
(3) At the top, select “Pointer Options”
(4) Move the indicator all the way to the left. This slows down the mouse.
(5) Go to “Wheel” (at the top) and set the number of lines to scroll with one click to 100 (or high as it will go).
have fun but be sure to inform them later on…..
