I turned my computer on to only realize my mouse is inverted but i never changed the option to invert my mouse. Now I can't find the option to change it.
Are you saying that the functions of Left click and the Right click are reversed.
i.e. Left click becomes Open and right click becomes Select ?
If yes, give this a try...............
In the search box, type control panel > Enter.
Select Mouse from the Control Panel > at the top, click Buttons > under configuration, is the box "Switch primary and secondary buttons" checked ?
If yes, UN-check it.
Click OK when done.
