Hello all, I just brought a new laptop, Toshiba Satellite C850 today and I think I made a mistake with my start menu display. When I went to PC settings, then clicked on Start screen background so I could play around with colours it will not let me. The screen said that I am in high contrast which disables my ability to go into personalization settings. I'd appreciate any advise on how to disable the high contrast settings so I could play with the start screen background preset colours? Many thanks.
