This page is easier to read than most. Turning on high contrast does not help to darken the print on screen. Web searches show many people have trouble with print on screen that is too light. Many elderly people have trouble. It would be helpful if Microsoft could provide a facility for darkening the print without having to go to Microsoft support. Offering white on black is not a solution.
