Select Start, Programs, Accessories, Accessibility, Accessibility Wizard. In the dialog box that appears, click the text you find most comfortable to read. Click Next twice, unless you want to change one of the selected options, then check any of the four statements that apply to you. Click Next, and follow along as the wizard asks you some questions, based on the statements you selected. For example, if you indicated that you have a hard time seeing things on-screen, you'll have the option to set a new scrollbar size, icon size, and color scheme. When you reach the end of the wizard, click Finish to keep the settings you've selected.
