Disable changing accessibility settings

User Configuration\Administrative Templates\Windows Components\Internet Explorer

Prevents users from changing accessibility settings. If you enable this setting, the Accessibility option on the General tab in the Internet Options dialog box in the user interface appears dimmed. If you disable this setting or do not configure it, users can change accessibility settings, such as overriding fonts and colors on Web pages. You do not have to enable this setting if you use the Disable the General Page Group Policy setting (located under User Configuration\Administrative Templates\Windows Components\Internet Explorer\Internet Control Panel) because the Disable the General page setting removes the General tab from the user interface.
