It is possible that older screen readers will not function properly with Windows Live Essentials 2011.
If you are using Windows Vista or Windows 7 and you want to ensure that you aren’t automatically upgraded to Windows Live Essentials 2011, you can set the older version of Windows Live Essentials so that it runs in compatibility mode for Windows XP.
