In April 2010, Microsoft released Office 2010, the latest version of its Office suite. The McCombs School does not officially support Office 2010, and will continue supporting Office 2007.
Students wishing to upgrade to Office 2010 can contact the Campus Computer Store for information on purchasing the software at the student price.
