Never again do you need to worry when Office stops working for no apparent reason. All the Office programs are now self-repairing, which means that Office checks to see if essential files are missing or corrupt as a program opens and fixes the files as needed. You may never even realize there was a problem. Other times, Office starts fine but might have another problem, such as a corrupted font file or a missing template. These kinds of problems used to take hours to identify and fix. Now Office does the work for you with the Detect And Repair feature, which locates , diagnoses, and fixes any errors in the program itself. If you need to add or remove features or remove Office entirely, you can use Office Setup's maintenance feature.
