Office More Less Support for Office will end on October 13, and there will be no extension and no extended security updates. All of your Office apps will continue to function. However, you could expose yourself to serious and potentially harmful security risks.
Select the Microsoft Office product you want to repair, and select Modify. This will repair the entire Office suite even if it's just one application you want to repair such as Word or Excel. If you have a standalone app installed, then search for that application by name.
