What are Microsoft Office updates? Why do I need them?

Microsoft Office has been -- and still is -- a target for hackers and viruses because of its security vulnerabilities. To combat this, Microsoft releases frequent updates and security patches. The best way to ensure you receive these updates is to enable automatic updates for your Office products by using the Microsoft Update service.

• Enable automatic updates for Office on Windows or on macOS
• For Office 2010 and earlier - check whether updates are available
