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 is continuously working to fix these vulnerabilities by offering updates, patches and service packs. These fixes are offered free of charge to licensed versions of Microsoft Office.


Once you're ready to install the necessary fixes for your version of Microsoft Office, you will need your Microsoft Office CD. You should also have your product key number in case you are asked to supply that information.


Once you have downloaded and installed the necessary updates, go back to Microsoft's Office Updates site and check for updates again. Keep checking until there are no further updates, patches or security packs to install.
