Open any Office app, such as Word, and create a new document.
Go to File > Account (or Office Account if you opened Outlook).
Under Product Information, choose Update Options > Update Now.
Note: You may need to click Enable Updates first if you don't see the Update Now option right away.
Close the "You're up to date!" window after Office is done checking for and installing updates.
You can also use the Update Options button to Disable Updates or to View Updates that were previously installed.
