Office 365 and Microsoft 365 subscribers get more frequent software updates than those who have purchased Office without a subscription, which means subscribers have access to the latest features, security patches, and bug fixes. But it can be hard to keep track of the changes in each update and know when they’re available. We’re doing this for you, so you don’t have to.
Following are summaries of the updates to Office 365/Microsoft 365 for Windows, with the latest releases shown first. We’ll add info about new updates as they’re rolled out.
Note: This story covers updates released to regular Office 365/Microsoft 365 for Windows subscribers. If you’re a member of Microsoft’s Office Insider preview program or want to get a sneak peek at upcoming features, see the company’s “Release notes for Office for Windows Desktop (Beta builds)” page.
