Office 365 is a subscription service that gives you the most up-to-date Office apps from Microsoft.
All Office 365 plans for home and personal use include the full apps you're familiar with, including Word, PowerPoint, and Excel, plus extra online storage, tech support, and more. Try it free for a month.
If your PC is running Windows 10 S, you'll need to install Office from Microsoft Store.
If you've already got an Office 365 subscription, you'll need the Microsoft account that's associated with your subscription to sign in and install or activate the Office apps, or to change your billing or other details of your subscription.
