Microsoft 365 Personal and Microsoft 365 Family are subscriptions that include powerful productivity apps and creativity tools with AI-powered features. In addition to premium desktop versions of popular Microsoft 365 apps like Word, PowerPoint, Excel, and Outlook, you also get spacious cloud storage and cloud-connected features that let you collaborate on files in real time. With a subscription, you'll always have the latest features, fixes, and security updates along with ongoing tech support at no extra cost. You can choose to pay for your subscription on a monthly or yearly basis, and use your apps on multiple PCs, Macs, tablets, and phones. Office 2024 is a one-time purchase that comes with classic apps like Word, Excel, and PowerPoint for PC or Mac, and does not include any of the services that come with a Microsoft 365 subscription. One-time purchases don’t have an upgrade option, which means if you plan to upgrade to the next major release, you'll have to buy it at full price.
