- Device & OS

- Scenario
- Purchasing and installing Microsoft Office applications for local, offline use on a single computer.
- Observed behavior
- Seeking a clear comparison between Microsoft 365 (Personal/Family) and Office Home & Business to make an informed purchasing decision based on feature updates and cloud storage needs.
Before purchasing, determine whether you need ongoing feature updates across multiple devices or if you prefer a single upfront payment for lifetime access on just one computer.
Opt for Office Home & Business for a One-Time Purchase
Best for users who want to pay once and only need core applications on a single PC without ongoing feature updates.
Office Home & Business 2021 is a traditional, one-time purchase. You pay a single upfront cost to get core applications like Word, Excel, PowerPoint, and Outlook for one computer.
It receives necessary security updates to keep your system safe, but it does not receive new feature upgrades over time. This makes it a cost-effective choice for a permanent, local-only installation.
Ensure you only need the Office suite installed on one specific local PC or Mac, as the license cannot be actively shared across multiple computers.
Buy Office Home & Business 2021 from the official Microsoft Store or an authorized retailer.
Sign in to your Microsoft account, enter your product key, and download the standalone installer to set up the apps directly on your PC. Cloud storage is entirely optional.

Choose Microsoft 365 Personal for Ongoing Updates and Multi-Device Support
Best for users who want the latest features, cross-device installation, and included cloud storage.

Frequently Asked Questions
Do I need the internet to use Microsoft 365 if the apps are installed locally?
You need internet access to download, install, and initially activate Microsoft 365. Afterward, you must connect to the internet at least once every 31 days to verify your active subscription status. Between those checks, you can use the applications completely offline.
Does the one-time purchase of Office 2021 include OneDrive cloud storage?
Office Home & Business 2021 does not come with premium OneDrive cloud storage. You only get the standard free 5GB of storage that comes with any basic Microsoft account, but you can save all files directly to your local hard drive.
Can I install Microsoft 365 on multiple computers?
Yes. A Microsoft 365 Personal subscription allows a single user to install the Office applications on up to 5 devices simultaneously, including Windows PCs, Macs, tablets, and smartphones.
Which Office installation option is cheaper in the long run?
For a single computer over a period of 3-5 years, a one-time purchase (like Office Home & Business) is generally cheaper. However, it lacks continuous feature updates and multi-device capabilities, so the value depends on your specific productivity needs.
