Evaluate Microsoft 365 for Ongoing Updates and Cloud Features
Best for users who need cross-device compatibility, large cloud storage, and continuous feature updates.
Microsoft 365 is a subscription service (billed monthly or annually) that ensures you always have the most up-to-date modern productivity tools from Microsoft.
Microsoft 365 includes 1 TB of OneDrive cloud storage per user, which is ideal if you frequently back up large files or photos across multiple devices.
If multiple people in your household need Office apps, the Microsoft 365 Family plan allows you to share the subscription with up to five other people, significantly reducing the cost per person.
A single Microsoft 365 subscription allows you to install and sign in to fully featured apps on PCs, Macs, tablets, and mobile phones simultaneously.
Choose Office 2021 for a One-Time Cost
Best for users who prefer to pay once and use the software on a single computer without recurring fees.
Try WPS Office for Your Personal Use
If you want to avoid expensive one-time licenses or monthly subscription fees, WPS Office offers a completely free, lightweight, and highly compatible alternative to Microsoft Office.
- 1. Download and Install: Visit the official WPS website to download the free installation package for your operating system.
- 2. Open Existing Office Files: Double-click your existing Word, Excel, or PowerPoint files to open them directly in WPS Office without losing formatting.
- 3. Edit and Save Seamlessly: Edit your documents and continue saving them in standard Microsoft formats to easily share them with others.

Frequently Asked Questions
Does Office Home and Student 2021 include Outlook?
No. Office Home and Student 2021 only includes Word, Excel, and PowerPoint. If you need Outlook for personal use, you must purchase Office Home and Business 2021 or subscribe to Microsoft 365.
Are the free Microsoft Office web apps good enough for personal use?
For basic document editing, the free web versions of Word, Excel, and PowerPoint are often sufficient. However, they lack advanced formatting features, macro support, and require a constant internet connection to function.
How can I avoid buying fake Microsoft Office licenses?
Always purchase software directly from the official Microsoft Store or a reputable authorized retailer. Avoid heavily discounted, unlicensed product keys sold on third-party marketplaces, as they can be disabled by Microsoft at any time.
Can I upgrade from Office 2021 to a future version for free?
No. Office 2021 is a one-time purchase, meaning it does not include upgrade options. If you want to upgrade to the next major release (such as Office 2024), you will need to pay the full price for the new version.
