Frequently Asked Questions

Can I view Word documents without an active product key?

Yes. Unactivated Microsoft Office applications generally allow you to view and print documents in 'read-only' mode, but you will not be able to edit or save changes until you provide a product key or use a free alternative suite.

Is Microsoft Office Home & Student a recurring subscription?

No, Office Home & Student is a perpetual license. You pay a one-time fee to use Word, Excel, and PowerPoint indefinitely on a single computer, completely bypassing the need for a monthly Microsoft 365 subscription.

How do I know if my school offers a free Microsoft Office license?

You can verify this by visiting the Microsoft 365 Education website and entering your student email address. Alternatively, contact your school's IT administration desk to ask if desktop app licenses are provided for students.

Will free office suites alter my Microsoft Excel formulas?

Most premium free alternatives like WPS Office maintain excellent compatibility with standard Microsoft Excel (.xlsx) files, meaning your basic and advanced formulas will function properly without any modification.
