What you get with Office 2021 Home & Student
Office 2021 Home & Student is the 2021 home suite for one PC: Word, Excel, PowerPoint and OneNote, licensed by Microsoft for non-commercial use. It is a perpetual license, so there is no monthly or yearly fee. The order e-mail carries the product key, a link to the installer on Microsoft’s servers and short setup notes; your PDF invoice is attached to the order-completed e-mail.

What is new in the 2021 apps
- Excel 2021 adds XLOOKUP, which finds a value in any column of a table, and dynamic array formulas such as FILTER, SORT and UNIQUE that spill their results into neighboring cells.
- The LET function stores an intermediate result under a name inside one Excel formula, so long calculations stay readable.
- PowerPoint 2021 records a slide show together with your webcam video, ink drawings and laser pointer, and Ink Replay plays a drawing back stroke by stroke.
- In Word 2021, Dark Mode turns the document canvas dark as well as the toolbars, and Line Focus shows one, three or five lines at a time.
- Files saved to OneDrive can be edited by several people at the same time in Word, Excel and PowerPoint.
OneNote is included for notes, clippings and class material, and the apps open and save OpenDocument 1.3 files as well as the usual Office formats.
Home & Student or another Office edition?
This edition fits students, parents and anyone who writes, calculates and presents on a single home computer. It leaves out Outlook, Access and Publisher, and the license excludes commercial use. For an office PC, Office 2021 Professional Plus brings Outlook, Access and Publisher. The previous release, Office 2019 Home & Student, has the same four apps without the 2021 additions listed above. On a Mac, Office Home & Business 2021 for Mac is the matching suite and adds Outlook.

Questions about Office 2021 Home & Student
May I use Office 2021 Home & Student for paid work?
No. Microsoft sells Home & Student for non-commercial use, so freelance or company work belongs on an edition licensed for business, such as Office 2021 Professional Plus.
What is the Microsoft account used for?
The key is redeemed once and the license is then attached to that account. Later you reinstall Office from Services & subscriptions without typing the key again.
Is this the same Office as Microsoft 365?
No. Office 2021 keeps the feature set it was released with, while a Microsoft 365 subscription adds cloud storage and new features over time for as long as you pay for it.
