Which apps are included in Office 2021 Standard?
Office 2021 Standard includes six desktop apps: Word, Excel, PowerPoint, Outlook, OneNote and Publisher. Access isn't included; it is only in Professional Plus. Microsoft has announced that Publisher will no longer be supported after October 2026, so plan ahead if you rely on it.
| App | What you use it for |
|---|---|
| Word | Documents, letters, reports and CVs |
| Excel | Spreadsheets, budgets, formulas and charts |
| PowerPoint | Presentations and slide decks |
| Outlook | Email, calendar and contacts |
| OneNote | Notes, notebooks and to-do lists |
| Publisher | Flyers, newsletters and print layouts |
What's the difference between Office 2021 Standard and Professional Plus?
The only app difference is Access: Professional Plus includes it and Standard doesn't. If you never build or open Access databases, Standard already gives you every other app. Both Office 2021 editions include Publisher.
| Office 2021 Standard | Office 2021 Professional Plus | |
|---|---|---|
| Word, Excel, PowerPoint, Outlook, OneNote | Included | Included |
| Publisher | Included | Included |
| Access | Not included | Included |
| Runs on | Windows PC | Windows PC |
| Payment | One-time purchase | One-time purchase |
A question we often get is whether Standard can open Access files. It can't: .accdb databases need Access, which only Professional Plus includes.
Should you choose Office 2021 Standard or Microsoft 365?
Choose Office 2021 if you want to pay once and keep the same apps on one PC. Microsoft 365 is a subscription: it adds new features regularly, OneDrive storage and installs on several devices, but you pay every month or year. With an older release like Office 2021, also check the support dates below before you buy.
This key is for one PC. If you need the same edition on several computers, the 2, 3 and 5-key packs give you one separate key per PC.
Is Office 2021 still supported by Microsoft?
Office 2021's end-of-support date is 13 October 2026, for both the Windows and Mac versions. From that date, Microsoft no longer releases security updates, bug fixes or technical support for it. The apps keep working, but if you want a version supported until 2029, choose Office 2024.
Office 2021 still suits buyers who need to match an existing setup, for example an office where every PC runs the same version. For a new installation, Office 2024 gives you the longest remaining support period.
What are the system requirements for Office 2021 Standard?
You need a Windows 11 or Windows 10 PC with a 1.1 GHz dual-core processor, 4 GB of RAM and about 4 GB of free disk space. Office 2021 Standard doesn't run on macOS; Mac users need a Mac edition of Office.
| Component | Minimum requirement |
|---|---|
| Operating system | Windows 11 or Windows 10 (and supported Windows Server versions) |
| Processor | 1.1 GHz or faster, 2 cores |
| Memory (RAM) | 4 GB |
| Storage | 4 GB of free disk space |
| Display | 1280 × 768 resolution |
| Internet | Needed for installation and activation |

How do I install and activate Office 2021 Standard?
Download and install Office using the link in your order email, then enter your 25-character product key when an Office app asks for it. Before you start, uninstall any older Office version or Microsoft 365 trial.
- Uninstall any previous Office or Microsoft 365 versions from Settings → Apps.
- Download Office 2021 Standard using the link in your order email.
- Run the installer and wait for all the apps to finish installing.
- Open Word or Excel. When asked, enter the product key from your email.
- Check activation under File → Account. It should show "Product Activated".
The most common activation problem we see is a leftover Office or Microsoft 365 installation, often a trial that came preinstalled on a new PC. Remove it, restart the PC and then install Office 2021 Standard.
Frequently asked questions
Is Office 2021 Standard a one-time purchase?
Yes. You pay once, with no subscription, and the apps keep working. Keep in mind that Microsoft's end-of-support date for Office 2021 is 13 October 2026. From that date, it gets no further security updates, so Office 2024 is the better choice for long-term use.
Does Office 2021 Standard include Access?
No. Access is only included in Office 2021 Professional Plus. Standard gives you Word, Excel, PowerPoint, Outlook, OneNote and Publisher. If you need to create or open Access databases (.accdb files), choose Professional Plus instead.
Can I install it on a Mac?
No. Office 2021 Standard is for Windows only. Mac users need a dedicated Mac edition of Office, which uses a different product key. The Mac editions include Word, Excel, PowerPoint, Outlook and OneNote, but not Access or Publisher.
Can I move Office to a new PC later?
This key is for one PC. If you replace your computer, contact our support team with your order number first. Whether a transfer is possible depends on the licence type, so ask before you uninstall Office from the old PC.
