Join nowMicrosoft Office 2021 Home & Student is the straightforward, one-time purchase that puts classic desktop productivity back under your control. You pay once, you install it on your Windows PC, and you keep using Word, Excel, PowerPoint, and OneNote for as long as your device runs. There is no monthly fee, no annual renewal, and no feature freeze if you decide to skip an upgrade cycle. This perpetual licence is built for students writing dissertations, households managing budgets, freelancers running client projects, and anyone who simply wants a stable, offline-capable Office suite that does not depend on a recurring payment plan.
The big advantage is predictability. You know exactly what you are spending today, and you know the software will continue to work tomorrow. Microsoft delivers security and stability updates for the supported lifecycle of Office 2021, so your applications stay safe without forcing you onto a subscription. At Lizensa, your genuine licence key is delivered digitally within minutes, backed by a full EU warranty and a VAT invoice that makes accounting painless. If you have been holding onto Office 2016 or 2019 and wondering whether now is the right moment to move forward, this edition gives you modern functions like XLOOKUP and dynamic arrays in Excel, improved collaboration in Word, and better media handling in PowerPoint — all without a Microsoft 365 commitment.
When you complete your order at Lizensa, you receive everything needed to get Office 2021 Home & Student running on your Windows PC. Your purchase includes a genuine, pre-verified product key delivered by email, a direct download link to the official Microsoft installation source, and a clear activation guide that walks you through each step. You also receive a full VAT invoice that serves as your proof of licence ownership — essential for business accounting, warranty claims, and any future Microsoft compliance checks.
This is a perpetual retail licence, not an OEM key tied to a single motherboard, not a volume-activation MAK or KMS key intended for enterprise deployment, and not a Microsoft 365 subscription. It is the same licence type a consumer would purchase in a boxed retail product, delivered digitally. The licence is valid for the lifetime of the device on which it is activated; there is no expiration date and no renewal requirement. If you need to reinstall Windows or move to a new hard drive on the same machine, you can reinstall and reactivate using your original key. Licence transfer to a completely new PC is subject to Microsoft’s retail licence terms, which generally permit a limited number of transfers for genuine retail licences.
Activation is straightforward: download the installer from Microsoft’s official setup portal, sign in with or create a Microsoft account, enter the product key we provide, and follow the on-screen prompts. An internet connection is required during activation, but once complete, all applications work fully offline. The licence is valid across all 27 EU member states and works with any of the supported display languages, including English, German, French, Spanish, Italian, Dutch, Polish, and many others.
Choosing between Office editions often comes down to three questions: subscription or one-time purchase, which applications you actually need, and how long you plan to use the software before upgrading.
One-time purchase vs Microsoft 365 subscription: Office 2021 Home & Student is a perpetual licence. You pay once and use the software indefinitely on a single PC. Microsoft 365, by contrast, is a recurring subscription that includes ongoing feature updates, 1 TB of OneDrive cloud storage, and access to the latest version at all times. If you prefer predictable costs and do not need cloud storage or constant feature updates, the perpetual licence is the more economical choice over a three-to-five-year horizon. If you need the absolute newest features every month and work across multiple devices, a subscription may suit you better.
Which apps are included in this edition: Home & Student includes Word, Excel, PowerPoint, and OneNote. It does not include Outlook, Access, or Publisher. If desktop email management in Outlook is essential to your workflow, you should consider the Office Home & Business edition instead. For most students, home users, and freelancers who manage email through a web browser or a separate client, the Home & Student suite covers every core productivity task.
Who this edition is best for: This licence is ideal for university students, home-based professionals, families managing household finances and school projects, and small business owners who need reliable Office applications without adding another monthly expense. It is also a practical choice for IT buyers provisioning a fleet of devices where a fixed-version standard is preferred over subscription variability.
Compatibility with older Office versions: Office 2021 can coexist with older Office installations during a transition period, but Microsoft recommends uninstalling previous versions before installing 2021 to avoid file-association conflicts. Documents created in Office 2021 use the same file formats as Office 2016 and 2019, so sharing files with colleagues on older versions is seamless. If you are upgrading from Office 2013 or earlier, the jump in performance, security, and Excel functionality alone justifies the move.
Before purchasing, verify that your device meets the following minimum specifications. These are Microsoft’s published requirements for Office 2021 Home & Student running on Windows.
| Component | Requirement | | --- | --- | | Operating system | Windows 10 or Windows 11 (32-bit or 64-bit) | | Processor | 1.6 GHz or faster, 2-core processor | | Memory | 4 GB RAM | | Storage | 4 GB available disk space | | Display | 1280 × 768 screen resolution | | Internet | Required for download, activation, and updates | | Graphics | DirectX 9 or later with WDDM 2.0 driver for graphics hardware acceleration |
This edition is designed exclusively for Windows. It does not run on macOS, Linux, Chrome OS, or mobile operating systems. A Microsoft account is required for activation and for accessing any optional cloud-connected features, though local document editing works fully offline after activation.
Language support: Office 2021 Home & Student supports installation and use in over 20 display languages, including English, German, French, Spanish, Portuguese, Japanese, Polish, Dutch, Italian, Czech, Swedish, Danish, Finnish, Norwegian, Greek, Hungarian, Romanian, Slovak, Slovenian, Croatian, Bulgarian, Estonian, Lithuanian, and Latvian. You can switch the display language after installation, and the proofing tools for multiple languages are included.
Your licence key is delivered by email immediately after payment is confirmed — on average, in under 60 seconds. The email contains your unique product key, a link to the official Microsoft Office download page, and step-by-step activation instructions written in plain English.
To install, visit the Microsoft setup portal, sign in with your Microsoft account, and enter the product key when prompted. The installer downloads the correct version for your Windows system automatically. Once installation completes, open any Office application — Word, for example — and follow the activation prompt. The process typically takes less than 10 minutes depending on your internet speed.
If activation fails, the most common causes are entering the key incorrectly, attempting to activate on an unsupported operating system, or a temporary Microsoft server issue. Lizensa provides free multilingual technical support to help you resolve activation problems. In the rare event that a key is faulty, we replace it at no charge under our licence guarantee.
Reinstallation policy: You can uninstall and reinstall Office 2021 on the same device as many times as needed. If you replace your hard drive or reinstall Windows, simply use your original product key and Microsoft account to reactivate. For transfers to a new PC, Microsoft’s retail licence terms apply; contact our support team if you need guidance on your specific situation.
Lizensa has earned its reputation as a trusted software licence retailer across the European Union by focusing on what matters to buyers: genuine licences, instant delivery, and real support when something goes wrong. Every Office 2021 Home & Student key we sell is sourced through authorised European distribution channels and individually verified before it reaches your inbox. That means you are not gambling with a grey-market key that might work today and be deactivated tomorrow — you are buying a legitimate, audit-ready licence that stands up to a Microsoft compliance check.
Your purchase is protected by EU consumer law, including the 14-day right of withdrawal. If you change your mind before activating the key, you can request a full refund. We provide a proper VAT invoice with every order, and for B2B customers registered for VAT in another EU member state, reverse-charge invoicing is available. Checkout is secured by Stripe, supporting SEPA bank transfers, iDEAL, BLIK, Google Pay, and all major credit and debit cards, so you can pay the way that suits your local market. After your purchase, our multilingual support team is available to help with activation, reinstallation, or any licensing question — free of charge. When you buy from Lizensa, you are buying certainty.
It is a one-time, perpetual licence. You pay a single price and can use the software indefinitely on one Windows PC. There is no monthly or annual fee, and the applications do not stop working if you choose not to upgrade to a future version.
A retail licence, like the one sold here, is tied to the user and can be transferred to a new PC under certain conditions. An OEM licence is preinstalled by a manufacturer and permanently locked to the first device it is activated on. Lizensa supplies genuine retail licences, giving you more flexibility.
On average, the key arrives by email in under 60 seconds. The email includes your product key, download link, and activation guide. In rare cases of manual review, delivery may take a few minutes longer.
Yes. Every key is sourced from authorised European distribution and verified before delivery. You receive a VAT invoice that documents your licence ownership, and the key activates directly on Microsoft’s official servers.
Contact Lizensa support. Most activation issues are resolved quickly — common fixes include double-checking the key entry, ensuring Windows is up to date, or temporarily disabling VPN software. If a key is genuinely faulty, we replace it free of charge.
You can reinstall on the same device as often as needed, including after a Windows reinstallation or hard drive replacement. Transferring the licence to a completely new PC is subject to Microsoft’s retail licence terms; contact our support team for guidance on your specific situation.
No. Office 2021 Home & Student is a Windows-only application. It runs on Windows 10 and Windows 11 desktops and laptops. It is not compatible with macOS, iPads, Android tablets, or Chromebooks.
Outlook is not included. Home & Student contains Word, Excel, PowerPoint, and OneNote. If you need the desktop version of Outlook, consider the Office Home & Business edition, which adds Outlook to the same core applications.
We accept SEPA bank transfers, iDEAL, BLIK, Google Pay, and all major credit and debit cards through our Stripe-secured checkout. The available methods adapt to your location within the EU.
Yes. Every order includes a full VAT invoice suitable for business accounting and tax purposes. For B2B customers with a valid EU VAT number, reverse-charge invoicing is available.
Under EU consumer law, you have a 14-day right of withdrawal on digital purchases. If you have not yet activated the licence key, you can request a full refund. Once a key is activated, refunds are handled on a case-by-case basis in accordance with applicable law.
Microsoft provides security and stability updates for Office 2021 under its fixed lifecycle policy. Mainstream support typically lasts for at least five years from the release date. Check Microsoft’s official lifecycle documentation for the exact end-of-support date.
