Microsoft Word 2021 Free Download Guide [Free Product Key]

Everything comes to a standstill when you realize that Microsoft Word 2021 is missing when a last-minute essay is due or a client proposal needs editing. Word 2021, a component of the Office 2021 suite, delivers more than just cosmetic updates; it introduces in-line commenting, a refreshed interface, and improved offline performance. Yet with Microsoft shifting focus to subscription-based models, the road to Microsoft Word 2021 free download has become unclear for many. So in this guide, I’ll lay out exactly how to access it without paying, which product keys still work in 2025, and why a free alternative like WPS Writer is gaining serious traction.

Latest Features in Microsoft Word 2021

Using Microsoft Word 2021 over the past few weeks, I noticed small but meaningful changes that made writing and editing smoother. It still feels familiar, but there’s a noticeable polish that makes everything flow better. I loved how the newer tools integrated seamlessly into my usual routine without needing a learning curve. The interface is more dynamic, and certain tools like in-line comments and offline editing work better. These tweaks didn’t make themselves known right away, but they’ve definitely improved the quality of my work.

The main highlights include:

• Real‑time co‑authoring: Collaborate live with others on the same document, seeing each other’s changes almost instantly.

• Visual refresh: Modernized UI with monoline icons, rounded corners and a cleaner ribbon aligned with Windows 11 aesthetics

• Automatic cloud saving: Files are stored to OneDrive or SharePoint, changes are saved in real time, reducing data loss risk

• Dark Mode: Includes a dark canvas in addition to dark toolbars, reducing eye strain during long editing sessions

• Updated Draw tab: new inking tools like Point Eraser, Ruler, Lasso, plus Sketched‑style outline and expanded stock media library

With the Microsoft Word 2021 free download, you get access to a more collaborative, visually polished, and user-friendly experience than previous versions.

How to Download Microsoft Word 2021 for Free with Free Product Key

Microsoft Word 2021 isn’t sold as a standalone app anymore, it only comes bundled with the full Office 2021 suite. If you already own a valid product key (from a past purchase, for example), you can reinstall the entire suite and activate Word without needing to buy it again. Getting it up and running took a bit more effort than I expected. I had to double-check that my system could handle it and that I wasn’t missing any steps that might set back the activation later. Between the setup tools and product key inputs, there’s definitely some fine print to work through.

System Requirements

Installing Word 2021 is only worth it if your system can keep up. I did a quick check to avoid wasting time or running into errors later. These are the requirements you’ll want to meet.

• Operating System: Windows 10 or later, or the three latest versions of macOS

• Processor: 1.6 GHz or faster, 2-core processor (Windows) | Intel or Apple Silicon (Mac)

• RAM: 4 GB (64-bit) or 2 GB (32-bit) minimum

• Storage: At least 4 GB of available disk space

• Display: 1280 x 768 resolution (Windows) | 1280 x 800 (Mac)

• Graphics: DirectX 9 or later with WDDM 2.0 (Windows)

• Internet: Internet access required for installation and activation

Free Product Keys for Microsoft Office 2021

If you’ve lost access to your original license but still want to explore Word 2021 free download legally, some older product keys still activate Office on certain systems. These keys usually come from educational bundles, previously bundled devices, or older purchases that haven’t been tied to a Microsoft account yet. Below are some publicly shared keys that may still work for activation.

• W269N-WFGWX-YVC9B-4J6C9-T83GX

• X4XQN-VMKJH-7TCVD-TB3QT-KTPKM

• 6F4BB-YCB3T-WK763-3P6YJ-BVH24

• YQGMW-MPWTJ-34KTH-PT9J9-9DQH7

• JNRGM-WHDWX-FJJG3-K47QV-DRTFM

• FCMXC-RDWMP-RFGVD-8TGPD-VQQ2X

• 9BX8T-K6H9V-BJ8XH-6RGXW-2J4CM

• HGNMT-D4T2T-3B9P9-RHHYC-XK3B4

While some of these keys may work, you should avoid any third-party software claiming to "crack" activation, as it may contain malware or violate Microsoft’s terms of service. If you're searching for “how to download Microsoft Word 2021 free”, it's safer to use a trial version from the official site or go with a trusted alternative like WPS Writer.

How to Download Word 2021 from Microsoft Office 2021

I didn’t want to tamper with dubious sources, so I stuck to the official route. The MS Word 2021 download through Microsoft’s site took a few extra clicks, but at least I knew I wasn’t installing junk. It took just a tiny bit more effort to download Word 2021 from Microsoft's website, but at least I knew I wasn't installing unnecessary software. As long as your product key is valid, it’s just a matter of following their setup instructions.

Step 1: Go to Microsoft Office Customization Tool’s website and start by selecting your system architecture under the “Architecture” section. You’ll see two options:

• x64: Best for most modern 64-bit systems, offering better performance for large files.

• x32: Ideal for older or 32-bit systems.

Step 2: Scroll down to the “Product and Release” section and select Office Suite as “Office LTSC Professional Plus 2021 – Volume License”. This version includes Word 2021 and other core Office apps.

Step 3: Next, move to the “Language” settings and select “Match Operating System (Machine Language)” as the default option. This ensures that your Word 2021 installation matches your system’s existing language settings.

Step 4: Once all your settings are in place, click the blue “Export” button in the upper-right corner of the customization tool to download the file to be used in the installation process.

Step 5: Now, head over to the official Microsoft Office Deployment Tool’s download page and click on “Download”.

Step 6: Run the “officedeploymenttool_16731-20290” file that you just downloaded to extract the tool’s files.

Step 7: Click the search bar in the taskbar and type Command Prompt. When it appears in the results, right-click and select “Run as Administrator” to open it with elevated permissions.

Step 8: In Command Prompt, type the following command and press “Enter” to allow the tool to download and install Word 2021:

setup.exe /configure Configuration.xml

Step 9: After installation, open Word and select the option that says “Enter product key instead”.

Step 10: After carefully entering the free product key you have, hit “Activate”. If the key is valid, you’ll see a success message and MS Word 2021 will be ready to use.

How to Download Microsoft Word 2021 for Free from Third‑Party Websites

After sorting through Microsoft’s official options, I got curious about other ways people still manage an MS Word 2021 free download, especially those who’d lost access but already had a license. Turns out, some older forums and archive sites still host clean, original ISOs. You just have to know where to look and double-check you’re not downloading something harmful in the process.

Step 1: Go to Download.it’s official website and click on the green "External Download" button to begin downloading the ISO file for Microsoft Word 2021.

Step 2: Once the ISO file finishes downloading, right-click on the file and select “Mount” from the context menu. This will create a virtual drive on your PC and allow you to access the contents of the ISO without needing to burn it to a disc.

Step 3: Inside the mounted drive, right-click the “Setup” file and select “Run as administrator”. The installation process will begin, and within a few minutes, Microsoft Word 2021 should be ready to use on your system

Best Free Alternative to Microsoft Word 2021 – WPS Writer

Once I’d installed Microsoft Word 2021 on my main laptop, I realized I still needed a solid word processor on an older PC that couldn’t handle the system requirements. I started looking for free alternatives that wouldn’t feel cumbersome or omit essential features. That’s when WPS Writer kept showing up, it was recommended across various forums and download sites. I was skeptical at first, but it opened my .docx files without breaking formatting and offered tools like track changes, comments, and even cloud sync. It wasn’t just usable, it was actually reliable enough to become my daily editor on that machine.

Features:

• Tab-style document management: Open multiple documents in a single window using tabs, no messy taskbar or managing multiple windows.

• AI-powered writing assistance: Built-in grammar checks and AI suggestions help tighten up your writing on the go.

• Free cloud storage with WPS Cloud: Sync your documents across devices and access them anytime with 1GB of free cloud space.

• Supports multiple file formats: Open, edit, and save in .doc, .docx, .pdf, .txt, and even .odt, no converter needed.

Once I was done skimming through everything it claimed to offer, I wanted to see how WPS Writer would actually perform when put to use. The installation barely took a few minutes, and before I knew it, I was already drafting a document. If you're used to Microsoft Word 2021 for Window/Mac and considering switching over, here’s the exact setup process I followed.

Step 1: First, open your browser to visit WPS Office and click the "Free Download" button to start the download.

Step 2: The download will finish in a few seconds. Once done, run the installation file like you would for any other app or software.

Step 3: WPS Office will show you a few simple terms and conditions. Accept them, then click the "Install" button to begin the installation.

Step 4: After installation, on WPS Office, click on “Docs” from the left panel, then select “Open” to open a document in WPS Office.

Step 5: Once the blank document is open, you can start typing your content and use the various tools available in the toolbar to make edits.

Step 6: After finishing your work, click on the “File” menu in the top-left corner, then select “Save As” to save your document locally on your device.

I used WPS Writer for about two weeks to draft articles, format reports, and even convert some documents into PDFs. Compared to Smartsheet, which feels more like a project management tool than a writing platform, WPS was cleaner and more focused on actual word processing. What stood out most was how lightweight it was; even with several documents open, my system stayed fast. It ticks all the boxes for students, freelancers, and small teams looking for dependable document creation without a subscription fee.

Comparison of WPS Writer and Microsoft Word 2021

After using both for serious writing, WPS Writer for article drafts and Word 2021 for academic documents, I noticed some clear differences that go beyond surface-level features. Word 2021 still wins when it comes to advanced formatting tools, integration with Microsoft’s ecosystem, and long-form document management. But WPS Writer surprised me with its speed, built-in PDF handling, and how well it ran on a mid-range laptop without lag. Below is a side-by-side comparison based on daily-use scenarios like platform support, co-authoring, and templates.

WPS Writer holds its own in compatibility and ease of use, with most essential features available free. While Word 2021 edges ahead in co‑authoring power, stock media, and editing intelligence, WPS provides far stronger value for zero cost.

Words Without Limits with WPS Writer
