Download and install MS Office 2021 full version for free with lifetime activation. It is also compatible with Windows 11, 10, 7, 32, and 64-bit operating systems.

What is Microsoft Office 2021?

Microsoft Office 2021 is a productivity suite that includes a variety of applications, services, and tools designed to help you get the most out of your work. The suite includes office apps like Word, Excel, PowerPoint, OneNote, Outlook, Publisher, and Access. It also includes cloud services like OneDrive and Skype for Business. Office 2021 is available for both Windows and Mac.

If you’re thinking about upgrading to Microsoft Office 2021, there are a few things you should know. First, the suite is only available as a one-time purchase. You can’t subscribe to it like you can with Office 365. Second, Office 2021 isn’t compatible with earlier versions of Office (like Office 2016). Third, the price for Office 2021 varies depending on which edition you choose: Home & Student ($149), Home & Business ($249), or Professional ($439).

So, is Microsoft Office 2021 worth the upgrade? That depends on a few factors. If you need the latest version of Office in order to stay compatible with colleagues or clients, then it’s probably worth the investment. However, if you’re happy with an older version of Office (or if you’re using a free alternative like LibreOffice), then there’s no need to spend the money on an upgrade.

How to Officially Install MS Office

Step 1: Obtain the ISO file

Purchase or download the Microsoft Office 2021 ISO file from the official Microsoft website or other authorized sources.

Step 2: Prepare your computer

Make sure your computer meets the minimum system requirements for Microsoft Office 2021.

Close any running programs and save your work.

Step 3: Mount the ISO file

On Windows 10 and later versions, right-click the ISO file you downloaded and select “Mount.” This will create a virtual drive that contains the ISO content.

Step 4: Start the installation

Open the virtual drive (usually labeled as a new DVD drive) created after mounting the ISO file.

Look for the setup file (e.g., setup.exe) in the virtual drive and double-click it to begin the installation.

Step 5: Enter the product key

During the installation process, you will be prompted to enter your Microsoft Office 2021 product key.

Type in the product key as provided to you upon purchase or download, then click “Next” or “Continue” to proceed.

Step 6: Choose installation options

Select the desired Office components you want to install. You can typically choose to install Word, Excel, PowerPoint, Outlook, and other applications as needed.

Customize the installation settings based on your preferences (if applicable).

Step 7: Install Microsoft Office 2021

Click “Install” or “Next” to begin the installation process.

The installation may take some time, depending on your computer’s performance and the components you selected.

Step 8: Complete the installation

Once the installation is finished, you will see a confirmation message or completion window.

Step 9: Activate Microsoft Office 2021

Launch any Office application, such as Word or Excel.

You will be prompted to activate the product.

Choose to sign in with your Microsoft account associated with your Office 2021 purchase or enter the product key again for activation.

Step 10: Update Microsoft Office 2021 (optional)

After the installation and activation are complete, consider checking for updates to ensure you have the latest features, security patches, and bug fixes.

Congratulations! You have successfully installed Microsoft Office 2021 using the ISO file. Now you can start using the Office applications for your productivity needs.

Who should upgrade to 2021?

If you’re a heavy Office user, the improvements in the 2021 version may be worth the upgrade for you. Some of the new features include:

  • Better support for high-resolution displays
  • Improved performance when working with large files
  • Improved grammar and style checking in Word
  • New templates and design options in PowerPoint
  • Improved collaboration features in Excel and OneNote

If you don’t use Office that much, however, you may not need to upgrade. The changes between the 2019 and 2021 versions are mostly cosmetic, so unless you really need the latest and greatest features, you can stick with what you have.

Who shouldn’t upgrade to 2021?

If you’re happy with the version of Microsoft Office you have, there’s no need to upgrade to the latest version. Office 2021 is largely the same as Office 365, with a few new features and minor improvements. Unless you’re desperate for the new features, it’s not worth spending the money on an upgrade.


So, is Microsoft Office 2021 worth the upgrade? While it depends on your individual needs and preferences, we think that the answer is generally yes. The new features and improvements included in this latest version make it a worthwhile investment for most users. If you’re still using an older version of Office, or if you’re thinking about making the switch from another productivity suite, then we recommend giving Microsoft Office 2021 a try.
