Microsoft Office 2021 was released alongside Windows 11 on October 5, 2021. This is the latest version of Office Suite, currently available for one-time purchase to consumers in various segments of the market.  

Having to download and install Microsoft Office can be tricky for some people, as there are various options and methods. This post guides you through the different processes involved, from purchasing a license for Microsoft Office 2021 to getting it activated on your machine.

If you are looking to invest in the latest Office Suite, this is the place to be. Let’s discuss the benefits of having Office 2021, rather than subscribing to Microsoft 365.

Why Choose Microsoft Office 2021

Obtaining Office 2021 gives you access to classic applications like Word, Excel, PowerPoint, Outlook, OneDrive, Publisher, Access, etc. This is a one-time purchase, which means you only need to pay once to get a valid product key for Office 2021, unlike Microsoft 365 which needs to be renewed every month/year (depending upon the type of subscription).

Microsoft Office helps you keep getting creative with the different tools and keeps your work organized. You can then share your work with your friends and colleagues to collaborate on projects and get productive.

Office 2021 comes in different editions. The following editions are available to choose from:

  • Office Home & Student 2021
  • Office Professional 2021
  • Office Professional Plus 2021

Each of these offers a different set of tools, and you can pick one that best suits your work type.
