Before you begin
- Microsoft Office 2021 only works on Windows 10 or later. So, if you are using Windows 7/8, you will not be able to install it and Office 2016 is still a good choice for you in this case.
- To make sure that Office 2021 will work normally, we recommend you to uninstall your old version of Office completely before starting a new installation.
Download Microsoft Office 2021
Microsoft gives you a tool named Office Deployment Tool to download and install Microsoft Office apps. But using this tool could be difficult for standard users. You can get the details about the tool from Microsoft Learn.
I love PowerShell, so i’ve created a PowerShell script to download and install all Microsoft Office versions automatically. The benefits of using this method:
- Can be used to download Office 2013/2016/2019/2021 and Office 365 apps.
- Supports download and install both Office 32 and 64 bit.
- Supports multiple languages when installing Microsoft Office.
- Supports remove or uninstall all installed Office apps to do a clean install.
- The source for installation is getting from Microsoft’s servers with high speed and secure.
To download and install Microsoft Office 2021, you can follow the below steps:
1️⃣ Right-click on the Windows start icon then select Windows PowerShell (Admin) or Terminal (Admin) in Windows 11 to open an elevated PowerShell window.
2️⃣ Copy then run the below command to download Microsoft Office apps. My PowerShell script is safe, but you should verify the security and contents of any script from the internet you are not familiar with.

Conclusion
Hello Friends! My name is Leo, and I’m excited to share everything I know about activating Microsoft software products. In the past, I managed several YouTube channels on this topic, but they were taken down by Microsoft. That’s why I decided to start this blog to keep the conversation alive without interruptions. I’m committed to sharing my knowledge and insights for as long as possible!
If you would have any questions or concerns, please leave your comments or visit my Discord server. I would be glad to explain in more details. Thank you so much for all your feedback and support!
