How to Download Microsoft Office 2021 Professional Plus 64-bit

Downloading the Office 2021 Professional Plus 64-bit version can be a task questioned by many, which is why we have curated this guide with each individual in mind to ensure a smooth Office 2021 Pro Plus 64-bit free download process. From the preparation stage until you start using it, this section covers it all. So, let's get started on this somewhat time-consuming journey!


The process starts with uninstalling any previous Microsoft Office version that may be installed on your PC. After upgrading to Windows, around ten days later, your previous Windows version will be automatically deleted from your computer. However, if you wish to free up storage space and are confident that your files and settings are correctly configured in the current Windows version, you can proactively remove it manually.

Step 1: Press the key with the Windows logo on your keyboard to access the Start menu.


Step 2: From the Start menu, select "Settings" to go to the Windows Settings.

Step 3: Within the Windows Settings menu, select "System". This section houses a range of system-related configurations.

Step 4: Within the "System" menu, locate and click on "Storage". This will provide you with information about your computer's storage usage.

Alt text: Windows system storage settings

Step 5: Now, under the section that displays information about your hard drive, look for an option labeled "Temporary files" and click on this option.

Step 6: Within the "Temporary files" section, you'll find various checkboxes for different types of files that can be deleted to free up storage space.

Step 7: Among these checkboxes, you should see one that says "Previous version of Windows". This is the option you want to select.

Step 8: After selecting the "Previous version of Windows" checkbox, proceed by clicking on the "Remove files" button. Doing this will start the removal process.

System Requirements:

Ensure your system meets these prerequisites before downloading and installing Microsoft Office 2021 Professional Plus:

  • Dual-core processor running at 1.6 GHz.

  • Operating system: Windows 11 or Windows 10.

  • Memory: 4 GB RAM (for 64-bit version) or 2 GB RAM (for 32-bit version).

  • Storage: Minimum 4 GB of available hard drive space.

  • Display: Minimum screen resolution of 1024 x 768 or higher.

  • Graphics Card: DirectX 10-compatible graphics card for hardware-accelerated graphics features.


Next, you can proceed with the free download of Office 2021 Pro Plus 64-bit

Step 1: Visit the official MSKeySoft website.

Step 2: Choose your preferred language.

Step 3: Locate and click on the link that corresponds to "Office 2021 Professional Plus" to initiate the download of the installer file.


Step 1: Once the installer file has been downloaded on your system, locate and double-click to start the installation process.

Step 2: The installation wizard will initiate and may require additional component downloads, so please be patient.

Step 3: Click “Close” once the installation of Microsoft Office Pro Plus is completed on your system.

Downloading Microsoft Office Pro Plus can be a bit time-consuming, and it can be frustrating if you accidentally select the wrong language from MSKeysoft, as you'll need to start the process again.

How to Activate Office 2021 Professional Plus for PC(64-bit)

In this section, we'll explore two different methods to activate Microsoft Office Professional Plus 2021 for PC (64-bit).

Method1: Purchase a product key from Microsoft

Here's the step-by-step tutorial on how to activate Microsoft Office 2021 Professional Plus for PC (64-bit) if you already have a product key but don't have an account:

Step 1: Begin by going to the Microsoft Office official website.

Step 2: While on the website, find and select the "Create a new account" button.

Step 3: Proceed by entering your personal details to set up your own Microsoft Office account.

Step 4: After successfully signing in, you'll be prompted to input your product key.

Step 5: Click on "Next". Launch any Microsoft Office application installed on your computer, and select "Sign In" from the upper-right corner.

Step 6: Sign in using your newly created account credentials. Once signed in, all Microsoft Office applications on your computer will be automatically activated.

Method 2: Use KMSPico to activate Office 2021 Pro Plus

Alternatively, users can also activate their Microsoft Office 2021 Professional Plus using KMSPico. With KMSPico 10.2.2, you get an Office 365 Activator to swiftly activate Office 365/2019.

Step 1: Open your browser and visit KMSPico’s official website.

Step 2: Scroll down and download the KMSPico Activator by clicking on "Download KMSPico 11.2.1".

Step 3: You will be redirected to the download page, click on “Download” to initiate the download process.

Step 4: Once the file has been downloaded, users will need to unzip it. It's double-zipped to avoid detection by Windows Defender.

Step 5: Once the file has been unzipped, run the installation file. Please remember, that the file is password protected and the password is available in the “Password.txt” file inside the zipped folder.

Step 6: Run the KMSPico tool and wait for the user interface to load. The loading time may vary depending on the server load of Microsoft KMS Servers but should not exceed 30 seconds.

Step 7: Ensure that the Office logo is selected within the interface, and then click the red button to initiate the activation process.

Step 8: Your Office suite is now ready for use without any restrictions.

Please keep in mind that this activation method isn't permanent, as it utilizes KMS keys provided by Microsoft for software evaluation. These keys typically expire within 6-12 months, so you may need to reactivate Office 365 after this period. Feel free to save this page as a bookmark for future reference and updates.


The activation tokens are downloaded from official Microsoft servers. If you've previously blocked them in your HOSTS file, remove those entries to ensure reliability. Otherwise, a third-party server based on your location will be used.

If you have antivirus software installed, temporarily disable it for 10 minutes to allow the activator to modify System 32 files and write to the Windows registry.

Both methods are effective if the steps are followed correctly. However, activating Microsoft Office 2021 Pro Plus through their official website is much easier and straightforward. When attempting to run KMSPico on your system, there's a risk of it being detected by Windows Defender. In such cases, users may choose to disable Windows Defender temporarily. It's important to note that disabling Windows Defender can potentially expose users to security risks, so caution is advised.

ISO & IMG Files: What Are the Differences?

The differences between ISO and IMG file formats are important to understand when dealing with software downloads and archives. Both formats serve as archives, containing copies of the original disc's contents and file structure. Nevertheless, it's essential to be mindful of certain differences:

ISO File Format

IMG File Format

ISO is an international standard file format designed for disc images.

IMG format was initially designed for creating backup copies of floppy disks in a single file.

It holds a complete disc image, including the file system, within a single file.

IMG files store a bitmap of each written disk sector, with each sector being 512 bytes in size.

ISO files are widely used for archiving and distributing software, such as Linux installation CDs.

Since the decline of floppy disks, the IMG format has been adapted for hard disk image files.

Commonly used for creating CD and DVD images.

In essence, while ISO and IMG formats have their unique origins and purposes, they can be used interchangeably if the IMG file is uncompressed. This flexibility allows for compatibility with various software applications that may primarily recognize ISO files.
