Office Product Key Free: A Comprehensive Guide

The license files provided by KMS Host Service recognize KMS Host keys for Office, Project, and Visio. These files are essential for running the downloaded installer (office2016volumelicensepack_4324-1002_en-us_x64.exe, office2019volumelicensepack_x64.exe, or Office2021VolumeLicensePack_x64.exe) as an administrator on your KMS server.

To install the license files, you need to download the x86 or x64 version of Office Volume Licensing depending on the bitness of Windows on the host. Microsoft offers four types of Volume License Packs: Microsoft Office 2013 Volume License Pack, Microsoft Office 2016 Volume License Pack, Microsoft Office 2019 Volume License Pack, and Microsoft Office LTSC 2021 Volume License Pack.

You can download the latest Office Volume License Pack from the Microsoft Download Center using the following links. However, you need to install two versions of the Volume License Pack and two Office KMS Host keys on the KMS server.

Before installing the license files, make sure that the computer intended for use as a KMS server meets the system requirements listed on the supported Operating System versions. For instance, you cannot activate Office 2013 on a KMS server with only the KMS Host key for Office 2019 installed.

To activate the Volume License Office version (Project or Visio), you must have a configured KMS host. This MS Office version is subscription-based and can be activated online only. This guide applies only to Microsoft Office 2021/2019/2016 under volume license, excluding Microsoft 365 Apps for enterprise (ex-Office 365 ProPlus).

Configuring a KMS Host Server

To activate Office 2021 LTSC Volume License version, you can add support for the new version of Office to your KMS activation host. Enterprise customers can begin deploying the new Office 2021 LTSC on their computers side by side with previous versions of Office.

The LTSC version is designed for organizations with computers that do not want to receive feature upgrades or connect to the Internet. This version is also suitable for customers who do not want to obtain the Microsoft 365 subscription-based version of Office.

In October 2021, Microsoft released the new non-subscription version of Office LTSC 2021 (along with Windows 11). A corporate KMS server makes it easy to activate volume editions of Microsoft products (such as Windows and Office) in an internal or isolated enterprise network without the need to provide direct access to Microsoft's Internet activation servers for clients, and without using phone activation.

In summary, obtaining free office product keys requires downloading the correct Volume License Pack and KMS Host key for your specific version of Office. By following these steps, you can activate your MS Office 2021/2019/2016 under volume license.
