To use KMS, you need to have a KMS host available on your local network. Computers that activate with a KMS host need to have a specific product key. This key is sometimes referred to as the KMS client key, but it is formally known as a Microsoft Generic Volume License Key (GVLK). Computers that are running volume licensing editions of Windows Server and Windows client are, by default, KMS clients with no extra configuration needed as the relevant GVLK is already there.
If you want to activate Windows without a KMS host available and outside of a volume-activation scenario (for example, you're trying to activate a retail version of Windows client), these keys will not work. You will need to use another method of activating Windows, such as using a MAK, or purchasing a retail license. Get help to find your Windows product key and learn about genuine versions of Windows.
If you are converting a computer from a KMS host, MAK, or retail edition of Windows to a KMS client, install the applicable product key (GVLK) from the list below. To install a client product key, open an administrative command prompt on the client, and run the following command and then press Enter:
Most software that you buy directly from Microsoft, like Office, Windows, and Xbox games, comes as a digital download that you can download, install, or reinstall. After you purchase software, the download will be shown in your Order history. To find a specific download, sign in to the Order history page with the Microsoft account you used to make the purchase. Find the software, and then select Product key/Install.
If you don't see Install, select the product name. It will take you to the product page. If the button that was previously labeled Buy is now Install, select it to automatically download and install your app or game.
If you bought boxed software that we shipped to you, Order history can't store the product key until you install the software for the first time. Follow the installation instructions that came with the boxed software.
If you have a subscription for Azure AD Premium P1 and above, or an edition of Office 365 Enterprise E3 or Office 365 A3 or Office 365 GCC G3 and above, you can use group-based licensing with Azure AD. You can assign one or more product licenses to a group, and Azure AD ensures that the licenses are assigned to all members of the group. Any new members who join the group are assigned the appropriate licenses. When they leave the group, those licenses are removed. For more information, see Group-based licensing in Azure Active Directory.
Microsoft 365 Apps communicates with the Office Licensing Service and the Activation and Validation Service to obtain and activate a product key. Each day, or each time the user logs on to their computer, the computer connects to the Activation and Validation Service to verify the license status and extend the product key. As long as the computer can connect to the internet at least once every 30 days, Microsoft 365 Apps remains fully functional. If the computer goes offline for more than 30 days, Microsoft 365 Apps enters reduced functionality mode until the next time a connection can be made. To get Microsoft 365 Apps fully functional again, the user can connect to the internet and let the Activation and Validation Service reactivate the installation, though in some cases the user may have to sign back in first.
Users can install Microsoft 365 Apps on a new device without being prompted to deactivate it on another device. If a user has more than 10 devices with Microsoft 365 Apps activated, then the device that hasn't been used for the longest amount of time is automatically deactivated.
After you download the Office Deployment Tool, double-click on the officedeploymenttool executable (.exe) file to extract the ODT files. When you're finished, you should have several files: setup.exe and some sample configuration.xml files. For an Office 2019-specific sample, see Sample configuration.xml file to use with the Office Deployment Tool.
Once you have a copy of the ODT, you need to create a configuration.xml file. You can create multiple configuration.xml files to be used with the ODT. For example, you would create a configuration.xml file to download and install the 64-bit version of Office Professional Plus 2019 in English and a different configuration.xml file to install the 32-bit version of Visio Professional 2019 in French. When you run the ODT from an elevated command prompt, you specify which configuration.xml file to use.
Instead of using a text editor to create your configuration.xml, we recommend that you use the Office Customization Tool (OCT). The OCT provides a web-based interface for making your selections and creating your configuration.xml file to be used with the Office Deployment Tool. For more information, see Overview of the Office Customization Tool. Please note that this is different than the Office Customization Tool that you might have used in the past to install volume licensed versions of Office that used Windows Installer (MSI) as the installation technology.
If you're not familiar with the Office Deployment Tool, it's usually used to customize deployments of Click-to-Run versions of Office products, such as Microsoft 365 Apps. For more information, see Overview of the Office Deployment Tool. 041b061a72
