Consult the [Microsoft documentation](https://learn.microsoft.com/en-us/office/ltsc/2021/overview) to make sure Office LTSC is right for your needs.\n\nFor information on bringing your own license (BYOL) of Microsoft Office to Google Cloud, see the [Microsoft Licensing FAQ](/compute/docs/instances/windows/ms-licensing-faq).\n\nBefore you begin\n----------------\n\nBefore you begin, make sure that you have the following:\n\n- Ensure that Office LTSC products are installed on a virtual machine (VM) with a Windows operating system, either Windows Desktop OS or Windows Server.\n\n- Microsoft requires that Office LTSC products from Service Provider License Agreement (SPLA) providers are activated over the internet directly against Microsoft servers. Make sure that your VM allows open internet access during the activation step. You can disable the internet after activation. For more information on installing and activating your licenses, see [Install the License Manager agent](/compute/docs/instances/windows/license-manager#install-activate).\n\nInstall Microsoft Office LTSC\n-----------------------------\n\nThe installation media for Microsoft Office LTSC products is available directly from Microsoft through the Office Deployment Tool (ODT). Follow the instructions to [install the Office LTSC installation media](https://learn.microsoft.com/en-us/office/ltsc/2021/deploy).\n\nWhen prompted for the `product_id`, make sure to select the SPLA version of the volume licensing. For Office LTSC 2021 Professional Plus, this is `ProPlusSPLA2021Volume`.\n\nUse your Microsoft Office licenses\n----------------------------------\n\nMicrosoft Office licenses from Google Cloud are activated and managed by License Manager. To enable your Microsoft Office licenses, follow the instructions to [get started with License Manager](/compute/docs/instances/windows/license-manager#get-started).\n\nBilling considerations\n----------------------\n\nThere are specific billing considerations that you must be aware of when using Microsoft Office licenses available from License Manager on Google Cloud.\n\n### Billed by calendar month\n\nMicrosoft Office licenses are billed by the calendar month in which they are authorized for access. Billing begins when you [create a License Configuration](/compute/docs/instances/windows/license-manager#create-license-configuration). Billing for License Manager is not prorated based on when in the month you create a License Configuration.\n\nWhen you deactivate your Microsoft Office License Configuration or reduce the number of licenses, you will still be responsible for the license usage of the current calendar month in which they are authorized. The reduction in your authorized number of users will take effect in the next calendar month.\n\nWhen you increase the number of licenses for an active Microsoft Office License Configuration, these changes will take effect immediately and be reflected in the current month's bill.\n\n### Authorized access versus actual access\n\nMicrosoft Office licenses are billed based on the number of users who are authorized to access the product regardless of the actual usage. You will need to purchase licenses for the total number of users who are authorized to access the VM regardless of whether they log into the VM or not.\n\nAuthorization of access for Microsoft Office begins the moment you [create a License Configuration](/compute/docs/instances/windows/license-manager#create-license-configuration). For this reason, make sure that the number of licenses is correct before creating your License Configuration, as you will be billed for this amount in the current calendar month.\n\n#### Enforced Limits and Overages\n\nLicense Manager does not support enforced limits on the actual usage of licenses. It is your responsibility to ensure that the number of users who actually access Microsoft Office does not exceed the number of users authorized for access.\n\nIf License Manager determines that the total count of users who access virtual machines with Microsoft Office exceeds the number of authorized users in your License Configuration, the additional number of users will be considered authorized for access and you will be billed for the additional licenses for that calendar month."]]
