Microsoft Volume licensing is Microsoft’s former platform for license distribution to businesses. Volume Licensing has now migrated to the Microsoft 365 admin center and is now called the Microsoft CSP Program. This means that all subscription and perpetual licenses can be accessed from the same platform. The same benefits and accessibility which comes with Volume Licensing is now available in the Microsoft CSP Program. No longer needing to keep track of the license keys manually or losing the keys once a machine has been lost, damaged, or stolen. Prior to volume licensing (now Microsoft CSP Program), all licenses purchased had to be upkept manually and Microsoft was not liable for any license keys which were unretrievable or if the client lost the license keys. The most common form of keeping track of the license keys bought in bulk was either a conventional spreadsheet or a KMS server which housed the keys for mass activation and distribution.

Microsoft Volume Licensing (now Microsoft CSP Program) has solved that issue. Now all keys are distributed and housed in an electronic vault. This electronic vault is called Microsoft 365 admin portal. The Microsoft 365 admin portal is accessible from any web browser to distribute the license keys. Within the Microsoft 365 admin portal, all clients are able to download the appropriate software for the licenses purchased, distribute and download the license keys, electronically retrieve license keys without physically touching the device, and share administrative roles within the Microsoft 365 admin portal.

The Microsoft 365 Admin portal houses the available perpetual licenses of the Microsoft product line which include Windows 10 Pro (Upgrade), Windows 10 Enterprise, Windows Server Standard, Windows Datacenter, SQL Server Standard, SQL Server Enterprise, Visio, Project, Visual Studio, Exchange Server, SharePoint Server, Windows Server Essentials, Windows User CALs, Windows Remote Desktop User CALs, and Windows SQL Server User CALs. Unlike Volume Licensing, there is never a need to purchase Software Assurance because any licenses purchased through CSP is always up-to-date.
