What is Licensing?
A software product license grants you the legal right to run or access a software program. In other words, you don't actually own your software—you own the license to run that software.
A license agreement, such as Microsoft Software License Terms—also known as the End User License Agreement, or EULA—governs the use of licensed software. License agreements typically allow the software to run on a limited number of computers and allow copies to be made (though solely for backup purposes).
SAM Licensing
Software comes with its own type of media or documentation that serves as its proof of license. It is important that you retain the appropriate documentation for the software that your organization uses. If you purchase licenses through Microsoft Store, the "Account" page lets you view details for all of your orders and find the product keys for the software you have downloaded. You can also print individual receipts for record-keeping.

If you purchase through Microsoft Volume Licensing, you can view a “License Summary” that shows all of your licensed products, and a “Relationship Summary” that provides a comprehensive look at all your Volume Licensing agreements, Licensing IDs, and orders.

What Are Your Licensing Options?
Microsoft has several types of licensing programs designed to meet your organization's needs. For smaller organizations where fewer than five licenses are needed, Full Packaged Product (FPP) or Retail is probably right for you. If you’re looking to acquire new PCs along with your software, the OEM option might work better. For larger organizations that need more than five licenses, one of the many Volume licensing programs will suit your needs and save you money at the same time.

If your company's workstations are networked, you will use a network server, and the workstations on the network will access that server's software to perform certain functions such as file and print sharing. To legally access the server software, a Client Access License or CAL may be required. A CAL is not a software product—rather, it is a license that gives a user the right to access the services of the server.
Due to the technical nature of server products, Client Access Licenses can be a complicated area. For more information about CALs, visit the Microsoft Volume Licensing Web site.
