Article Photo Licensing Details for Microsoft Products Learn about the differences between Microsoft retail products and volume licensing products available through the VLSC TechSoup - May 22, 2015 Learn about the differences between retail products and products available through the Volume Licensing Service Center. Microsoft products offered through TechSoup are volume license products. When you request a donated or discounted volume license product through TechSoup, you're actually requesting a license, not the product itself. Volume licenses are different from licenses for retail products primarily because they can apply to different versions of the software, can include Software Assurance benefits, and have different product terms.Licenses Can Apply to Earlier Versions, Multiple Languages, and Product FamiliesWhen you receive a Microsoft product through TechSoup, you can choose to download the current version of the software or the previous version. You can find out which version of the software is the current one on the Current Versions of Microsoft Software page. You can also download the software in any language that's available.For example, you might request 20 Windows Upgrade licenses through TechSoup. When you register with the VLSC, you can download the installation files for Windows 10 or Windows 8, in the 32-bit or 64-bit type, in English, French, Spanish, Chinese, or any other available language. You may, of course, only install a combined total of 20 operating systems.For more information on how to acquire installation software, see Microsoft Download Help.Software Assurance BenefitsSoftware Assurance is a collection of benefits included with Microsoft products requested through TechSoup. These benefits include free software upgrades, Office Multi-Language Packs, Office suites for use at home, e-learning courses, and more. See a full list of Software Assurance Benefits Included with Microsoft Products.Product TermsVolume Licensing products have slightly different terms from retail products.
