A large group of Microsoft customers are OEMs that assemble and sell computers such as desktops, laptops, tablets, and mobile devices. For devices sold by these OEMs, Windows license data is stored in the computer`s BIOS in an area called « ACPI_SLIC » so that KMS can detect usage of previous Microsoft products even when the storage device is removed or deleted.  For Windows Vista and Windows 7, SLIC data complements each other. The device always comes with a volume license product key that the user needs when reinstalling Windows. However, starting with Windows 8, everything needed to authorize the device is stored with SLIC data. The purpose of this article was not to confuse or discourage the reader from pursuing a volume licensing agreement with Microsoft®. As mentioned earlier, you may not have a choice, but it`s important to know what you`re getting into. There are a number of third-party resources available to help you through the process. The Microsoft® Volume Licensing home page www.Microsoft.com/licensing/ provides a number of documents, manuals, and program overviews. The Volume Licensing Reference Guide, product list, product usage rights and product usage rights are particularly useful. Traditionally, a volume license (ADA) key, which could be made available to all instances of the licensed computer program, was involved in volume licensing.
With the popularity of software-as-a-service practices, volume licensing customers only provide their software with credentials that belong to an online user account used for other aspects of services and delivery. Users who use these keys receive an error message when they install the latest service pack, and these users are prompted to purchase a legitimate license and change their product key.  The unique ESP Trustbrand Cloud portal gives you simplified management that allows you to control your license usage, view current and expected Azure usage, and access detailed billing information. The simple fact that Microsoft® has so many products and sells them in virtually every country also adds to the complexity of the program. As mentioned earlier, regional subsidiaries cater to local markets and economies. In addition, there are many VL agreements with customers with a multinational presence, all governed by the same agreement. Microsoft`® wouldn`t be able to compete in many regions if they weren`t sensitive to local markets. Volume licenses are not always transferable. For example, only certain types of Microsoft volume licenses can be transferred, provided that a formal transfer process is completed and allows Microsoft to register the new owner. A very small number of software providers specialize in brokering such transfers to enable the sale of volume licenses and keys. .
