A large group of Microsoft customers are OEMs that assemble and sell computers such as desktops, laptops, tablets and mobile devices. On devices sold by these OEMs, Windows license data is stored in the computer`s BIOS in an area called “ACPI_SLIC,” allowing KMS to detect the use of previous Microsoft products, even if the storage device is removed or removed.  For Windows Vista and Windows 7, SLIC data is complementary; A volume license product key always comes with the device the user needs in the event of Windows reset. However, from Windows 8, everything that is needed for device authorization is stored with SLIC data. Traditionally, a product key comes with computer programs. It acts as a password: the old computer programs ask the user to prove their right; In response, the user provides this key. However, this key can only be used once, i.e. on a computer. However, a volume license key (RK) can be used on multiple computers. Creditors can take additional steps to ensure that the key to their products is only used in the intended number. These efforts are called product activation. There is an unofficial KMS server emulator that activates Windows or Office, even if the software has not been licensed or paid for, whether or not 25 or more computers are on the network, regardless of whether or not an earlier version of Windows has been installed.  There is also a program that sends KMS queries to a legitimate KMS server to make the server think there are 25 or more computers on the network.
Microsoft considers both exploits to be a violation of the terms and conditions of sale.  Traditionally, a volume licensing key (RK) that could be made available to all instances of the licensed computer program participated in the granting of a volume license. With the popularity of the software as service practices, volume license customers only provide their software with credentials that are part of an online user account, which is used for other aspects of services and provision. Microsoft Product has also been repeatedly criticized for violating patent law. In 2006, Microsoft was ordered to pay $142 million to z4 Technologies for violating a product activation patent, while Microsoft was ordered in 2009 to pay Uniloc $388 million for patent infringement in Windows XP, Office XP and Windows Server in 2003.

Users who use these keys receive an error message when they install the latest Service Pack, and these users are asked to obtain a legitimate license and change their product key.  Please keep in mind that the terms of your volume license agreement and the rights to use the products documented in this agreement govern your use of Microsoft-licensed products. While we have made it difficult to make it easier for you to access product usage rights and understand the rights to use products by this online tool, your use of this site should not replace reading and understanding your volume licensing agreement. We will endeavour to ensure that the content of this site complies with the documentation of the current volume license, but in the event of conflicting content, you should refer to the terms of your agreement. Microsoft has blocked several volume license keys that have been misused in services packs, starting with Windows XP Service Pack 1. Microsoft has even developed a new key verification engine for Windows XP Service Pack 2, capable of detecting illegal keys, even those that had never been used before. Several security advisers condemned Microsoft`s move and said it was irresponsible to remove a large installation base of various security vulnerabilities, as this uncorrected installation base can be
