A Windows Key Management Service (KMS) key is a specific type of product key used for volume activation of Microsoft Windows operating systems. It is designed for organizations that need to activate multiple computers or devices using a centralized activation method.
The KMS key is used to activate Windows installations on client computers that connect to a KMS server. When a client computer contacts the KMS server, it requests activation and receives the KMS key from the server. This key is then used to activate the Windows operating system on the client computer.
KMS keys are different from the standard retail or OEM product keys that are typically used for activating individual copies of Windows. KMS keys are provided to organizations through volume licensing programs and are intended for activation on multiple devices within the organization's network.
KMS activation has certain advantages for organizations, such as simplified activation management, centralized control, and automatic renewal of activations. However, it requires a minimum number of client computers (usually 25 or more) to activate a KMS host server and maintain the activation status.
It's important to note that KMS keys should be used only within the licensing terms and agreements provided by Microsoft. Unauthorized use or distribution of KMS keys is a violation of software licensing policies and can be considered software piracy.
Note: These keys are part of the public domain and are available directly from Microsoft. These require you to have a KMS server running within reach of the system you’re trying to activate. These can't be used to pirate software.
