Microsoft Toolkit (MSTK), formerly known as Office 2010 Toolkit or EZ-Activator, is an executable program designed to activate Microsoft products. Version 2.5.1 specifically targets older to mid-generation versions of Windows and Office.
Microsoft Toolkit exploits this architecture by installing a localized KMS server directly onto the user's individual machine.

To circumvent this, the toolkit also installs an automatic renewal service (often called "AutoKMS") that runs silently in the background. When the 180-day period is nearing its end, this service reactivates the software for another 180 days, creating a loop that effectively makes the activation "perpetual" from the user's perspective.
