vlmcsd is a replacement for Microsoft's KMS server.

It contains vlmcs, a KMS test client, mainly for debugging purposes, that also can "charge" a genuine KMS server designed to run on an always-on or often-on device, e.g. router, NAS Box, ...intended to help people who lost activation of their legally-owned licenses, e.g. due to a change of hardware (motherboard, CPU, ...)

vlmcsd is not a one-click activation or crack tool intended to activate illegal copies of software (Windows, Office, Project, Visio)
