## What it is
vlmcsd is a portable open-source KMS emulator written in C that replaces Microsoft's KMS server, bundled with a vlmcs test client. It runs on nearly any OS and CPU architecture, designed for always-on devices like routers or NAS boxes to help users re-activate legally-owned licenses.

## Use cases
- run a self-hosted KMS server on a router or NAS
- recover Windows or Office activation after hardware changes
- test and debug KMS servers with a client
- emulate a Microsoft KMS server on Linux or BSD
- activate legally-owned volume-licensed Microsoft products

## When to choose
- you own volume-licensed Microsoft products and lost activation due to hardware changes
- you need a lightweight, portable KMS server on an always-on device
- you want to test or charge a genuine KMS server

## When to avoid
- you want a one-click activation or crack tool for pirated software
- you need a licensed, officially supported KMS solution for production
- you require an actively developed project with a formal license

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: networking, security
- domain: windows, self-hosted, developer-tools
- platform: windows, bsd, cross-platform, cli
- tags: kms-emulator, license-activation, vlmcsd, c, portable, emulation, linux, macos, android, ios
