Managing a huge cluster environment has always been a hard task. We will introduce a system, which makes it possible to easily install, manage and update the worker nodes or the Windows machines in a computer room. We show how this task can be accomplished using only free tools. The system has the following capabilities:

• Installs a machine from scratch

• Uses PXE boot to perform the update

• Updates are executed automatically

• Handles versioning

• Uses wake on LAN to manage the machines

• Securely transmits the data required for updates
