Determine your licence requirements

Soft & Cloud Licence Configurator

Please note that you need licences to use Microsoft Windows Server.. Microsoft's standard licensing model is the Server CAL model. This means that, in order to comply with licensing requirements, you need both a licence to operate a server and access licences. You can choose between licensing by user (User CALs) and licensing by device (Device CALs).

To determine the licence requirements for Windows Server 2016, Windows Server 2019 or Windows Server 2022, the following four rules must be observed. All rules are taken into account in our licence configurator, so you can calculate your requirements yourself.

Rule No. 1: Each physical processor is counted as having at least eight cores.
Rule No. 2: Each physical server is counted as having at least 16 cores.
Rule No. 3: Taking into account rules 1 and 2, all physical and active cores in the server must be licensed so that a standard server has two virtualisation rights and a data centre server has unlimited virtualisation rights.
Rule No. 4: To obtain two additional VM rights with the Standard Edition, all physical active cores must be licensed again according to rules 1 and 2.
