Windows Server virtualization licensing guidance document

There’s an updated (May 2025) Windows Server virtualization licensing document from Microsoft. There aren’t major changes from the previous version – the most significant one is the removal of all the (quite useful) diagrams. In addition, the original errors remain – the requirement for a customer to have a minimum of 16 Windows Server Core licences when licensing by virtual machine was removed in April 2023.

However, keep your Microsoft documentation stash complete by grabbing this document here: https://bit.ly/44doWLJ.

Flexible Virtualization Benefit Licensing Guide

There’s an updated (November 2022) Flexible Virtualization Benefit Licensing Guide. There are some diagrams added, and the requirement for multiple Windows Server Core licenses when a virtual core is mapped to more than one hardware thread, is removed.
