New servers running Windows Server 2003 R2 Datacenter Edition now have the license rights to run an unlimited number of virtualized Windows Server instances.
The change, which was effective Oct. 1, means that by licensing the server’s processors with Windows Server Datacenter Edition, users will be able to run Windows Server Standard Edition, Enterprise Edition, Datacenter Edition or a mix of the three editions without having to track the number of virtual machines or pay for additional Windows Server licenses.
Microsoft first announced the move at its annual Worldwide Partner Conference in Boston earlier this year.
