The confirmation came from Steve Guggenheimer, Microsoft's original equipment manufacturer division corporate vice president, during a keynote speech at the Computex electronics exhibition in Taipei. Microsoft has said the server product was on schedule for release around the same time as Windows 7.
The release candidate for Windows Service 2008 R2 has been available since last month, when Microsoft also announced several new features.
Those included the ability for Hyper-V, Microsoft's server virtualisation software, to support 64 logical processors where it could previously only scale up to 32.
Another feature is the processor capacity mode, which allows for virtual machines to be moved to another physical server with a different CPU version. Before Hyper-V could only move virtual machines to servers with the same CPUs, which required administrators to buy more hardware.
The latest version also has a feature for classifying data in file servers by importance. The File Classification Infrastructure let administrators prioritise certain business data and back that data more often.
