Windows Server 2008


 * Not to be confused with Windows Server 2008 R2.

Windows Server 2008 is the server counterpart of Windows Vista, which was released on 27 February 2008, a little over a year after its client counterpart. It replaces Windows Server 2003 and was replaced by Windows Server 2008 R2. It was the first version of Windows Server to include Hyper-V and also the last version of Windows Server to ship with the x86 architecture.

This is the first version of Windows Server that lacks support for systems without ACPI, as it will display a black screen with error messages when launched.
