Windows Server 2008 includes a variation of installation called Server Core. Server Core is a significantly scaled-back installation where no Windows Explorer shell is installed. It also lacks Internet Explorer, and many other non-essential features. All configuration and maintenance is done entirely through command-line interface windows, or by connecting to the machine remotely using Microsoft Management Console (MMC). Notepad and some Control Panel applets, such as Regional Settings, are available.

In Windows Server 2008, the way clusters are qualified changed significantly with the introduction of the cluster validation wizard.[19] The cluster validation wizard is a feature that is integrated into failover clustering in Windows Server 2008. With the cluster validation wizard, an administrator can run a set of focused tests on a collection of servers that are intended to use as nodes in a cluster. This cluster validation process tests the underlying hardware and software directly, and individually, to obtain an accurate assessment of how well failover clustering can be supported on a given configuration.
Hyper-V is hypervisor-based virtualization software, forming a core part of Microsoft's virtualization strategy. It virtualizes servers on an operating system's kernel layer. It can be thought of as partitioning a single physical server into multiple small computational partitions. Hyper-V includes the ability to act as a Xen virtualization hypervisor host allowing Xen-enabled guest operating systems to run virtualized.[23] A beta version of Hyper-V shipped with certain x86-64 editions of Windows Server 2008, prior to Microsoft's release of the final version of Hyper-V on 26 June 2008 as a free download. Also, a standalone variant of Hyper-V exists; this variant supports only x86-64 architecture.[24] While the IA-32 editions of Windows Server 2008 cannot run or install Hyper-V, they can run the MMC snap-in for managing Hyper-V.
Server Manager is a new roles-based management tool for Windows Server 2008.[25] It is a combination of Manage Your Server and Security Configuration Wizard from Windows Server 2003. Server Manager is an improvement of the Configure my server dialog that launches by default on Windows Server 2003 machines. However, rather than serve only as a starting point to configuring new roles, Server Manager gathers together all of the operations users would want to conduct on the server, such as, getting a remote deployment method set up, adding more server roles etc., and provides a consolidated, portal-like view about the status of each role.[26]
Most editions of Windows Server 2008 are available in x86-64 and IA-32 variants. These editions come in two DVDs: One for installing the IA-32 variant and the other for x64. Windows Server 2008 for Itanium-based Systems supports IA-64 processors. The IA-64 variant is optimized for high-workload scenarios like database servers and Line of Business (LOB) applications. As such, it is not optimized for use as a file server or media server. Windows Server 2008 is the last 32-bit Windows server operating system.[33]Editions of Windows Server 2008 include:[34]
A second release of Windows Server 2008 based on Windows 7, Windows Server 2008 R2, was released to manufacturing on July 22, 2009[60] and became generally available on October 22, 2009.[61] New features added in Windows Server 2008 R2 include new virtualization features, new Active Directory features, Internet Information Services 7.5 and support for up to 256 logical processors. It is the first server operating system by Microsoft to exclusively support 64-bit processors, while consumer-oriented versions of Windows maintained 32-bit support until Windows 11 in 2021.
My Dell server came preinstalled with 2008 R2 Standard. I upgraded to Enterprise to take advantage of more than 32GB RAM. This server is purely for dev and testing, so I want to use my MSDN product key for the upgrade.
