Windows Server 2008, codenamed "Longhorn Server" (alternatives: "Windows Vista Server" or "Windows Server Vista"), is the seventh release of the Windows Server operating system produced by Microsoft as part of the Windows NT family of the operating systems. It was released to manufacturing on February 4, 2008, and generally to retail on February 27, 2008. Derived from Windows Vista, Windows Server 2008 is the successor of Windows Server 2003 and the predecessor to Windows Server 2008 R2. It removed support for processors without ACPI, and is the first version that includes Hyper-V.
It is the last version of Windows Server that supports 32-bit processors (IA-32).
As of July 2019, 60% of Windows servers were running Windows Server 2008. [11]
Microsoft had released Windows Vista to mixed reception, and their last Windows Server release was based on Windows XP. The operating system's working title was Windows Server Codename "Longhorn", but was later changed to Windows Server 2008 when Microsoft chairman Bill Gates announced it during his keynote address at WinHEC on May 16, 2007. [12]
Beta 1 was released on July 27, 2005; Beta 2 was announced and released on May 23, 2006, at WinHEC 2006 and Beta 3 was released publicly on April 25, 2007. [13] Release Candidate 0 was released to the general public on September 24, 2007 [14] and Release Candidate 1 was released to the general public on December 5, 2007. Windows Server 2008 was released to manufacturing on February 4, 2008, and officially launched on the 27th of that month. [15]
Windows Server 2008 is built from the same codebase as Windows Vista and thus it shares much of the same architecture and functionality. Since the codebase is common, Windows Server 2008 inherits most of the technical, security, management and administrative features new to Windows Vista such as the rewritten networking stack (native IPv6, native wireless, speed and security improvements); improved image-based installation, deployment and recovery; improved diagnostics, monitoring, event logging and reporting tools; new security features such as BitLocker and address space layout randomization (ASLR); the improved Windows Firewall with secure default configuration; .NET Framework 3.0 technologies, specifically Windows Communication Foundation, Microsoft Message Queuing and Windows Workflow Foundation; and the core kernel, memory and file system improvements. Processors and memory devices are modeled as Plug and Play devices to allow hot-plugging of these devices. This allows the system resources to be partitioned dynamically using dynamic hardware partitioning – each partition has its own memory, processor and I/O host bridge devices independent of other partitions. [16]
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.
A Server Core installation can be configured for several basic roles, including the domain controller (Active Directory Domain Services), Active Directory Lightweight Directory Services (formerly known as Active Directory Application Mode [17] ), DNS Server, DHCP server, file server, print server, Windows Media Server, Internet Information Services 7 web server and Hyper-V virtual server roles. Server Core can also be used to create a cluster with high availability using failover clustering or network load balancing.
Andrew Mason, a program manager on the Windows Server team, noted that a primary motivation for producing a Server Core variant of Windows Server 2008 was to reduce the attack surface of the operating system, and that about 70% of the security vulnerabilities in Microsoft Windows from the prior five years would not have affected Server Core. [18]
The Active Directory domain functionality that was retained from Windows Server 2003 was renamed to Active Directory Domain Services (ADDS). [19]
Windows Server 2008 offers high availability to services and applications through Failover Clustering. Most server features and roles can be kept running with little to no downtime.
In Windows Server 2008, the way clusters are qualified changed significantly with the introduction of the cluster validation wizard. [23] 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.
This feature is only available in Enterprise and Datacenter editions of Windows Server.
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. [27] 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. [28] 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.
Windows System Resource Manager (WSRM) is integrated into Windows Server 2008. It provides resource management and can be used to control the amount of resources a process or a user can use based on business priorities. Process Matching Criteria, which is defined by the name, type or owner of the process, enforces restrictions on the resource usage by a process that matches the criteria. CPU time, bandwidth that it can use, number of processors it can be run on, and allocated to a process can be restricted. Restrictions can be set to be imposed only on certain dates as well.
Server Manager is a new roles-based management tool for Windows Server 2008. [29] 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. [30]
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. [37] Editions of Windows Server 2008 include: [38]
The Microsoft Imagine program, known as DreamSpark at the time, used to provide verified students with the 32-bit variant of Windows Server 2008 Standard Edition, but the version has since then been removed. However, they still provide the R2 release.
The Server Core feature is available in the Web, Standard, Enterprise and Datacenter editions.
Windows Server 2008 Foundation Released on May 21, 2009. [42]

Windows Server 2008 shares most of its updates with Windows Vista, given that the operating systems share a codebase. A workaround using the Microsoft Update Catalog allowed the installation of updates for Windows Server 2008 on Windows Vista, [49] adding nearly 3 years of security updates to that operating system (Support for Windows Vista ended on April 11, 2017, [50] while support for Windows Server 2008 ended on January 14, 2020).
The RTM release of Windows Server 2008 already includes the updates and fixes of Windows Vista Service Pack 1.
Service Pack 2 was initially announced on October 24, 2008 [51] and released on May 26, 2009. Service Pack 2 added new features, such as Windows Search 4.0, support for Bluetooth 2.1, the ability to write to Blu-ray discs, and simpler Wi-Fi configuration. Windows Server 2008 specifically received the final release of Hyper-V 1.0, improved backwards compatibility with Terminal Server license keys and an approximate 10% reduction in power usage with this service pack. [52]
Windows Vista and Windows Server 2008 share the same service pack update binary. [53]
On October 27, 2009, Microsoft released the Platform Update for Windows Server 2008 and Windows Vista. It backports several APIs and libraries introduced in Windows Server 2008 R2 and Windows 7 to Windows Server 2008 and Windows Vista, including the Ribbon API, DirectX 11, the XPS library, the Windows Automation API and the Portable Device Platform. [54] A supplemental update was released in 2011 to provide improvements and bug fixes. [55]
Windows Server 2008 shipped with Internet Explorer 7, the same version that shipped with Windows Vista. The last supported version of Internet Explorer for Windows Server 2008 was Internet Explorer 9, released in 2011. Internet Explorer 9 was continually updated with cumulative monthly update rollups until support for Internet Explorer 9 on Windows Server 2008 ended on January 14, 2020. [56] IE9 continued to receive updates as long as the operating system was with Extended Security Updates until January 10, 2023 for non-Azure customers and January 9, 2024 for Azure customers respectively and January 2026 for Premium Assurance customers.
The latest supported version of the .NET Framework officially is version 4.6, released on October 15, 2015. [57]
In July 2017, Microsoft released an update to add TLS 1.1 and 1.2 support to Windows Server 2008, however it is disabled by default after installing the update. [58]
Starting in March 2019, Microsoft began transitioning to exclusively signing Windows updates with the SHA-2 algorithm. As a result of this Microsoft released several updates throughout 2019 to add SHA-2 signing support to Windows Server 2008. [59]
In June 2018, Microsoft announced that they would be moving Windows Server 2008 to a monthly update model beginning with updates released in September 2018 [60] – two years after Microsoft switched the rest of their supported operating systems to that model. [61]
With the new update model, instead of updates being released as they became available, only two update packages were released on the second Tuesday of every month until Windows Server 2008 reached its end of life – one package containing security and quality updates, and a smaller package that contained only the security updates. Users could choose which package they wanted to install each month. Later in the month, another package would be released which was a preview of the next month's security and quality update rollup.
Installing the preview rollup package released for Windows Server 2008 on March 19, 2019, or any later released rollup package, will update the operating system kernel's build number from version 6.0.6002 to 6.0.6003. This change was made so Microsoft could continue to service the operating system while avoiding "version-related issues". [2]
The last free security update rollup packages were released on January 14, 2020. [62]
A second release of Windows Server 2008 (codenamed: Windows Server 7) based on Windows 7, Windows Server 2008 R2, was released to manufacturing on July 22, 2009 [63] and became generally available on October 22, 2009. [64] 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. It is also the final version of Windows Server that supports IA-64-based processors.
A service pack for Windows 7 and Windows Server 2008 R2, formally designed Service Pack 1, was released in February 2011. [65]
Support for the RTM version of Windows Server 2008 ended on July 12, 2011, [4] and users can no longer receive further security updates for the operating system. As a component of Windows Vista, Windows Server 2008 with Service Pack 2 continued to be supported with security updates, lasting until January 14, 2020, the same respective end-of-life dates of its successor, Windows Server 2008 R2 and Windows 7.
Microsoft planned to end support for Windows Server 2008 on January 12, 2016. However, in order to give customers more time to migrate to newer Windows versions, particularly in developing or emerging markets, Microsoft decided to extend support to January 14, 2020. [5] [7] [6]
Windows Server 2008 was eligible for the paid Extended Security Updates (ESU) program. The program allowed volume license customers to purchase, in yearly installments, security updates for the operating system for three additional years, until January 10, 2023. The program was also included with Microsoft Azure purchases, and Azure customers received an extra year of support, until January 9, 2024. The licenses are paid for on a per-machine basis. If a user purchases an Extended Security Updates license in a later year of the program, they must pay for any previous years of Extended Security Updates as well. [5] [66]
Prior to the ESU program becoming available, Windows Server 2008 was eligible for the now discontinued, paid Premium Assurance program (an add-on to Microsoft Software Assurance) available to volume license customers. Microsoft will, however, honor the program for customers who purchased it between March 2017 and July 2018 (while it was available). The program provides an extra six years of security update support, until January 13, 2026. [9] [8] [10] [67] This will mark the final end of all security updates for the Windows NT 6.0 product line after 19 years, 2 months, and 5 days.
Paid extended updates are not available for Itanium customers. [68] [67]
Windows Server 2003, codenamed "Whistler Server", is the sixth version of the Windows Server operating system produced by Microsoft. It is part of the Windows NT family of operating systems and was released to manufacturing on March 28, 2003 and generally available on April 24, 2003. Windows Server 2003 is the successor to the Server editions of Windows 2000 and the predecessor to Windows Server 2008. An updated version, Windows Server 2003 R2, was released to manufacturing on December 6, 2005. Windows Server 2003 is based on Windows XP.
Virtual PC is a discontinued x86 emulator software for Microsoft Windows hosts and PowerPC-based Mac hosts. It was created by Connectix in 1997 and acquired by Microsoft in 2003, after which the program was renamed Microsoft Virtual PC. In July 2006, Microsoft released the Windows version free of charge. The Mac version was discontinued the same year following the Mac transition to Intel. In 2009, Microsoft released Windows Virtual PC, which is only compatible with Windows 7 hosts, and is the technical foundation for the latter's Windows XP Mode. Windows Virtual PC does not officially support MS-DOS or operating systems older than Windows XP Professional SP3 as guests. Virtual PC was discontinued in 2011 in favour of Hyper-V.
Windows 7 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009. It is the successor to Windows Vista, released nearly three years earlier. Windows 7's server counterpart, Windows Server 2008 R2, was released at the same time. It was succeeded by Windows 8 in October 2012.
Windows XP Professional x64 Edition is an edition of Microsoft's Windows XP operating system for x86-64 personal computers. It was released on April 25, 2005, alongside the x86-64 versions of Windows Server 2003. It is designed to use the expanded 64-bit memory address space provided by the x86-64 architecture.
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft Corporation which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software.
Windows Services for UNIX (SFU) is a discontinued software package produced by Microsoft which provided a Unix environment on Windows NT and some of its immediate successor operating-systems.
Shadow Copy is a technology included in Microsoft Windows that can create backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the Volume Shadow Copy service. A software VSS provider service is also included as part of Windows to be used by Windows applications. Shadow Copy technology requires either the Windows NTFS or ReFS filesystems in order to create and store shadow copies. Shadow Copies can be created on local and external volumes by any Windows component that uses this technology, such as when creating a scheduled Windows Backup or automatic System Restore point.
Windows Vista is a major release of the Windows NT operating system developed by Microsoft. It was the direct successor to Windows XP, released five years earlier, which was then the longest time span between successive releases of Microsoft Windows. It was released to manufacturing on November 8, 2006, and over the following two months, it was released in stages to business customers, original equipment manufacturers (OEMs), and retail channels. On January 30, 2007, it was released internationally and was made available for purchase and download from the Windows Marketplace; it is the first release of Windows to be made available through a digital distribution platform.
Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Originally developed by Connectix, it was acquired by Microsoft prior to release. Virtual PC is Microsoft's related desktop virtualization software package.
Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. It is included in Pro and Enterprise editions of Windows NT as an optional feature to be manually enabled. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks.
Windows Server 2008 R2, codenamed "Windows Server 7", is the eighth version of the Windows Server operating system produced by Microsoft and released as part of the Windows NT family of operating systems. It was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009, the same respective release dates of Windows 7. It is the successor to Windows Server 2008, which is derived from the Windows Vista codebase, released the previous year, and was succeeded by the Windows 8-based Windows Server 2012.
Windows XP, which is the next version of Windows NT after Windows 2000 and the successor to the consumer-oriented Windows Me, has been released in several editions since its original release in 2001.
Windows NT is a proprietary graphical operating system produced by Microsoft as part of its Windows product line, the first version of which, Windows NT 3.1, was released on July 27, 1993. Originally made for the workstation, office, and server markets, the Windows NT line was made available to consumers with the release of Windows XP in 2001. The underlying technology of Windows NT continues to exist to this day with incremental changes and improvements, with the latest version of Windows based on Windows NT being Windows 11 in 2021.
Microsoft Forefront Unified Access Gateway (UAG) is a discontinued software suite that provides secure remote access to corporate networks for remote employees and business partners. Its services include reverse proxy, virtual private network (VPN), DirectAccess and Remote Desktop Services. UAG was released in 2010, and is the successor for Microsoft Intelligent Application Gateway (IAG) which was released in 2007. UAG is part of the Microsoft Forefront offering. Microsoft discontinued the product in 2014, although the Web Application Proxy feature of Windows Server 2012 R2 and later offers some of its functionalities.
Microsoft started development on the .NET Framework in the late 1990s originally under the name of Next Generation Windows Services (NGWS). By late 2001 the first beta versions of .NET Framework 1.0 were released. The first version of .NET Framework was released on 13 February 2002, bringing managed code to Windows NT 4.0, 98, 2000, ME and XP.
Windows Server 2012, codenamed "Windows Server 8", is the ninth version of the Windows Server operating system by Microsoft, as part of the Windows NT family of operating systems. It is the server version of Windows based on Windows 8 and succeeds Windows Server 2008 R2, which is derived from the Windows 7 codebase, released nearly three years earlier. Two pre-release versions, a developer preview and a beta version, were released during development. The software was officially launched on September 4, 2012, which was the month before the release of Windows 8. It was succeeded by Windows Server 2012 R2 in 2013. Mainstream support for Windows Server 2012 ended on October 9, 2018, and extended support ended on October 10, 2023. Windows Server 2012 is eligible for the paid Extended Security Updates (ESU) program, which offers continued security updates until October 13, 2026.
Server Core is a minimalistic Microsoft Windows Server installation option, debuted in Windows Server 2008. Server Core provides a server environment with functionality scaled back to core server features, and because of limited features, it has reduced servicing and management requirements, attack surface, disk and memory usage. Andrew Mason, a program manager on the Windows Server team, noted that a primary motivation for producing a Server Core variant of Windows Server 2008 was to reduce the attack surface of the operating system, and that about 70% of the security vulnerabilities in Microsoft Windows from the prior five years would not have affected Server Core. Most notably, no Windows Explorer shell is installed. All configuration and maintenance is done entirely through command-line interface windows, or by connecting to the machine remotely using Microsoft Management Console (MMC), remote server administration tools, and PowerShell.
Windows Server 2012 R2, codenamed "Windows Server Blue", is the tenth version of the Windows Server operating system by Microsoft, as part of the Windows NT family of operating systems. It was unveiled on June 3, 2013, at TechEd North America, and released on October 18 of the same year. It is the successor to Windows Server 2012, and is based on the Windows 8.1 codebase. Windows Server 2012 R2 is the final version of Windows Server to use the "R2" suffix, which had been used since the release of Windows Server 2003 R2 in 2005.
Windows Server 2016 is the eleventh release of the Windows Server operating system developed by Microsoft as part of the Windows NT family of operating systems. It was developed alongside Windows 10 and is the successor to the Windows 8.1-based Windows Server 2012 R2. The first early preview version became available on October 1, 2014 together with the first technical preview of System Center. Windows Server 2016 was released on September 26, 2016 at Microsoft's Ignite conference and reached general availability on October 12, 2016.
The history of Microsoft SQL Server begins with the first Microsoft SQL Server database product – SQL Server v1.0, a 16-bit relational database for the OS/2 operating system, released in 1989.
