WSUS originated as Software Update Services (SUS), which delivered only operating system hot fixes and patches. WSUS builds on SUS by expanding the range of software it can update. The WSUS infrastructure allows automatic downloads of hotfixes, updates, service packs, device drivers and feature packs to clients in an organization from a central server(s), instead of using the public Microsoft Windows Update website. This saves bandwidth, time and disk space, as the individual computers in a network do not have to connect to an external server themselves, but connect to a local central server. It also increases administrators' control and allows clients to obtain updates in environments that do not have internet access
WSUS is the successor to Software Update Services (SUS).
Windows Server Update Services (WSUS), also called Windows Update Services (WUS), is a free add-on for managing patches and updates to the Microsoft Windows XP, Windows Server 2000, and Windows Server 2003 operating systems.
Aimed mainly at small and medium-sized businesses (SMB), WSUS is intermediate between the simpler Windows Update for individual computer users and the more robust Systems Management Server (SMS) for large enterprises.
WSUS features include:
• The incorporation of bandwidth management for optimum use of network resources
• Automatic download of updates by category
• The ability to target updates to specific computers or sets of computers
• Enhanced reporting capabilities
• Multiple language support.
Administrators can use WSUS with Active Directory Group Policy for client-side configuration of the Automatic Updates client, ensuring that end-users can't disable or circumvent corporate update policies. WSUS does not require the use of Active Directory; client configuration can also be applied by local group policy or by modifying the Windows registry.
Microsoft has made WSUS available on their web site as a free download. Microsoft also plans on including WSUS with Windows Server 2008, as an out-of-band component.
Customers are not able to use WSUS on their own as an external update system albeit since it is now part of the OS, this seems like an unlikely legal precedent.
