Microsoft has released Windows Server Update Services (WSUS), formerly known as Software Update Service (SUS) & then later changed to Windows Update Services (WUS). For now its called Windows Server Update Services. WSUS enables administrators to quickly and reliably deploy critical updates to their Windows 2000-based servers as well as desktop computers running Windows 2000 Professional or Windows XP Professional.

In addition to WSUS, Microsoft also offers Microsoft Update and Systems Management Server (SMS) 2003. Microsoft Update is free and is geared towards home users. WSUS requires a Windows Server Client Access License (CAL) and is meant for small to medium-sized businesses.
