Service Pack 1 Added the ability to slipstream a Service Pack into a Windows 2000 Installation Source, sitting either on a disk, or across a network. SP1 also included the High Encryption Pack. If slipstreamed, and the new SP1 Install is Booted from CD, Windows 2000 will install with High-Encryption enabled.
