Sysprep /ˈsɪsprɛp/ is Microsoft's System Preparation Tool for Microsoft Windows operating system deployment.

History

Sysprep was originally introduced for use with

hardware abstraction layer

(HAL), in the "out of box" installation.

Purpose

Desktop deployment is typically performed via disk cloning utility. Sysprep can be used to prepare an operating system for disk cloning and restoration via a disk image.

Windows operating system installations include many unique elements per installation that need to be "generalized" before capturing and deploying a disk image to multiple computers. Some of these elements include:

Computer name^[1]

Security Identifier (SID)
Driver Cache

Sysprep seeks to solve these issues by allowing for the generation of new computer names, unique SIDs, and custom driver cache databases during the Sysprep process.

Administrators can use tools such as SetupMgr.exe (Windows XP) or the

answer files

that Sysprep will process on new computer deployments.

Alternatives to Sysprep

Sysinternals created a partial alternative to Sysprep, named NewSID, in 1997. However, after his own further analysis and research, Russinovich concluded that having duplicate SIDs is a non-issue and arranged NewSID's retirement.^[2]
