Configuration Pass	Description
windowsPE	Configures Windows PE options and basic Windows Setup options. These options can include setting the product key and configuring a disk. If you require drivers for Windows PE to access the local hard disk drive or a network, use this configuration pass to add drivers to the Windows PE driver store and to reflect boot-critical drivers required by Windows PE.
offlineServicing	Applies updates to a Windows image. Also applies packages, including software fixes, language packs, and other security updates. During this pass, you can add drivers to a Windows image before that image is installed and processes out-of-box device drivers during Windows Setup.
specialize	Creates and applies system-specific information. For example, you can configure network settings, international settings, and domain information.
generalize	Enables you to minimally configure the sysprep /generalize command, as well as configure other Windows settings that must persist on your reference image. The sysprep /generalize command removes system-specific information. For example, the unique security ID (SID) and other hardware-specific settings are removed from the image. The generalize pass runs only if you run the sysprep /generalize command.
auditSystem	Processes unattended Setup settings while Windows is running in system context, before a user logs onto the computer in Audit mode. The auditSystem pass runs only if you boot to Audit mode.
auditUser	Processes unattended Setup settings after a user logs onto the computer in Audit mode. The auditUser pass runs only if you boot to Audit mode.
oobeSystem	Applies settings to Windows before Windows Welcome starts.
