/audit
Restarts the computer into audit mode. Audit mode enables you to add additional drivers or applications to Windows. You can also test an installation of Windows before it is sent to an end user.
If an unattended Windows setup file is specified, the audit mode of Windows Setup runs the auditSystem and auditUser configuration passes.
/generalize
Prepares the Windows installation to be imaged. If this option is specified, all unique system information is removed from the Windows installation. The security ID (SID) resets, any system restore points are cleared, and event logs are deleted.
The next time the computer starts, the specialize configuration pass runs. A new security ID (SID) is created, and the clock for Windows activation resets, if the clock has not already been reset three times.
/oobe
Restarts the computer into Windows Welcome mode. Windows Welcome enables end users to customize their Windows operating system, create user accounts, name the computer, and other tasks. Any settings in the oobeSystem configuration pass in an answer file are processed immediately before Windows Welcome starts.
/reboot
Restarts the computer. Use this option to audit the computer and to verify that the first-run experience operates correctly.
/shutdown
Shuts down the computer after Sysprep completes.
/quiet
Runs Sysprep without displaying on-screen confirmation messages. Use this option if you automate Sysprep.
/quit
Closes Sysprep after running the specified commands.
/unattend:answerfile
Applies settings in an answer file to Windows during unattended installation.
answerfile
Specifies the path and file name of the answer file to use.
如：sysprep /oobe /generalize /shutdown
