You can use the "-FACTORY" switch to install additional drivers and applications at the stage after the reboot that follows Sysprep. Running Sysprep is normally the last thing you do whenpreparing a computer for delivery. When turned on, the computer simply displays Windows Mini–Setup.

By running Sysprep in Factory Mode, the system instead reboots in a network–enabled state without starting the Mini–Setup. In this state, Factory.exe processes an answer file named "Winbom.ini", which initiates the following actions:

- Copies drivers from a network source to the computer.

- Starts Plug and Play enumeration.

- Stages, installs, and uninstalls applications on the computer from source files located on either the computer or a network source.

- Adds user data.
