Explanation:
Imagex
ImageX is a command-line tool that enables original equipment manufacturers (OEMs) and corporations to capture, to modify, and to apply file-based disk images for rapid deployment. ImageX works with Windows image (.wim) files for copying to a network, or it can work with other technologies that use .wim images, such as Windows Setup, Windows Deployment Services (Windows DS), and the System Management Server (SMS) Operating System Feature Deployment Pack.

/append
Appends a volume image to an existing Windows image (.wim) file. Creates a single instance of the file, comparing it against the resources that already exist in the .wim file, so you do not capture the same file twice.

/mountrw
Mounts a .wim file from Windows XP with Service Pack 2 (SP2), Windows Server 2003 with Service Pack 1 (SP1), or Windows Vista with read/write permission to a specified directory.
Once the file is mounted, you can view and modify all the information contained in the directory.

Bcdedit
BCDEdit is a command-line tool for managing BCD stores. It can be used for a variety of purposes, including creating new stores, modifying existing stores, adding boot menu options, and so on. BCDEdit serves essentially the same purpose as Bootcfg.exe on earlier versions of Windows, but with two major improvements: BCDEdit exposes a wider range of boot options than Bootcfg.exe, and BCDEdit has improved scripting support.

NOT Windows SIM
Opens Windows images, creates answer files, and manages distribution shares and configuration sets.
NOTE: question specifies configuration data store, not configuration set.
