DISM & SysPrep

Una de las ventajas de las últimas versiones de los Sistemas Operativos de Microsoft es la edición de las imágenes de instalación, podemos personalizar nuestra propia imagen WIM para realizar diferentes funciones y luego utilizarla desde un DVD o mediante WDS en un servidor de red y las funciones PXE.

Algunas de estas funciones pueden ser:

• Install.
• Boot.
• Capture.
• Discover.

Windows 7 introduce la herramienta de línea de comandos Deployment Image Servicing and Management Tool (DISM) para editar una imagen de Windows o para preparar una imagen de Windows PE, reemplaza al Administrador de paquetes (Pkgmgr.exe), PEimg y Intlcfg en Windows Vista e incluye nuevas características.
Lista de los comandos y parámetros que podéis necesitar, en Ingles.

Lista de las opciones de DISM para editar las imágenes

/mount-wim Mounts the WIM file to the specified directory so that it is available for servicing. The optional /readonly flag sets the mounted image with readonly permissions.

Example: dism /mount-wim /wimfile:C:\practice\myimages\ install.wim /index:1 /mountdir:C:\practice\offline/readonly

Flags

/wimfile:<path_to_image.wim>

/index:<image_index>

/name:<image_name>

/mountdir:<path_to_mount_directory>

/readonly

/commit-wim Applies the changes you have made to the mounted image. The image remains mounted until the /dismount option is used.

Example: dism /commit-wim /mountdir:C:\practice\offline

Flags

/mountdir:<path_to_mount_directory>

/unmount-wim Dismounts the WIM file and either commits or discards the changes that were made while the image was mounted.

Example: dism /unmount-wim /mountdir:C:\practice\offline /commit

Flags

/mountdir:<path_to_mount_directory>{/commit | /discard}

/remount-wim Recovers an orphaned WIM mount directory.

Example: dism /remount-wim /mountdir:<path_to_mount_directory>

Flags

/mountdir:<path_to_mount_directory>

/cleanup-wim Deletes all the resources associated with a mounted WIM image that has been abandoned. This command does not dismount currently mounted images, nor does it delete images that can be remounted.

Example: dism /cleanup-wim

/get-wiminfo Displays information about the images within the WIM. When used with the /index option, information about the specified image is displayed.

Example: dism /get-wimInfo /wimfile: C:\practice\offline\install.wim /index:1

Flags

/wimfile:<path_to_image.wim>

/index:<Image_index>

/name:<Image_name>

Muchas veces necesitaremos preparar el sistema antes de una captura de imagen, para ello utilizaremos el comando Sysprep

/audit Restarts the computer in Audit mode rather than Windows Welcome mode. Audit mode lets you add additional drivers or applications to Windows 7. You can also test an installation of Windows 7 and verify its integrity before it is sent to a user. If you specify an unattended Windows setup file, the Windows Setup. /audit mode runs the auditSystem and auditUser configuration passes.

/generalize Prepares the Windows installation to be imaged. If you specify this option, all unique system information is removed from the Windows installation. The SID is reset, system restore points are cleared, and event logs are deleted. The next time the computer starts, the specialize configuration pass runs. A new SID is created, and the clock for Windows activation resets (unless the clock has already been reset three times).

/oobe Restarts the computer in Windows Welcome mode. Windows Welcome enables users to customize their Windows 7 operating system, create user accounts, and name the computer. Any settings in the oobeSystem configuration pass in an answer file are processed immediately before Windows Welcome starts.

/reboot Restarts the computer. You can 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.You can use this option if you want to automate Sysprep.

/quit Closes Sysprep after the specified commands complete.

/unattend: answerfile Applies settings in an answer file to Windows during unattended installation. The variable answerfile specifies the path and file name of the answer file.
