Windows 7 Imaging & Answer Files

Imaging & Answer FilesWindows 7 is spread in wim files which use the Windows Imaging files format. You can do wim file settings for the following.

Windows 7 Imaging files
Windows Imaging files are file-based image format that lets you store multiple images in one file. If you don’t want to deploy paging files using the image then you can perform partial volume captures by excluding files.

By using a compressed file format and single-instance storage techniques, this format reduces files sizes. To reduce the size of image files that contain multiple images, this image file contains one physical copy of a file for each instance of it in the image file.

To update files in images they contain, you can mount .wim files as folders.

You can apply an image to the destination computer's hard disk using Windows 7 Imaging file. Because .wim files don’t require the destination computer's hard disk to be the larger size or same than the source hard disk, so, you can also apply an image to different-sized destination drives.

You can use CD-ROMs to distribute large .wim files with Windows Imaging files.

You can start Windows PE from a .wim file because Windows PE .wim files are bootable. In fact, Windows Deployment Services and Windows Setup start Windows PE from the .wim file 'Boot.wim', which you can customize by adding items such as device drivers and scripts.

Windows 7 Answer Files:
It is a XML-based file that contains settings to use during a Windows 7 installation. An answer file can fully automate all or part of the installation process. In this file, you confer settings such as the product key to apply, how to partition disks and the location of the Windows 7 image to install. You can also change settings of the Windows 7 installation, changing display settings, adding user accounts and updating Windows Internet Explorer favorites. These files are commonly referred as Unattend.xml.

Wim file
To create an answer file and combine it with a particular Windows 7 image, you use Windows SIM. This combination lets you to validate the settings in the answer files against the settings available in the Windows 7 image. Windows setup ignores settings in the answer files for features that do not exist in the Windows image because you can use any answer file to install any Windows 7 image.

The answer file feature section contains all the feature settings that Windows Setup applies. Windows PE, offline Servicing, generalize, specialize, auditSystem, auditUser, and oobeSystem are the different configuration passes into which Answer files organize features. Each configuration pass describes a different installation phase and not all passes run during the normal Windows 7 setup process. You can also apply settings during one or more passes. You can choose the pass in which to apply the setting if a setting is available in more than one configuration pass.
