WIM is the abbreviation of English Microsoft Windows Imaging Format (WIM), which is a Windows file-based imaging format. The WIM image format is not the sector-based image format that is quite common today, it is file-based. Windows Vista uses this format for quick installation on new computers. WIM files store copies (called images) of one or more operating systems, such as Windows Vista or Windows PE. Maintaining your operating system is easy using WIM files because you can add and remove drivers, updates, and Windows components offline without booting the operating system. Maintaining Windows PE images using WIM files is very similar to maintaining Windows Vista images.

By using the file-based image format, WIM has the following benefits compared to other formats:

• WIM is a file-based image format,

• WIM image format is hardware agnostic, meaning you only need one image to address many different hardware configurations.

• The WIM image format also allows you to store multiple images in a single actual file. For example, Microsoft can ship multiple SKUs in a single WIM image file. You can store images with or without core applications in a single image file. Furthermore, you can mark one of the images as bootable, allowing you to boot your computer from the disk image contained in the WIM file.

• The WIM image format also enables compression and single instance, which can significantly reduce the size of the image file. Singleton is a technology that allows you to store multiple copies of a file using the space of one copy of the file. For example, if images 1, 2, and 3 all contain file A, then the singleton stores a single copy of file A and points images 1, 2, and 3 to that copy.

• The WIM image format allows you to maintain images offline. You can add or remove certain operating system components, patches, and drivers without creating a new image. For example, with Microsoft Windows XP it now takes you several hours to update an image, whereas with Windows Vista it only takes a few minutes. For example, to add a patch to a Windows XP image, you must boot the master image, add the patch, and then prepare the image again. For Windows Vista, you can maintain images offline.

• Unlike sector-based image formats, which require you to deploy the disk image to a partition that is greater than or equal to the size of the source disk, the WIM image format allows you to mount a disk image on a partition of any size.

• Windows Vista provides an API for the WIM image format called WIMGAPI that developers can use to work with WIM image files.

• The WIM image format allows for non-destructive deployment. This means that you can keep data on the volume to which you applied the image, because the application of the image does not clear the existing contents of the disk.
