To use a network location to restore optional features and repair Windows images
You can use a mounted Windows image from a WIM file as a source to restore optional features and repair a corrupted operating system. For example, c:\test\mount\Windows. For more information about capturing a Windows image as a WIM file, see Capture Images of Hard Disk Partitions Using DISM.
You can use a running Windows installation as a source to restore optional features by sharing the c:\Windows folder on your network.
You can use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. For example, z:\sources\SxS.
You can use a Windows image (.wim) file on a network share as a source to restore optional features. You must specify the index of the Windows image in the .wim file that you want to use and you must use a Wim: prefix in the path to identify this file format. For example, to specify index 3 in a file named contoso.wim, type: Wim:\\network\images\contoso.wim:3.
