If you want to specify an alternative source file, in the Alternate source file path box, specify a fully qualified path of a shared folder that contains the contents of the \sources\sxs folder from the installation media. Or, specify a WIM file. To specify a WIM file as an alternative source file location, add the prefix WIM: to the path, and then add the index of the image that you want to use in the WIM file as a suffix. The following are examples of values that you can specify:
Path of a shared folder: \\server_name\share\Win8sxs
Path of a WIM file, in which 3 represents the index of the image in which the feature files are found: WIM: \\server_name\share\install.wim:3
If it is applicable to do this, select the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) check box.
Tap or click OK.
At an elevated command prompt, type the following command and then press Enter to apply the policy immediately: gpupdate /force
