DISM Command For Using DVD As Repair Source

[stringjunky]

If I wanted to use the installation disk as the source for replacement files when I have corrupted files, instead of Windows Update, do I just replace the C; drive as the source with the drive letter of my DVD player in the following command; shown in red? The 'Limit Access' argument means not to use Windows Update I think.

Dism /Online /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows /LimitAccess
