What that article is saying is that you need to replace any dll files that are shown in the file. and giving you the instructions to be followed in the Administrator CMD prompt that you've used before, that will enable these files, which are normally protected, to be replaced.
as you have to source these files to replace the corrupt ones the easiest method would be a working copy of vista of the same type (Home, Ultimate with or without SP1 etc) if you have access to another machine.
If you cannot do this this link may help you find the files you need. DLL-files.com - Download all your missing dll-files.
Unfortunately, if you have a lot of files this will be a rather involved process, and with a lot of files it may be easier to perform a repair install. Repair Install For Vista
Hope this explains things
