Need Help Fast... compressed drive will not uncompress totally...

I have a customer that compressed a drive then un compressed it.... Now some of his programs will not start...
I've tried the compact /u /s /i command o the c-drive but there are still alot of files compressed on the drive....
How can I un compress all files on the drive....
I am thinking that I could pull the drive and put it in another computer and use the compact command on the slave.... but will this cause other issues...

Also when I ran the compact command it did not go through the c:\program files directories.... this seems to be th bigest issue.... I have tried compact /u /s /i from the c:\program files \*.* directory but it had no effect....

You can see the color coded folder by opening Explorer, Tools, Folder Options, View, Show encrypted or compressed NTFS files in color.

The compact utility will do what you want, to change the attributes - but changing that does not actually decompress the files. They will be decompressed next time you open/edit/save them.

COMPACT [/C | /U] [/S[:dir]] [/A] [/I] [/F] [/Q] [filename [...]]

  /C        Compresses the specified files.  Directories will be marked
            so that files added afterward will be compressed.
  /U        Uncompresses the specified files.  Directories will be marked
            so that files added afterward will not be compressed.
  /S        Performs the specified operation on files in the given
            directory and all subdirectories.  Default "dir" is the
            current directory.
  /A        Displays files with the hidden or system attributes.  These
            files are omitted by default.
  /I        Continues performing the specified operation even after errors
            have occurred.  By default, COMPACT stops when an error is
  /F        Forces the compress operation on all specified files, even
            those which are already compressed.  Already-compressed files
            are skipped by default.
  /Q        Reports only the most essential information.
  filename  Specifies a pattern, file, or directory.

  Used without parameters, COMPACT displays the compression state of
  the current directory and any files it contains. You may use multiple
  filenames and wildcards.  You must put spaces between multiple
Which program did you use and what level of compression? Which file system?
