   Windows updates/hotfixes files update the system files and place a backup in   
   the "x:\WINDOWS\$hf_mig$" folder.   
      
   The backup files are still required by the Windows internal file checker for   
   file restoration purposes in case the ones in the "x:\WINDOWS\SYSTEM32" and   
   "x:\WINDOWS\system32\dllcache\" are deleted or improperly updated to an   
   older version.   
      
   Since those updated files aren't included in the original Windows CD-ROM,   
   deleting the backup files would mean preventing the deleted/modified system   
   files from being restored to the recent version ever installed. Thus if the   
   backup is not found, the only way to restore the system file is by restoring   
   them from the CD-ROM, which aren't the recent versions.
