chown:  Change the ownership of files or directories

Usage:  chown [-ADPrRtTh-] userid file1 [ file2 ... ]

   chown will change the ownership of NTFS files or directories
   to the specified user.  chown will not run under Windows 9x.

   The userid may be specified as either a simple name or as a
   machine\name pair.  (Warning:  specifying a name on another
   machine can take several seconds for network handshaking.)
   The userid is omitted when using the -R, -t or -T options.

   To use this command to take ownership for yourself, you must
   have this right:

      Take ownership of files or other objects

   If you would like to grant ownership to another userid, you
   must also have this right:

      Restore files and directories

   These rights can be granted via the User Manager.

Options:

   -A             Add an access control entry to any access
                  control lists, granting full access to the
                  new owner.
   -D             Default ACL, inheriting from the parent but
                  adding an ACE allowing full access to the
                  new owner.
   -P             Private.  Add an ACL to each file allowing
                  full access to the new owner but no access
                  to anyone else.
   -r             Recursive.  If any of the paths specified
                  is a directory, chown will recursively walk
                  through the entire directory tree, changing
                  the ownership of all the contents.
   -R             Remove any ACL.  The userid argument is
                  omitted.  (Warning:  a null ACL grants full
                  access to everyone and cannot be edited with
                  the Microsoft cacls command.)  The userid
                  argument is omitted.
   -t             Take.  Change the ownership to the same as
                  that of the current process.  If you are
                  running elevated as an Administrator, ownership
                  will be taken in the name of that group.
                  (This is so that Administrators can easily
                  share files.)  The userid argument is omitted.
   -T             Take ownership in your own name, even if you
                  running elevated as an Administrator.  The
                  userid argument is omitted.

   -h             Help.  (This screen.)
