Take ownership of files or other objects  This security setting determines which users can take ownership of any securable object in the system, including Active Directory objects, files and folders, printers, registry keys, processes, and threads.  Caution  Assigning this user right can be a security risk. Since owners of objects have full control of them, only assign this user right to trusted users.  Default: Administrators.
