def get_pending_file_rename():
    '''
    Determine whether there are pending file rename operations that require a
    reboot.

    .. versionadded:: 2016.11.0

    Returns:
        bool: ``True`` if there are pending file rename operations, otherwise
        ``False``

    CLI Example:

    .. code-block:: bash

        salt '*' system.get_pending_file_rename
    '''
    vnames = ('PendingFileRenameOperations', 'PendingFileRenameOperations2')
    key = r'SYSTEM\CurrentControlSet\Control\Session Manager'

    # If any of the value names exist and have value data set,
    # then a reboot is pending.

    for vname in vnames:
        reg_ret = __utils__['reg.read_value']('HKLM', key, vname)

        if reg_ret['success']:
            log.debug('Found key: %s', key)

            if reg_ret['vdata'] and (reg_ret['vdata'] != '(value not set)'):
                return True
        else:
            log.debug('Unable to access key: %s', key)
    return False
