Windows 10 by default does a hybrid shutdown which is supposed to make it quicker to start back up.
To fully shutdown you can hold the Shift key down while clicking the shutdown button.
Side note. A Restart will do a full shutdown before starting back up.
The following command
systemctl restart auditd
Returns the following error on CentOS
Failed to restart auditd.service: Operation refused, unit auditd.service may be requested by dependency only (it is configured to refuse manual start/stop).
See system logs and 'systemctl status auditd.service' for details.
Work around is to use service for the restart
service auditd restart
