1）Software Protection 与 Windows Defender是两个独立的服务。在Windows 服务中他们的描述分别为
Software Protection |
Enables the download, installation and enforcement of digital licenses for Windows and Windows applications. If the service is disabled, the operating system and licensed applications may run in a notification mode. It is strongly recommended that you not disable the Software Protection service. |
 |
Windows Defender Antivirus Service |
Helps protect users from malware and other potentially unwanted software |

3）实时保护部分的设定可以参考：https://docs.microsoft.com/en-us/windows/security/threat-protection/microsoft-defender-antivirus/configure-real-time-protection-microsoft-defender-antivirus#disable-real-time-protection-in-group-policy， 默认情况下，Real-time protection中的设置没有开启。
4）Scan设置，如设置在Scan期间最大占用CPU比例（默认为20%），定时扫描的时间(默认为Never)。
也可以通过Schedule Job来设置Scan的时间，同时也可以在Schedule Job中查看触发的条件：https://support.microsoft.com/zh-cn/help/4026132/windows-10-schedule-scan-microsoft-defender-antivirus
