答案原文
Windows Defender Service is using high CPU all the time. What can I do about this?.
This is exactly the solution that most of the users that arrive here
are looking for. There is an immediate drop in CPU usage by the
service in question.
For those that don’t understand I’ll outline it a bit better:
Open Windows Defender
Open the “Settings” tab
Select “Excluded Files and Locations”
Select “Browse”
Navigate to C:\Program Files\Windows Defender\MsMpEng.exe (Unless
Windows Defender is installed elsewhere for whatever reason)
Select “OK”
Select “Add”
Select “Save Changes”
The result should be immediate.
网页直接翻译过来
这 正是大多数到达这里的用户正在寻找的解决方案。有关服务的CPU使用率立即下降。
对于那些不了解的人，我会更好地概述一下：
打开Windows Defender
打开“设置”选项卡
选择“排除的文件和位置”
选择“浏览”
导航到C：\ Program Files \ Windows Defender
MsMpEng.exe（除非出于任何原因在其他位置安装了Windows Defender）
选择“确定”
选择“添加”
选择“保存更改”
结果应该是立即的。
嗯这样应该就行了
