High CPU usage on Dell Inspiron 5570

It is in November 2019. There is a laptop, Dell Inspiron 5570. It is my mother in law’s laptop. Recently she found it is so slow and ask my help.

I connected this laptop through Teamviewer. I checked the CPU usage and found it is so high and the temperature is also high.

It is above 90 degrees.  The CPU usage is 100%. The top two are Intel PROSet/Wireless Event log service and Intel PROSet/Wireless Zero Configure Service.

 

 

 

The Windows 10 was upgraded to the latest one. build 1909.

I have to check the problem on Google and Dell community.

Actually I found the answer.

Disable Trackback sitewide

During the past 6 months, all trackbacks are spams. To save the resource of my server, I disable the trackback service sitewide.
I hope to see the CPU and Memory usage drop in the future.
There are still some problem of MovableType on Dreamhost.
Dreamhost is good. I use it for many small sites. But right now, I fell it is more restrict on memory usage. Any time I publish one post, 500 error comes. If rebuild site, situation worse.
I will keep watch it and see if it is getting better. Or I may transfer to VPS.
