Windows 10: My CPU usage is at 100 when opening Task Manager

I tried scanning the PC with Malwarebytes, and a few other tools. The results came out clean. I finally installed a fresh new copy of windows on PC.

The CPU usage is still at 95-100% but goes down after a few seconds.


I tried using a few third party tools to monitor the CPU usage and it's normal.

CPU at 100% that goes away when opening Task Manager

Thanks for your answer @Jay#222. I understand that a computer is doing a lot in the background. In that case above, I was using Adobe Lightroom which is heavy on the CPU but I might get this when I'm just using Google Chrome googling things. Its weird to
me because upon opening the Task Manager, my CPU calms down when it might have been working hard for quite some time. My CPU might be working hard for 10 minutes and then upon opening Task Manager, it calms down. I'm sure if it listed the CPU usage prior to
opening the Task Manager, it would be 90%-100% usage all prior. Is it something like the Task Manager flushes processes and that's why it drop significantly? And I mean it drops to the point where the fan will calm down and my laptop will not lag much.

 

high cpu usage when task manager is open

i am having issues with cpu usage when i bring up the task manger it shows that cpu usage is 59% with the task manager app using up 30-40% cpu usage in the performance tab it show that my cpu usage is at 80% usage but when using other programs to check
my temps and cpu load etc is shows low 20s when gaming this can pin the cpu up at 100% in task manger

 

Task Manager High CPU Usage

I have the same problem myself with it only happens when I scroll through task manager and open and close it. I don't know this for sure but the reason this probably happens is that you may have a lot of processes running and task manager is using a lot
of the CPU to process the usage of each program.

What I have done is disable data that I don't need to see like network usage and GPU usage and it drops the CPU usage a bit. I have also enabled everything and scrolled up and down on it and task manager uses almost twice as much.

I would suggest disabling everything but CPU, disk, and RAM, (I would not suggest having GPU on because it is almost always at 99% unless you have FPS limits).
