Cpu usage high until i open task manager

My Acer laptop's fan has been running very loudly these past few weeks. When it gets too unbearable, I open Task Manager, only to find that my cpu usage lowers dramatically from 100% going as low to 13%.

Is this normal?

Hi,

Thank you for posting the query on Microsoft Community.

Restart the computer a few times and check for Windows Updates.

In the Search box on the taskbar, enter Windows Update, select Windows Update. On the Windows Update page, select Check for updates.

If the issue persists, then try Clean Boot and check.

This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. It starts Windows by using a minimal set of drivers and startup programs.
How to perform a Clean Boot in Windows:
http://support.microsoft.com/kb/929135


Note: After troubleshooting, refer to this section "How to reset the computer to start normally after clean boot troubleshooting" in the above link.

Try to run the following commands and check if it helps.

1.   Open command prompt. (Type cmd in Search or Press Windows Logo Key+X. Click on Command Prompt admin).

1.   Type the following 4 commands at the CMD prompt:

dism /online /cleanup-image /restorehealth

sfc /scannow

powershell

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

1.   Close the CMD window.

2.   Check to see if the issue is resolved. If not, restart the PC.

Hope this helps in resolving the issue. If the issue persists, do get back to us. We will be happy to assist you.

Hello,

I searched for this question due to the same issue with my HP laptop. I also had this issue with my Sony laptop. I have only had this issue with Windows 10, and it is downright suspicious behavior.

If I had asked anyone prior to Windows 10 about this issue, the immediate response would have been "Spyware," as whatever is causing the issue immediately conceals itself upon revelation.

I am an instructor in IT and hold multiple certifications. I want to know WHY this is happening, not how to fix it.

Your solution does solve the problem, but why is this a problem? Why do I have Microsoft Certified applications burning up my CPU, fan, and HDD, when my system has been fully updated? Is there a 'smart' program utilized to scan for system performance and resilience during optimum downtime?

Some further information: my computer only does this when it is idle for a while after a long period of use.

I would imagine that most users would not notice this if they use their computer for a while and walk away, but my job and hobbies involve me coming back after what seems just the right amount of time. 

I want to know this for educational purposes more so than anything else. I will be likely be adding CompTIA A+ classes to my roster soon.

Thank you,

-CS

Hi

It is simply an abuse of hardware for the sake of crypto-currency mining. When you are not aware your CPU is used to mine electronic coins such as Monero and such. 

Whom does it serve? Only God knows :)

Hello!

my problem still persist after doing what you said.

I've run every update available and run the commands you wrote in the post but still the CPU usage is very high until I open the task manager, then it reduces the CPU usage to normal values around 2-5% iddle.

Thanks in advance.
