Windows 10: 100% CPU - How and Why?

Hello Guys,

I thought I was fairly tech savy. Today I am asking myself, how do you not know how to diagnose this?



Last night I updated to Windows 10, edition 2004.

I noticed my turbo fan kicked in on my laptop, usually meaning the CPU usage is running high and or hot. So I powered her down. Powered on. It then asked me to restart to apply further updates. Now I seem to be constantly running at 100% CPU usage since then.

Task manager is telling me the CPU usage is stuck on 100%, no matter what.

Picture of Taskmanager: https://ibb.co/W3g3cvD



I have 4 main processes' that are labeled as "Very High" in the power usage column. They seem to bounce in and out of that status.

I am running a MSI gaming laptop (i7 770HQ, 16GB DDR4, 1050GTX, plenty of storage left on both SSD's) and wouldn't expect 100% usage while idling like this. Windows update is not currently running and shows me as up to date.



Has anyone else experienced this since the rollout? I feel like as they are windows processors that are maxing out, that it could be my hardware?

TIA!!

EDIT: Checked MSI's version of task manager. Who do I believe here!

100% CPU Usage after Windows 10 upgrade

Hello Aaron,

Thank you for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.

Most of the time, computers only use a small fraction of their CPU power. In fact, many computers use less than 5% of their CPU most of the time. When you open an application, play a video game, or encode media file, the CPU usage will rise or spike temporarily.
Once the CPU intensive process completes, the CPU usage should once again drop down to lower level. Most applications will not use up more than 50% of your CPU for an extended period of time. However, some programs and system processes can use up a large amount
of CPU without you even knowing it. This may happen if a program gets stuck in an infinite loop or encounters an unexpected error.

I suggest you to perform Safe mode and Clean boot procedures on the PC by following the steps below.

Step 1: I suggest you to boot your PC in Safe mode by following the steps from the link below and check if the issue is resolved.

Safe mode is a diagnostic mode that starts your computer with limited drivers necessary to run Windows. The words
Safe Mode appear at the corners of your monitor to identify which Windows mode you are using.

Expand the options to boot into Safe Mode:

Reboot the PC to exit from Safe mode.

To know more about Safe mode, following is an article on
Windows Startup Settings (including safe mode) (Applies to Windows 10 also):

http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-safe-mode

Step 2: If the issue persists, perform Clean boot on your PC by following the steps from the link below and check if the issue is resolved.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue.

I suggest you to perform clean boot by following the steps from the link below and check if the issue is resolved.

You can open the system configuration window in Windows 10:

a. Using run command.

• • Press Windows Key + R keys on the Keyboard.
  • Type msconfig.msc and press Enter.

b. Using Cortana.

• • Press Windows icon key on the keyboard and type msconfig.
    
  • Select the top most search result.
    

Follow the steps from 3 under How to perform a clean boot
for Windows 8.1 and Windows 8 from the link below (The steps for clean boot suggested in the link below for
Windows 8/8.1 is applicable for Windows 10 as well):

https://support.microsoft.com/en-us/kb/929135

Disclaimer: Start the computer in normal mode refer the section,
How to reset the computer to start normally after clean boot troubleshooting
from the link above.

Write to us with the status of the issue on the same post for further assistance. Your reply is most important for us to ensure we assist you accordingly.

Thank you.

 

INCORRECT CPU FREQUENCY READING

Hello Muhammad,

CPU usage depends on the applications that are open to your device. To isolate the problem, we suggest that you answer the following questions:

• Can you include a screenshot of the CPU reading?
• Have you tried performing a
  clean boot to eliminate software conflicts?
• What troubleshooting steps have you done so far?

Looking forward to your response.
