Windows 10: Wrong CPU usage readings in taskmgr

Symptoms: I've noticed a difference in CPU usage readings between taskmgr and other performance monitor apps. Taskmgr shows around 30~40% cpu usage while aida64 and Sysinternals Process Explorer shows 5~10% Gamebar shows around 1-2% lower but roughly the same during daily office working load messager apps, vscode and edge etc. Also Detail tab in taskmgr seems correct, the system idle process takes a little more than 90% for the most of the time which is expected.Possible cause:I've recently changed the whole PC from Lenovo m910t i7-7700 to m920t i5-9400 and I just move my os drive Sam

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.

 

Wrong CPU usage on Windows 11

I noticed that in MSI afterburner CPU usage is wrong. During the game it shows 17%, while in task manage it shows 100%. I tried other apps inlcuding Asus GPU tweak and Windows in built "Game bar" and all of them show wrong CPU usage. The only real usage shows Task manager. Anyone having this problem? How to fix this?

 

Windows Explorer high CPU Usage in Windows 10

Hi Andrew,

Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

From there, you should see what applications are running on high CPU usage. You can also
restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

• Click on the Start button and type Services.
• Scroll down the list and look for Windows Management Instrumentation.
• Right click on it and select Restart.

Should you have further questions, please let us know.
