Windows 10: Windows 10 taskhostw.exe at 100% CPU but only on performance monitor

Hello guys!I've recently been investigating my computer not running as fast as it should, and came across concerning information from Performance Monitor that taskhostw.exe was using near 100% cpu. This is consistent whenever i run a scan no matter what applications I have open at the same timeThe confusing thing however, is that when I check cpu usage on other tests task manager, resource monitor, process explorer it seems nothing is wrong.I'm worried that this could be a virus mining crypto or similar that somehow manages to fly under the radar. This is especially worrying because my cpu f

Windows 10 Task Manager shows 100% CPU but Performance Monitor Shows less than 2%

Hi

Today,I have updated my PC to Windows 10 from Windows 8.1 pro.

Everything is working fine except Task Manager in Windows 10. Task Manager always shows 100% CPU , which is incorrect as per the Performance Monitor application. I have verified CPU usage with other 3rd Party application as well, which all show CPU usage
as indicated by Performance Monitor. Someone please help me if there is a fix for this issue.

CPU:Intel Core i7 2600K @ 3.40GHz

RAM: 12GB

Motherboard:Intel Corporation DH67CL

GPU: NVIDIA GeForce GTX 550 Ti

 

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.

 

taskhostw.exe error in Performance Monitor

I've gone through all the steps to remove the potential taskhostw.exe malware and it still occurs in my Performance Monitor when I run a System Diagnosis check. It's still coming up as "Process taskhostw.exe [ProcessId: 2068] has a high CPU consumption of
99.3%".

Is there anything one may suggest to fix this?
