WMI Provider Host constantly disrupting performance of my CPU, especially when music is playing.

Anonymous

Hello,

The WMI Provider Host always flares up to about 30% of CPU usage after about 10 minutes on. When it does, if I'm playing any music it slows the computer down so the music becomes jerky and distorted and the computer runs slowly. I don't have any 3rd party virus programs, and haven't installed many programs, so don't understand why it does this.

I have a Windows 8 Desktop machine and mostly use it for internet and playing music, so this is particularly annoying when it happens.

I am not technically minded, so does anyone have a simple solution for a technophobe?!

Hi,

It appears that you have an issue with High CPU usage at idle. However, in order to guide you in the right direction; I will need some more information. Please help me by answering the question mentioned below.

Did you make any changes to the computer prior to this issue?

In-order to fix the High CPU usage issue, refer the following methods.

Method 1:

Check if you can experience the issue in ‘Safe mode with networking’; if safe mode with networking works fine then set the computer to ‘Clean boot’ state to check for software conflicts.

Step 1:

Windows Start-up Settings (including safe mode).

Step 2:

Keep the computer in clean boot and check the issue status.

How to perform a clean boot to troubleshoot a problem in Windows Vista, Windows 7, or Windows 8.

Note: Please go through the section: How to reset the computer to start as usual after troubleshooting with clean boot of the Kb article to boot the computer in normal startup after fixing the issue.

Method 2:

I would also suggest you to run “System Maintenance” to diagnose and fix the issue. It finds and cleans up unused files and shortcuts, and performs maintenance tasks.

Follow these steps:

a. Press “Windows key + W” from keyboard.

b. Type “Troubleshooting” without quotes in the search box and hit enter

c. From “Troubleshooting” windows click “View all” option from the left panel.

d. In the list of options, click on “System maintenance”.

e. Click “Next” and follow the on-screen instructions.

Since I installed the huge Windows 8.1 update on Oct 14th, the system works fine for about an hour after restart.

Then it stalls, works again, stalls. When stalling, the application bar at the top goes "pale". I cannot enter anything during the pale periods, nor scroll the page.

The CPU usage is around 25%. However, it strikes me, that at the top of the task manager list is nearly ALWAYS: WMI Provider list.

It took me 10 minutes to just enter this text.

Would appreciate any advice which will allow me to lead a normal computing life again :)

Hi Thomas,

LogonUI.exe belongs to Windows and from the error message it appears that the file is corrupted. Here’s what you can do.

Running System File Checker [SFC] scan might help you to get rid of this error message at the startup. SFC scan replaces the corrupted system files with the original version of Windows files on the computer.

Use the System File Checker tool to repair missing or corrupted system files.

If the issue still persists, run the DISM tool and check if it helps.

Refer to “Run the DISM tool” section. Please ignore the thread title.
