How to fix high CPU usage?

CPU usage is more inclined to be an issue within your personal computer rather than an application.

If an application is using too much CPU, try updating your drivers.

Drivers are programs that control particular devices connected to your motherboard.

Updating your drivers may eliminate compatibility issues or bugs that cause increased CPU usage.

How to do this?

  • Open the Start menu
  • Click "Settings".
  • Click "Updates & Security"
  • Click “Check for Updates” button which will update critical drivers.

There can be many factors causing a high CPU usage within your computer.

If the above update has not resolved your issue, here are a few steps to do in attempt to resolve this issue:

(1) Restarting WMI (Windows Management Instrumentation)

Manually restart the WMI (Windows Management Instrumentation) service. Please follow these steps in order to restart this service:

  1. Press Windows key + S, input Services, and press Enter.

  2. In the window that opens, look for Windows Management Instrumentation.

  3. Right-click it, then select Restart. You can also stop the service entirely, if you desire, or simply restart your computer.

(2) Identify Persistent WMI Provider Host Issues Using the Event Viewer

If the issue keeps returning, use the Windows Event Viewer to identify its cause. It could be another system process that keeps the WMI provider host busy, thereby causing high CPU usage.

  • In Windows 10 and 8, right-click the Start button and select Event Viewer.

  • In Windows 7, use the Start menu to find and launch Eventvwr.msc.

Inside the Event Viewer app, go to Applications and Service Logs > Microsoft > Windows > WMI-Activity > Operational.

Now scroll through the list of operational events and find recent Error entries.

For each Error, identify the ClientProcessId. Note that every time you restart a process, its ID will change, hence there's no point in checking older errors.

If you suspect that one of these processes is causing the high CPU usage, you can use its ID to find it in the Task Manager and identify the faulty process.

Open the Task Manager (press Control + Shift + ESC), switch to the Services tab, and sort all running services by PID, i.e., their process ID. If the guilty process is still running, you'll be able to identify it and investigate further.

Right-click the process and select Open File Location to review the software it belongs to. Updating or uninstalling the respective program may fix the WMI Provider Host's high CPU usage.

(3) Worm, Virus or Malware

There is a possibility that the service could be a worm or virus. You should see only one version of the process at any given time, and the process should stop if you halt it through the Services window. If you see two versions of it, or the process will not stop, run a virus scan immediately.

Malware can cause high CPU usage, too. A system that's infected may run processes in the background, and it may attempt to spread itself by sending malware to others via your email, your network, or other sources. All of this requires processing power, which can translate to poor performance.

If you don't have an anti-virus, download a free malware application and run it. In fact, you may want to try several anti-malware tools because malware that's already installed has the advantage; it may be able to hide from any single anti-virus app.

(4) Background Processes

A background process is a program that's running on your PC, even though it's not open in a window. A typical computer will have many background processes running simultaneously, as Windows itself requires some to run. But as you install programs over the years, you may collect more and more and eventually overwhelm your PC.

Press Windows key + X, then select Task Manager from the list. The Processes tab will appear by default, displaying not only overall CPU usage but also the usage of each app.

You should do this while no other programs are open to prevent confusion. Note the processes that appear to use at least 10% of your processor's capability regularly.

In Windows 10, head over to the Startup tab within the Task Manager.

In Windows 7, exit Task Manager and open msconfig.exe via Windows Search or the Run dialog (Windows key + R). In the System Configuration window, head to the Startup tab.

Now find startup items correlated with the items that you noted. Uncheck them, click okay, and then restart your PC. This will stop those programs from launching at boot.

The above are some methods that could improve your CPU usage.

They are not a guarantee fix and if not resolved we suggest you take your PC to a technician/repair centre.
