How to troubleshoot High CPU Usage for Windows

 High CPU usage can be characterized by slow cursor speed and applications that lag or stop responding. The workstation may also overheat as it tries to complete tasks. These are signs that you should look at your processor when diagnosing a computer may be sending automated Windows 7 error.

It’s easy to check the bottom of a Windows laptop or desktop and determine if the problem can be fixed or if the CPU needs to be replaced.

What does CPU Time Represent?

The Central Processing Unit (CPU) or processor is at the heart of every computing device. It is responsible for processing the user’s instructions. The CPU of a device can only handle so many tasks or processes at once. If the CPU is stressed, performance starts to suffer. CPU time, or processing time, is the time the CPU spends processing instructions received from the OS or application. If the count is high, it means that the system is overloaded or busy.

Too many apps can cause high physical memory usage. However, it can also be the result of a bug in a process that would otherwise be far less resource-intensive. There can be many reasons for slow processing, and some will be more difficult than others. However, in most cases, it is easy to reduce CPU usage by pressing Control+Shift+ESC.

How can I monitor CPU usage in Windows?

To find out how much CPU your computer uses, open Windows Task Manager (Control+Shift+ESC) and click on the Performance tab. The Processes tab takes an in-depth look at the problem and lists the processes that are using the most CPU and RAM. This is important for finding ways to reduce CPU usage. You can either eliminate unnecessary processes or fix the root cause if they are not.

How can I reduce high CPU usage?

If the problem is not being attributed to a particular app, then it could be due to a bug in a less obvious process. There are many reasons why your computer may have problems. Let’s look at some of the most common and show you how to fix them.

1- WMI Provider Host Process

The WMI Provider Host is an important part of Windows that runs in the background. It usually appears under Service Host Windows Management Instrumentation. This process monitors multiple systems in a network and detects whether their CPU usage exceeds a certain percentage point. If it does, your system may be suffering from a serious bug. This is the fastest way to solve the problem. Stop the process, and then start it again. Windows Search will search for Services.MSC. Once you find Windows Management Instrumentation, click on it and then select Restart.

This should restart the service. However, if you wish, you can also restart your computer. If that fails, it may be because the WMI provider host is dealing with another process. Open Windows Event Viewer. Select Application and Service Logs, then Microsoft and finally Windows, WMI Activity and Operational. You can search for errors and track down the Client Process ID of any errors you suspect are contributing. Click on the Services tab in Task Manager. Sort the list by process ID. To identify the cause of your malfunction, you can compare your suspicious procedures with this list.

2- Too Many Background Processes

Background processes are a part of every computer. They run automatically without opening the user. As more and more applications are downloaded to the computer, these background processes start accumulating and consuming significant amounts of CPU resources. You can stop these background processes by checking them in the Startup tab and then restarting your computer. This will prevent them from starting automatically every time you turn on your computer.

3- An Antivirus or a Virus

There are many reasons for high CPU usage. Some of them can be surprising. Processing speed may be slow due to your antivirus program or virus. If you have an older OS or device, constantly scanning your hard drive for potential threats can drain your CPU power. Your antivirus might be causing your device to lag at random times. You can prevent viruses from running on your device by using your antivirus scheduling feature to make sure it scans at times when you’re unlikely to use it.

Your computer may also contain malware. This could be a background process or an attempt to spread itself through email and social media. Identifying viruses on your computer can be difficult. Even scanning your device with antivirus software may not work. Many forms of malware contain something called “antiforensics,” which prevents them from running when security software is installed on your device. You can either scan with several antivirus programs or remove the virus manually. As well as you can check for more info about antivirus programs


The most common problem that can affect computer performance is high CPU usage. However, identifying the root cause can be difficult if you don’t know where. If you continue to experience high CPU usage even when using standard processes, you may need a faster computer. You can reduce the CPU load by increasing the RAM. This allows your computer’s ability to store more application data. This can reduce the number of internal data transfers as well as new memory allocations. It can also give your CPU some much-needed rest.

Even everyday users can learn to troubleshoot common CPU problems, saving IT time and restarting production as quickly as possible.
