Are your computer’s fans constantly exceed their maximum speeds? Does your computer experience a slowdown or do you find that your CPU utilization is at 100 percent? It’s a bit annoying, especially when you’re not doing any work.

Generallyspeaking, you can prevent over-utilizing your CPU by avoiding heavy-duty applications. Sometimes an issue could cause your CPU to spiral out of control like the notorious WmiPrvSE.exe. Most of the time it is possible to resolve the issue that caused it and decrease the amount of CPU used as we’ll explain how to do it.

What is The CPU?

It is the CPU (central processing unit) commonly referred to as the processor is your computer’s brain. It is responsible for all the active processes. Similar to your brain it may be overwhelmed when bombarded by numerous processes, or if an individual task requires too much attention. As you might have trouble focusing when you’re overwhelmed and overwhelmed, your processor may slow down to an absolute halt when it is flooded with too many tasks it in a single go.

Let’s take a look at what’s causing the CPU off.

Why is it risky to have a high use of your CPU?

The fact that your CPU is nearly at its maximum isn’t just an inconvenience. It’s very risky. When your PC is under such high load for prolonged period of time the computer could start to overheat, causing damage to its components.

In particular, if you do not have a good cooling device, the processor could become overheated to the point that cause physical damage on the machine. This could lead to further problems and also a significant expense when you have for replacement of your CPU and maybe other components too.

If your computer is overheated it’s very likely that there’s a chance that you’ll lose any open files which haven’t been saved. This could cause you to lose hours upon working hours. (Make sure you use the save button frequently!)

In addition, no one likes an unresponsive computer. If you’re putting too much load on your CPU it won’t be able function at high speeds since there’s no room to perform tasks.


The first step is to Save your work and then restart your computer. “Turn it off and back on again” is the standard advice for troubleshooting to solve a problem. This could solve the problem, particularly in the event that it’s been a long period of time since your last reboot — a restart could clear temporary files, and could even stop the slowdown of long-running processes.

End Processes or Start Processes

Launch the Task Manager (CTRL+SHIFT+ESCAPE). If a program started increasing the amount of CPU used even after restarting then Task Manager is one of the most efficient ways to monitor it.

It is important to note that full-screen programs such as games can sometimes divert attention on the Task Monitor (hiding them behind their own windows). To avoid this you must select “Options” on the menu bar at the top and select “Always on Top”. When you’ve got a different monitor you could also move over the Task Manager window to it.

When you’re inside the Task Manager Click the Processes tab on the top. Click “More information” on the lower left to display the background Windows processes. Find”CPU” in the “CPU” column at on the right side on the Processes tab, and then click it to sort the list by CPU utilization:

It is possible to expect high CPU usage when playing games, using a video editing or streaming software, conducting the antivirus check, or when you are juggling multiple browser tabs. If you’re facing such a typical, high-CPU usage scenario, you must shut down all background applications and tabs you’re not using, then go to Task Manager and check whether the situation has changed.

It’s crucial to be aware that a high use of CPUs when multitasking may be normal. Modern CPUs can handle multitasking by dividing tasks across many processor cores, which run through various sets of instructions at the same time. Intel(r) Hyper-Threading Technology (Intel(r) HT Technology) takes the process a step further by making several “threads” that execute on each core that is able to handle different tasks. If the use of CPUs by the program that’s heavy-duty, such as Adobe Premiere is high, it might be making use of the CPU cores that are at its disposal.

Intel(r) Turbo Boost Technology Intel(r) Turbo Boost Technologycan aid in processing large workloads by dynamisally increasing the speed that your processor. Intel(r) Core(tm) the X-series processor family has another feature to reduce the chance of slowdowns because Intel(r) Turbo Boost Max Technology 3.0 automatically assigns the most demanding tasks to your processor’s fastest cores, in addition to increasing the speed of these cores.

These processors can dramatically improve performance when multitasking as well as working with demanding software, but instances of excessive CPU usage are still possible. If you notice background processes with name such as Runtime Broker, Windows Session Manager or Cortana in the upper right corner in the column of CPU after you reach 100% CPU utilization you may have a problem.

These Windows programs are engineered to consume a small amount of your memory or processing power under normal conditions — you’ll typically see them using either 0% or 1 percent on Task Manager. When your computer is not in use the entire process in total will take less than 10 percent of your CPU’s capacity. But, unexpected or glitchy behaviour — like the case of a Windows process trying to complete a search which has been deactivated in another program — could result in a process taking almost all of the resources of your system.

After you’ve launched Task Manager and found the process that you didn’t expect to be using an enormous amount of CPU, use the internet for the process to pinpoint the source. You shouldn’t end a process such as explorer.exe (which manages a number of graphic elements, including the Start menu and desktop) as well as winlogon.exe (startup tasks as well as the CTRL+ALT+DEL display) in the absence of some reason to do so.

Once you’ve identified the task as not critical (and once more, verified that you’ve saved what it was you worked on) Click on the process to choose it, and then select End Process in the lower right on Task Manager. End Process will cause the process to stop without saving.

Update Drivers

If a particular process is taking up too much CPU, consider upgrading your drivers. Drivers are programs that manage specific devices that are connected to the motherboard. The update of your drivers can eliminate problems with compatibility or increase CPU use.

Navigate to the Start menu and then Settings. Select Updates and Security, and then click”Check for Updates” and finally click the “Check for Updates” button. This will update the drivers that are critical to your. Graphics card manufacturers also offer software (such such as NVIDIA GeForce Experience to GPUs) that can improve the overall performance of games.

Certain bugs that are rare can be addressed by re-updating your BIOS version. It’s the BIOS (Basic Input Output System) is a firmware that’s installed on the motherboard which sends instructions to other computer components when it starts up. Since changing the BIOS typically doesn’t bring enhancements in performance (and could cause new problems) it’s best to only do this after you’ve discovered the issue that is causing excessive CPU use and discovered an BIOS update that specifically solves it.

Scan for Malware

If the issue continues the issue is due to malware that disguises itself as an ordinary Windows process. Certain malware programs use the CPU or GPU bandwidth to serve different motives (for instance mining cryptocurrency) and appear in Task Manager with a name that is familiar such as “Cortana.exe” as well as “Runtime Broker”.

Conduct a complete scan using your preferred virus software to determine if this is the case. The security scan that is offline and for free through Windows Security (running within the taskbar of your computer and Windows setting) is an excellent option.

Power Options

Certain settings in the power menu can slow the performance of your CPU regardless of whether you’re using a laptop or a desktop. You can check Your Power Options by clicking on the Start menu and then typing “Edit the Power Plan”. When you are in the edit mode then select “Power Options” in the address bar located at near the bottom of the screen. The screen should look like this:

Choose “Show other plans” and then select the non-power saver option.

Then, open Task Manager once more to see if your CPU usage resumes normal.

Get Particular Guidance Online

There are a variety of processes that can cause the high use of CPU and there’s no standard solution. For specific guidance find your name and the title of the procedure from the Details or Processes (a more precise view) tab in Task Manager. Then, search online for support forums regarding the subject.

If you’re not seeing any results from your initial search include any specific details that may aid, like what model your computer is (listed alongside “Processor” within System Information), and the names of any other programs that may be causing the problem. It’s very rare to discover an issue that hasn’t been mentioned in hardware or gaming forums and gaming forums, so make sure to play around with a few variations to your search.

Reinstalling Windows

If you have a restore date before the date your issues with your CPU started Try using it. However, because Windows shuts System Protection off by default and most of us do not.

In this scenario, the last option could be to reinstall Windows. This is a long process, but it could possibly resolve issues with CPU usage that are caused by software.

Microsoft’s “Reset the PC” will disable all your applications, leaving your personal files in place. After that, you’ll need to install all applications that you don’t run on Windows and the settings you’ve made in the programs will be deleted unless you save and backup them. To be safe you need to backup all of your personal files whether on the external storage device or via cloud-based storage.

If you’re ready to start you can click the Start button, and input “Reset the PC”. After that, click “Get Start”.

The process can take up to one hour or more. Once it’s completed you’ll need to install any programs that you have installed.
