There is a high chance you may have heard of the CPU before, but we will save you from googling the term. CPU signifies Central Processing Unit. Some people call it a processor or microprocessor in a computer.

What is CPU?

Still hard? Why don’t we model an analogy? We, as homo sapiens, can be developed and intelligent thanks to our primary “processor” – the brain. It does all the work and sends signals to other organs so we can function correctly.

Technology is no different. The CPU is the brain, located in the motherboard, of any digital computer system's hardware. CPU consists of multiple microscopic transistors that regulate the electrical flow through the integrated units.

Everything starts with any input device, or from a system or an application software program (for example, your operating system or web browser). After, the CPU handles the required tasks to carry out the instructions.

We will give you an instance, if you want to write an email to your manager, check some information in your browser, or even play a video game on your computer - the CPU will deliver the instructions to the programs to commence the actions.

Do other devices has the CPUs?

How to fix high CPU usage

A computer is any device that automatically performs logical operations or sequences.

The CPUs, regardless of the manufacturer, perform all the logical operations for any digital device and even gaming console.

High CPU usage: What does this indicate?

As mentioned earlier the CPU is a vital part of any modern device. But can it keep up with the number of actions that we as users demand?

Sure, any computing device is a machine that is supposed to give us time-effective and coordinated results. Bear in mind that your computer's programs share the same CPU time and memory. The more programs you have or install on your computing device, the higher the chances are that the system will have high CPU usage.

Any operations, which function in windows without the user opening them, consume a portion of the CPU on every computer. However, over time and as more programs are downloaded, these background processes can assemble and start consuming some resources.

The maximum amount of CPU use is 100 percent. When the mark on the processor reaches up to 100 percent, the CPUs start to indicate the stress point.

For example, if you have around 100% CPU usage on Windows 10, the installed programs will be running slowly.

As we said earlier, it is not an individual case. Most of the time, it can be quickly fixed.

How to fix 100% CPU usage?

When the fan on your computer is constantly running at full speed, your CPU is operating at 100%. Eventually, the computer might be slower. Especially if you don't take any action, this is annoying.

Below you can fix handy tips on how to stop high CPU usage.

If the problem still exists, we advise scanning your device for malware. Usually, malware can impersonate a standard Windows process.

It goes this way. Some malicious apps appear in Task Manager with familiar names, however, they need different amounts of CPU and GPU bandwidth.

In Task Manager, under the Details tab, monitor the “CPU” column, If you notice a program with a sketchy name and a noticeably high CPU – immediately scan your device for viruses. Run a reliable AV software or an anti-malware application to solve this issue.

Is high CPU usage bad?

Long story short: yes, it's not good for your device. But it's a normal practice for any computing device. If you are running too many programs on your gadget then high CPU usage is anticipated.

Which are the most CPU-intensive applications?

If you have got too many apps on your device then a high CPU is irreversible. So lags and flaws are inevitable. Try to close all running apps so that your system has the breathing room it needs to manage these resource-intensive tasks when necessary.
The most infamous CPU-intensive software includes those applications that use video and photo editing tools, software for encoding and decoding, a lot of plug-ins, etc.

Can I track CPU usage?

Nearly all server operating systems have a performance monitor that allows you to view the CPU use at any given moment. When keeping track of a server's CPU utilization, you should keep an eye out for spikes because they can be signs of unusual activity.


We are aware that it could be difficult to locate high CPU consumption. In this article we described the most familiar signs of high CPU usage: the workstation may heat up as it struggles to carry out tasks, the cursor is slow and erratic, apps shut down and glitch, and so on.

As we said, even common people can learn about typical CPU issues and how to fix them.

Hopefully, by now, you have a clearer idea of what CPUs are, what they perform, and why they are so crucial. Additionally, we believe that our detailed guide on how to fix 100% CPU usage in Windows 10.
