How is the CPU usage calculated

Windows CPU usage at 100% - you can do that


Your computer suddenly freezes all open programs and nothing works anymore? This could be because the CPU is being used too much. Aside from consulting the Task Manager, the first responder in this case, there are other factors you should consider to avoid or resolve high processor usage. In this article, we will show you how high loads can occur and what you can do about it.

Reasons for high CPU usage

If you start one or more programs, Windows automatically distributes the processing load on the CPU. Under certain circumstances, programs can take up more and more space on the processor. If the CPU load becomes too high, the system freezes and the open programs can no longer be operated. Another cause can be graphic programs such as animation software or games with high-resolution graphics. Other programs that are often the reason for high CPU utilization are 3D renderers, video programs and converters, or CD and DVD burning programs. Even the browser can exceed the processing power of your processor. The reason for this may be too many open tabs or additional addons and plugins. In addition to the manually started programs, there are often background processes that place a load on the CPU. Finally, missing drivers, e.g. for the motherboard chipset or your graphics card, can also be a cause of high CPU utilization.

What is my current CPU usage?

To check the current utilization of your CPU, you can simply use the Task manager to open. To do this, press the buttons [Ctrl] + [Shift] + [Esc] and then switch to the tab "power". The CPU utilization is then shown graphically under Windows 10.

How to reduce the load on your CPU

The easiest way to reduce CPU usage is to close unnecessary programs and applications. If your PC is frozen, you can still use the to close the programs Task manager call.

The task manager shows you in the tab "Processes", which programs generate a particularly high CPU load. By using a select individual program and then on "End task"Click, you can test whether that helps. If not, all programs should be closed.

You can also clean up your system's startup programs. This ensures that the CPU load does not get too high when you start your Windows PC. Also, auto start will be frequent Background processes started that are waiting to be used, but are often not used. The CPU is still being used to capacity. When terminating background processes, be sure to only terminate third-party processes (e.g. Dropbox). Killing native processes could lead to errors in your operating system.

Another tool is the CPU-Z tool. This enables you to determine the hardware installed in your PC and then install drivers or, if necessary, update your drivers.
