Why Is My CPU Usage at 100%?
If your CPU usage is at 100%, the processor is working at maximum capacity. The processor is working in a capacity more than it’s capable of.
This results in slowdowns, lag, stuttering, and other systems such as CPU overheating.
Some of the reasons your CPU usage is at 100 include:
- Resource-Intensive applications. Some applications are highly demanding on your device. Some of the applications include graphics and video editing tools. Your CPU can become slow if the apps are trying to run simultaneously.
- Malware and viruses. Sometimes your computer can start lagging due to a virus or malware attack. Since they run discreetly, they can use your CPU resources without you noticing.
- Some applications continue to run in the background even after closing them. They can run in the background without notice. If several run simultaneously, they can eat up your CPU resources.
- Improper hardware configuration. Your CPU usage can be at 100 due to some hardware configuration issues. For instance, if your computer is configured to use onboard graphics instead of the dedicated video card, you can have issues with a patch that changes the settings.
- Dirty cooling systems and fabs can cause your CPU to lag. A hot CPU finds it hard to do its job, and it’s more likely to crash. You can resolve the performance issues by cleaning the vents of dust buildup, cleaning the heat sinks, and clearing obstructions.
How Do I Lower My CPU Usage on Windows 10?
High CPU usage can cause applications to stop reacting to new inputs, make games stutter or crash, or open programs slowly.
If you want to fix the high CPU usage on Windows 10, use the following steps:
Reboot the Device
Restarting your PC can help deal with lagging issues.
Start by saving your work and then reboot the device. The process can help deal with the issues, especially if it’s been a long since you last restarted the PC. Restarting the device helps clear temporary files and resolve sluggishness in long-running processes.
Restart or End Processes
Restarting or ending particular processes can also help in dealing with the issue.
How do you restart the processes?
Go to the Task Manager by pressing CLTR+SHIFT+ESCAPE. If a program continues to misbehave after a restart, Task Manager offers a simple tracking method.

When the Task Manager is open, go to the top and click the Processes tab. At the top of the Processes tab, go to the CPU column and click on it to get CPU usage. Click “More Details” to reveal the background Windows processes.
If you perform an antivirus scan, video editing, streaming applications, or several browser tabs, you’ll have high CPU usage. You can remedy the high CPU usage by closing all the programs that aren’t in use.
However, high CPU usage isn’t out of the ordinary if you are multitasking. Furthermore, modern CPUs can handle multitasking by splitting processes between various processor cores.
The split processor technologies enhance the speed of multitasking.
The high CPU usage on your device may be due to un-updated drivers. Drivers help to control the devices connected to the motherboard.
Updating the drivers can help deal with bugs that lead to high CPU usage and enhance compatibility.
If you want to update your drivers, start by opening the Start menu and going to the Settings. Next, click on Updates and Security and look for the “Check for Updates” button. The process helps in updating all the vital drivers.
