Have you encountered a program called System Interrupts on your device manager? Does this show high CPU usage on your system? Many Windows users have reported that system interrupts occur when CPU usage is high.
This guide will help you understand what system interrupts are and how to fix system interrupts with high CPU usage in Windows 10.

What Are System Interruptions?

System interrupts refer to a placeholder that indicates the system resources used by hardware interrupts occurring on your PC. Additionally, system interrupts are part of the programs that appear when you open Windows Task Manager. It’s also a Windows background processing program that you might not even notice. System interrupts are essential program components of the Windows operating system that manages the communication between the Windows operating system (system) and computer hardware.
System interrupts function as an alarm system (alarm system) for the CPU. It notifies or reminds the CPU of any high-priority scenario that requires the attention of the CPU. The CPU then stops or pauses its immediate task and registers it to perform that high-priority task, and does not return to the other job until the important task completes.
It means that while system interrupts appear to be a PC process, they are not. If the system interrupts consume up to 10% and more than the processor, you may need to be careful as this indicates a hardware failure somewhere.

Does The System Stop a Virus?

No. System interrupts are not a virus. It is an official and vital Windows component that coordinates the Windows system and computer hardware. Usually, the process of system interruption shouldn’t be consuming too much of the computer’s CPU power. However, some users reported high CPU usage during system interruptions in some cases, leading them to believe it was a virus.
Also, system interrupts are not an actual process and are not associated with running EXE or DLL files. No malware or viruses can hijack them directly. However, there is always the option that a particular malware or virus could interfere with a specific hardware driver, affecting “system interrupts.”

2. Scan your PC’s antivirus or anti-malware software to remove any malware or viruses that may be interfering with your hardware and causing the problem.
3. Disconnect or disable any attached external devices: Many external hard drives, e.g., B. a hard drive. B. USB can lead to high CPU usage in the event of system interruptions. Disabling these external devices can help resolve the problem.
If these workarounds don’t work, try the following effective fixes that have helped many other users fix system interruptions on their PCs.

Fix # 1: Disable USB Root Hubs

How to disable Roots USB hubs, i. H. Prevent the CPU from being interrupted by external hardware:
1. Press Wins + S to open Windows Search and access Device Manager.
2. Click on Device Manager
3. Go to Device Manager, find Universal Serial Bus Controllers.

4. Select Update Driver then it “Automatically check for updated driver software.”
Windows starts the driver update process. Wait for this driver update to complete and do the same with the other device drivers. Restart your PC and check if the system interrupt problem persists.

Fix # 3: Disable Internal Devices

Instead of randomly updating your device drivers, you can first disable individual device drivers to find the culprit. If you are thinking of potential violators, you can turn them off first. Otherwise, some of the internal devices that you may need to disable (common culprits) include:
1. Network adapter
2. Internal audio devices
3. Internal modems
