How To Fix ‘System Interrupts High CPU’ Usage Issue


System Interrupts appears as a process in Task Manager despite being a Windows feature, although it is unquestionably not one. In actuality, it’s just a placeholder for all of the hardware interruptions that aren’t happening on your computer.

Every computer has embedded hardware interrupts, which determine how many tasks can be run at the same time. Hundreds of processes can run at the same time on your computer.

Interrupts are also used to speed up the execution of instructions, and they can be used by processes to notify the CPU that they are ready for execution by delaying the activity of other processes.


All hardware interrupts in the process can be examined for CPU utilisation. System interrupts can be thought of as a kind of alarm system for CPUs. System interruptions typically consume between 0.1 and 2% of the CPU, although they can occasionally reach as high as 7%, which is also considered normal.

In contrast, in typical circumstances, the process System Interrupts should not rise more than 2-3 percent. If the process begins to roll to roughly 20% and then stops, you should pay attention since it suggests a problem, as it implies the occurrence of a hardware malfunction.

Some disaster-prevention steps are listed below. They’re listed in order of difficulty from easiest to most difficult.

Fixes For High CPU System Interrupts

Take a look at it.

1. Disabling USB Root Hubs 

Root Hub isn’t a physical device into which you can insert a USB peripheral. It is, instead, a software driver that allows you to connect a variety of USB peripherals to your computer. Multiple USB root hubs are found on many computers, allowing multiple devices to share the data bus.

The first step in removing any USB root hubs that aren’t in use is to figure out which USB root hubs are connected to your keyboard and mouse. We’ll figure it out as soon as possible, and then disable all of the extra root hubs while we look for a solution to the excessive CPU utilisation.

To disable USB root hubs, i.e., to prevent external hardware from interrupting the CPU, follow these steps:

Step 1: Right-click the Windows start menu and select Device Manager from the drop-down menu.

Step 2: Locate the Universal Serial Bus Controllers dialogue box and double-click it to expand it.

Step 3: Right-click the USB Root Hub and select Properties from the drop-down menu.

Step 4. Go to the Power tab and see if your mouse and keyboard are using this root hub; if they aren’t, disable it. Also, save for the one for your keyboard and mouse, disable all other root hubs.

Return to the task manager after removing your USB Root Hubs to see if the system interruptions high CPU issue has been resolved.

2. Disabling Audio Enhancements

To improve sound quality, many sound drivers employ improvements. If these properties aren’t compatible with your computer, it might lead to major issues like the CPU utilisation we’re seeing right now. It could be worthwhile to turn off the audio enhancements and see if the CPU consumption drops.

This feature isn’t available in all sound drivers, though. The Enhancements tab appears to have been renamed Sound Blaster. On the other hand, we may try turning off the audio effects.

Some sound drivers are concerned by the “Exclusive mode” option, which allows other apps to have complete control over your sound card. This isn’t supposed to be a bump, but it’s worth a shot to see whether it solves our problem.

Follow the procedures below to see if the Windows system interrupts high CPU use problem has been resolved.

Step 1: Place your finger on the Windows + R button to activate the Run In dialogue box. In addition, type “Control Panel” to eject the programme.

Step 2. In the control panel’s placeholder, put “sound” into the search bar on the upper right side of the screen, then select the sound option.

Step 3: Select the audio device that is connected to your computer from the list of sound options that appears on the screen. Finally, right-click and select Properties from the drop-down menu.

Step 4. Next, navigate to the Enhancements tab and uncheck all of the enabled enhancements (instead, click the option that says “Disable all enhancements”).

Step 5. Select the Advanced tab on the edge and uncheck the exclusive mode, which allows applications to override the settings. Finally, save and exit the programme.

If this isn’t working for you, try turning these options back on and moving on to the next technique.

3. Disabling The Wake on Magic Packet Settings

Is it true that things like Magic Packets exist? Yes, Magic Packet is really genuine. After receiving the Magic Packet from the local network, it is a message for your machine to awaken from standby or sleep state. You may have heard the term “Wake On LAN” before (WOL).

Despite this, this feature is known for causing high CPU utilisation concerns because it indicates that a large number of interrupts are induced and the system must account for each one. So let’s turn off the feature. If this does not produce the desired results, you may always turn it off later.

Step 1: Press Windows + R on your keyboard to open the Run application on your computer. Enter “devmgmt.msc” and press Enter. The device manager for your PC will appear on the screen.

Step 2. Finally, select Network Adapters from the drop-down menu to see a list of additional devices.

Step 3: Select the Ethernet device in addition to the WiFi device, right-click it, and select Properties from the menu that appears.

Step 4. Finally, go to the Advanced tab, where you’ll see a variety of options, and select the one that says “Wake on Magic Packet.” Select the Disabled option, save your changes, and exit.

If your computer needs to be restarted, do so without hesitation and see if the problem has been resolved.

4. Installing Intel Rapid Storage Technology

Intel Rapid Storage Technology is a Windows-based application that improves the performance and reliability of SATA-equipped desktop, mobile, and server computers. You can expect increased performance and decreased power usage with the introduction of SATA disc drives.

Users have occasionally stated that installing the Intel Rapid Storage Technology module fixed their problem. It’s simple to set up, but keep in mind that it changes the SATA controller driver on your computer. If you are familiar with the mechanics, you can get the module from Intel’s official website.

5. Disabling Fast Startup

The Fast Startup feature in Windows 10 operates similarly to the hybrid sleep mode in prior Windows versions. It combines the advantages of cold shutdown with hibernation. When you shut down your computer for the first time, Windows logs off all users and stops all applications, similar to a cold boot.

When this is done, Windows will be in the same state as it was when it was first started (because all users have been logged off and all applications have been closed). Despite this, the system session is up and running, as is the kernel.

Windows does not need to refresh the kernel, system state, or drivers when restarting the computer. Windows notifies device drivers and preserves the current system state when you prepare the computer for hibernation. It just reactivates the RAM with the image loaded from the hibernation file and takes you to the starting screen.

We can try to disable this feature because it does not completely shut down your computer as we would anticipate. This has aided a large number of people in quickly resolving the high CPU disaster.

Step 1: Press Windows + R on your keyboard to open the Run application. Type “control panel” into the appropriate space and hit Enter. The launch of your computer’s control panel will be completed in this manner.

Step 2: Select Power Options from the Control Panel’s other options.

Step 3: Select the option Choose what the power buttons do on the left side of the screen.

Step 4: From the drop-down menu, select the option Change Settings, which is presently inaccessible. Administrative privileges are required for this task.

Step 5: Uncheck the box next to it at the bottom. Fast startup should be enabled. Finally, quit and save the modifications.

Restart your computer to see if the system interrupts and the high CPU problem has been resolved.
