Fix System Interrupts high CPU usage

System Interrupts are operating system processes that function as an alert system for the CPU. So whenever a scenario needs the attention of the CPU, it alerts the CPU about it. In turn, the CPU suspends what it is doing, saves it, and then takes care of that important job and once that job is completed, it resumes back to what it was doing. This indicates that although System Interrupts appears as a process, it’s actually not. As a matter of fact, it is like a manager that reports to the CPU about all interrupts that happen on a hardware level, e.g. hardware interrupts. And if there are lots of interrupts, this means that there might be various errors occurring on a hardware level. As a result, it may take a lot of system resources. And if you consider disabling System Interrupts, stop right there as your computer will almost become useless without it.

So if you see System Interrupts consuming high CPU usage in your Windows 10 computer, you can fix it without having to disable it and cause more problems. If System Interrupts takes up more than 5 to 10% of CPU, then you definitely have a problem. This could be happening due to some hardware or driver issue. The first thing you can do is to try rebooting your computer once and see if the issue comes back or not.

High CPU usage of System Interrupts is a huge backlog for the CPU and it stays in the loop. If a simple system restart didn’t fix this issue, here are some suggestions you can try.

Option 1 – Try to update the hardware drivers

As stated, the problem might have something to do with hardware drivers so you can try to update these drivers and see if it works.

  • Reboot your computer into Safe Mode with networking support.
  • Tap the Win + R keys on your keyboard to open the Run dialog box.
  • After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
  • After opening the Device Manager, update all the outdated Hardware drivers on your computer.
  • Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
  • Now restart your PC and check if the BSOD error is fixed or not.

Note: On the other hand, if a recent update has caused the System Interrupts high CPU usage, then you might want to roll back your hardware drivers to their previous versions.

You can check with the Windows Update History to check out any recent updates as well as the previous ones.

Option 2 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

Option 3 – Try to enable or disable Hardware

If you do not want to remove hardware, you can just disable them using the Device Manager. Note that this can also be applied to the internal hardware.

  • Tap the Win + X + M keys to open the Device Manager.
  • Next, navigate to the device you want to disable.
  • Then right-click on it and choose to disable the device.

Note: Make sure that you disable one device at a time and then give it a couple of minutes and check if there are any changes in the CPU usage to pinpoint the hardware. And if there is no change, you need to enable the device you’ve just disabled and then proceed to disable the next hardware device. If there are changes, then it’s probably the culprit. Just keep in mind that you must no disable any device that is needed to keep your system up and running.

Option 4 – Try to update the BIOS/UEFI

Updating the BIOS/UEFI can help you fix the high CPU usage of System Interrupts but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “msinfo32” in the field and press Enter to open System Information.
  • From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
  • After that, you should see the developer and version of the BIOS installed on your PC.
  • Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
  • If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
  • Now double click on the downloaded file and install the new BIOS version on your computer.
  • Restart your computer to apply the changes made.

Option 5 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:

  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.
  • Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Performance Troubleshooter:

  • Tap the Win + R keys to open the Run dialog box.
  • Type “exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
  • Then click on Next to get started. Wait until the process is completed.

Preventing installation of Removable Devices
In case you don’t know, Windows 10 supports installation and use of a number of removable devices which includes plug and plays mouse, keyboard, and other USB-based devices. But this could actually pose a threat to the integrity of a computer system and thus, some organizations pose a restriction in using these kinds of devices. the restriction on these devices is also useful especially if you keep on leaving your computer idle and someone tries to mess it up by plugging in a removable device. In such situations, the restriction will defend the user against data theft. Thus, in this post, you will be guided on how you can prevent the installation of removable devices on your Windows 10 computer. There are two options that can help you in preventing the installation of any removable devices on your computer – you can either try to use the Registry Editor or use the Group Policy Editor instead. Follow whichever option you want to use the instructions given below but before you start, don’t forget to create a System Restore Point first.

Option 1 – Prevent installation of Removable Devices via Registry Editor

  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsDeviceInstallRestrictions
  • From there, look for a DWORD named “DenyRemovableDevices” and set its value to “0”. On the other hand, if you can’t find this DWORD, just simply create it and set its value to 0.
  • Once done, exit the Registry Editor and reboot your PC to apply the changes made.

Option 2 – Prevent installation of Removable Devices via Group Policy Editor

Keep in mind that the Group Policy Editor is not available in the Home Edition of the Windows operating systems. Thus, if you are using one, just stick to the first option, otherwise, proceed to the following steps.
  • Tap the Win + R keys to open the Run utility and type “gpedit.msc” and click OK or tap Enter to open the Group Policy Editor.

  • Then select each one of them and double-click to open a new mini window.
  • After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
  • Now restart your computer to successfully apply the changes made.

Option 2 – Try to update the Network drivers

If the present Network driver is giving you a headache that is the “DRIVER IRQL NOT LESS OR EQUAL or SYSTEM THREAD EXCEPTION NOT HANDLED, Netwtw04.sys failed” BSOD error, then you need to update the Network drivers. To do so, here’s what you have to do:

  • Then right-click on each one of the Network drivers and update them all.
  • Restart your PC and see if it helped in fixing the BSOD error.
Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Netwtw04.sys failed BSOD error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:
  • Open the Command Prompt as admin.
  • Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
  • The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the CHKDSK Utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.
