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.
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.
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.
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:
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.
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.
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.

TCI/IP or as known as Internet protocol is one that controls packets that are sent over the internet and makes sure that each one has reached its destination so you can pleasantly browse your favorite websites. The setting for the given protocol is stored locally on your machine and most of the time, everything works fine and good, but sometimes, these settings can get corrupted.
Malware or other software can temper with setting making TCP/IP making it wrong and throwing nondescript connection errors in your face. If you are faced with this issue worry not because fixing this issue is really easy.
Before we actually go and fix the issue please do scan your system with your protection suite just to be sure that if there is any kind of malware on the system it is properly removed from it.
First thing is to open search and find PowerShell, press the Windows key on the keyboard, and type in PowerShell so search results are shown. Click on Run as administrator to open PowerShell in elevated mode.
Once PowerShell is opened type indie it:
netsh IP reset and press ENTER. The task will start executing and at this point you will see a lot of Resetting, OK! messages. Once everything is finished restart your PC and you are good to go.
