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.

Error CausesError codes on Windows devices can result from many reasons, including lack of proper PC maintenance, the presence of malware, and issues related to servers. In the case of error code 0xc00007b, it manifests itself on various versions of the Windows operating system when users attempting to run applications incompatible with their system or use the incorrect bit location. To correct these issues that may be causing error code 0xc00007b, users will need to use manual repair methods listed in this article. Failure to rectify this error code could result in others such as error code 0xc0000142.
The manual repair procedures listed in this article do not require extensive technical knowledge. Thus, even average Windows users will be able to apply these solutions in order to fix error code 0xc00007b in Windows 8. However, in case of difficulty applying the solutions listed below, contact a Windows repair technician.
One of the first manual repair methods you can attempt is to use Windows Update. This will enable users to access the latest updates for the version of Windows they have on their system. To update your system, follow the instructions below.
After you’ve completed the installation of the latest updates, reboot your machine then attempt to run the gaming application you were unable to open due to error code 0xc00007b. You should be able to run the application if Windows Update fixed the issue. However, if the error code reoccurs, proceed to the next manual repair method by installing Microsoft DirectX.
Another important manual repair method relates to the use of DirectX, a free tool available to Windows users regardless of the version of the Windows operating system present on their PC. Visit Microsoft’s official website and search for DirectX End-User Runtime Web Installer. Ensure you access the latest version of the program, then click download.
The app enables Windows users to access high-speed gaming by providing a powerful platform for games and multimedia applications. Access to the latest version of DirectX can help users fix the issues causing error code 0xc00007b in Windows 8.
When the installation process is complete, reboot your PC, then proceed by checking if you are able to run your gaming applications. If you are still unable to run the applications the issue will need to be resolved via another manual repair method.Access the latest version of Microsoft’s .NET Framework to complete the final manual repair method. Be sure to follow the steps listed below to download the latest version of the .NET framework. This is crucial as only the latest version of the framework is equipped with the necessary capabilities required to successfully address the issues causing error code 0xc00007b on your device.
Restart your computer after you’ve downloaded the latest version of the .NET framework. Open the gaming application you were previously unable to run due to error code 0xc00007b.
You’ll be able to access all your gaming or multimedia programs if the issue was resolved via this manual repair method. Otherwise, you may need to reinstall the programs you are unable to run as there may be an issue with the program itself resulting in software conflict or the inability to run other gaming programs.
If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.
“An error occurred when unpacking, Unarc.dll returned error code -1, ERROR: archive data corrupted (decompression fails).”If you encounter the isDone.dll error message on your Windows 10 computer, then read on as this post will show you how you can fix it. This error has something to do with the incomplete installation of PC games or files of larger size. The ISDone.dll error appears due to faulty Unarc.dll file residing in the System32 folder on 32-bit operating systems and the SysWOW64 folder on 64-bit systems. So, if you see this error message, then, it means your computer was not able to read installation archive files.
