Što je to proces prekida sustava^{(System interrupts)} ? Vidite li sustav^(System) prekida koji troše veliku potrošnju CPU-a^{(high CPU usage)} u Windows Task Manageru^{(Windows Task Manager)} ? Je li to virus ili zlonamjerni softver? Pa^(Well) , sustav^(System) prekida proces OS-a, a ako se nalazi u mapi System32 , nije zlonamjerni softver. Ako se nalazi negdje drugdje, moglo bi biti. U ovom vodiču pomoći ćemo vam razumjeti prekide sustava^(System) i kako popraviti prekide sustava^(System) visoke potrošnje CPU -a u sustavima Windows 10^{(Windows 10)} i Windows 11 .

Što su prekidi sustava^{(System Interrupts)} u Windows 11/10

Prekidi sustava su poput sustava upozorenja za CPU . Ako scenariju treba pozornost CPU -a , on mijenja CPU oko toga. CPU tada obustavlja ono što radi, sprema ga i brine se za taj važan posao. Nakon što je posao završen, vraća se na ono što je radio.

To znači da iako se sustavni^(System) prekidi pojavljuju kao proces, nisu. Zapravo, to je poput upravitelja koji izvještava CPU o svim prekidima koji se događaju na hardverskoj razini, tj. hardverskim prekidima. Puno prekida znači da bi se moglo dogoditi mnogo pogrešaka na hardverskoj razini, i to je razlog zašto oni počinju uzimati puno resursa.

Zamislite puno zaposlenika (hardvera) pod upraviteljem ( sustav^(System) prekida). Sada mu se svi zajedno počinju žaliti (prekidaju) o svojim pojedinačnim problemima, a administrator^(Admin) sve zahtjeve gura CPU -u ( šefu^(Boss) ). CPU se neće moći nositi s tim zajedno i postati preopterećen.

Nikad ne razmišljajte o onemogućavanju prekida sustava. Vaše računalo će postati gotovo beskorisno bez njega.^{(Never think about disabling System Interrupts. Your PC will become almost useless without it.)}

Sustav prekida veliku upotrebu CPU-a

Ako sustavni prekidi zauzimaju više od 5 do 10% CPU -a , imamo problem. To se može dogoditi zbog problema s hardverom ili upravljačkim programom. Najbolji način da to popravite je da jednom ponovno pokrenete računalo i vidite hoće li se problem vratiti. Ponekad je to ogroman zaostatak za CPU i ostaje u toku. Ponovno pokretanje će to ponekad popraviti. Međutim, ako opet vidite da je potrošnja CPU -a visoka, evo kako ćete to popraviti.

Bit će teško shvatiti koji hardver uzrokuje probleme. Stoga će za ovo popravljanje trebati i strpljenje i vrijeme.

1] Ažurirajte upravljačke programe hardvera

Moguće je da problem uzrokuje rouge hardverski upravljački program. Dakle, vrijeme je da ga ažurirate.

• Idite na Settings > Update i sigurnost^(Security) .
• Provjerite čeka li ažuriranje vezano uz upravljačke programe. Ako da, ažurirajte ih sve.

2] Povratni hardverski upravljački program s

Ako je nedavno ažuriranje upravljačkog programa pokrenulo ovaj problem, možete vratiti upravljački program na prethodnu verziju^{(rollback the driver to its previous version)} . Možete provjeriti povijest ažuriranja sustava Windows kako biste saznali koja nedavna ažuriranja. Moguće je da novi upravljački program ima neki neprijavljen problem i da nije kompatibilan s trenutnom verzijom sustava Windows .

3] Isključite vanjski hardver^{(3] Unplug External Hardware)}

Sada kada ste sigurni da upravljački programi nisu problem, vrijeme je da uklonite vanjski hardver poput miša, tipkovnice, pisača, vanjskog tvrdog diska, web kamere i tako dalje. Pazite^(Make) da upravitelj zadataka bude otvoren i uklanjajte ih jednog po jednog. Ako primijetite da velika promjena u sustavu^(System) prekida korištenje CPU -a nakon uklanjanja određenog hardvera, tada znate krivca.

4] Onemogućite i omogućite hardver

Ako ih ne želite ukloniti, također možete odabrati da onemogućite hardver iz Upravitelja uređaja^{(Device Manager)} . To se može primijeniti i na interni hardver.

• Otvorite Upravitelj uređaja (WIN +X + M).
• Dođite do uređaja koji želite onemogućiti.
• Desnom tipkom miša kliknite i odaberite onemogućiti uređaj.

Obavezno^(Make) onemogućite jedan po jedan uređaj. Dajte minutu ili dvije i primijetite je li došlo do promjene u korištenju CPU -a kako biste precizno odredili hardver. Ako nema promjene, omogućite uređaj koji ste upravo onemogućili, a zatim prijeđite na sljedeći uređaj. Ako vidite promjenu, znate što je uzrokovalo da sustav^(System) prekida visoku upotrebu CPU -a u sustavu Windows^(Windows) .

Evo jednog savjeta. Pazite^(Make) da ne onemogućite nijedan disk^(Drive) koji je neophodan za održavanje vašeg sustava.

5] Provjerite kvar hardvera

Opet nije jednostavan način da saznate, ali možete:

• Upotrijebite SMART  alat ili   izvornu značajku sustava Windows^{(Windows native feature)} da provjerite uzrokuje li vaš tvrdi disk problem.
• Provjerite svoje napajanje.
• Upotrijebite alat za dijagnostiku memorije^{(Memory Diagnostic tool )} ugrađen u sustav Windows kako biste provjerili ima li vaš RAM problem na hardverskoj razini.
• Za drugi hardver možete koristiti Windows dijagnostičke alate^{(Windows Diagnostic Tools)} poput
  • Monitor pouzdanosti^{(Reliability Monitor)} ( Control Panel\All Control Panel Items\Security i održavanje^{(Maintenance)} )
  • Monitor performansi^{(Performance Monitor )} (perfmon.exe)

Ovi bi vam alati trebali puno pomoći da otkrijete kvar hardvera na vašem Windows 10 računalu.

6] Ažurirajte svoj BIOS/UEFI

Ažuriranja BIOS^(BIOS) -a bila su najčešće zanemarena ažuriranja prije nekoliko godina. To je uglavnom bilo zato što su se morali ažurirati izvana, ali sada kada je Windows sposoban ažurirati BIOS^{(of updating the BIOS)} ili moderni UEFI , održavajte ga ažuriranim.

Uvijek je najbolje ažurirati BIOS slijedeći upute dostupne na web stranici vašeg OEM-a. Stoga se pobrinite da znate što radite ili imate nekoga na svojoj strani tko to može učiniti umjesto vas.

7] Onemogućite Cortanu

Cortanu možete isključiti u sustavu Windows 11^{(Windows 11)} ili Windows 10 podešavanjem Windows Registry ili konfiguriranjem postavki pravila grupe^{(Group Policy)} . Učinite to i vidite hoće li pomoći.

Jesu li prekidi sustava loši?

Ne. To su sigurnosne mjere koje se primjenjuju u ekstremnim scenarijima, čime se sprječava bilo kakvo prekomjerno korištenje resursa. Također se pozivaju u opće svrhe, npr. pritiskanje tipki, za čitanje podataka, a da ništa ne nedostaje. Osnovno je da se prekidi sustava^{(System Interrupts)} događaju cijelo vrijeme, i to je dobra stvar.

Zašto sustav prekida korištenjem 100% CPU -a ?

Iako prekidi sustava^(System) ne traju dugo, ali ako se hardver ili povezani upravljački program počnu loše ponašati i ne reagiraju kako se očekivalo, tada cijeli proces ulazi u petlju uzrokujući veliku upotrebu CPU -a – jedini način da se to riješi ponovnom instalacijom upravljačkog programa ili zamjena hardvera.

Kako se uvjeriti da je korištenje CPU -a kontrolirano?

Osim korištenja aplikacije koja treba više CPU -a , najbolje je pratiti pozadinske procese. Ovi procesi obično nastavljaju koristiti CPU i iznenada se povećavaju ako zapnu. Dakle, ako ne želite da neka aplikacija bude u pozadini, svakako je onemogućite pri pokretanju. I zatvorite ako ga ne koristite.

Fix System interrupts high CPU usage in Windows 11/10

What is this System interrupts process? Do you see System interrupts consuming high CPU usage in Windows Task Manager? Is it a virus or malware? Well, System interrupts an OS process, and if it is located in the System32 folder, it is not malware. If located elsewhere, it just could be. In this guide, we will help you understand System interrupts and how to fix System interrupts high CPU usage in Windows 10 and Windows 11.

What is System Interrupts in Windows 11/10

System Interrupts are like an alert system for the CPU. If a scenario needs the attention of the CPU, it alters the CPU about it. CPU then suspends what it is doing, saves it, and takes care of that important job. Once the job is complete, it resumes back to what it was doing.

This means that even though System interrupts appear as a process, it’s not. In fact, it’s like a manager which reports to the CPU about all interrupts that happen on a hardware level, i.e.hardware interrupts. A lot of interrupts mean that there might be a lot of errors happening on a hardware level, and this is why they start taking a lot of resources.

Imagine a lot of employees (hardware) under a manager (System interrupts). Now, they all start complaining together (interrupts) about their individual issues to him, and the Admin pushes all the requests to the CPU (Boss). The CPU will not be able to handle it together and become overburdened.

Never think about disabling System Interrupts. Your PC will become almost useless without it.

System interrupts high CPU usage

If the system interrupts takes up more than 5 to 10% of CPU, we have a problem. It could be happening because of a hardware or driver issue. The best way to fix this is to reboot your computer once and see if the issue comes back. Sometimes it’s a huge backlog for CPU, and it stays in the loop. A restart will fix it sometimes. However, if you see the CPU usage high again, here is how you fix it.

It’s going to be tough to figure out which hardware is causing problems. So fixing this will need both patience and time.

1] Update Hardware Drivers

It is possible that a rouge hardware driver is causing the problem. So it’s time to update it.

• Go to Settings > Update and Security.
• Check if an update related to drivers is pending. If yes, please update all of them.

2] Rollback Hardware Drivers

If a recent update to the driver has started this issue, you can rollback the driver to its previous version. You can check with Windows Update History to figure out any recent updates. It is possible that the new driver has some unreported issue, and it’s not compatible with the current version of Windows.

3] Unplug External Hardware

Now that you are sure that drivers are not an issue, it’s time to remove the external hardware like a mouse, keyboard, printer, external hard drive, webcam, and so on. Make sure to keep the task manager open and remove them one by one. If you notice a huge change in the System interrupts CPU usage after removing particular hardware, then you know the culprit.

4] Disable & Enable Hardware

If you do not wish to remove them, you can also choose to disable the hardware from the Device Manager. This can be applied to internal hardware as well.

• Open Device Manager (WIN +X + M).
• Navigate to the device you want to disable.
• Right-click and choose to disable the device.

Make sure to disable one device at a time. Give it a minute or two and notice if there was a shift in CPU usage to pinpoint the hardware. If there is no change, enable the device which you just disabled, and then move to the next device. If you see a change, you know what was causing the System interrupts high CPU usage in Windows.

Here is a piece of advice. Make sure not to disable any Drive, which is necessary to keep your system up.

5] Check Hardware Failure

Again no easy method to find out, but you can:

• Use the S.M.A.R.T tool or  Windows native feature to check if your hard disk is causing an issue.
• Get your Power Supply checked up.
• Use Windows built-in Memory Diagnostic tool to check if your RAM has an issue on the hardware level.
• For other hardware, you can use Windows Diagnostic Tools like
  • Reliability Monitor (Control Panel\All Control Panel Items\Security and Maintenance)
  • Performance Monitor (perfmon.exe)

These tools should help you a lot to figure out hardware failure on your Windows 10 computer.

6] Update Your BIOS/UEFI

BIOS updates were the most ignored updates a few years back. It was mostly because they had to be updated externally, but now that Windows is capable of updating the BIOS or the modern UEFI, keep it updated.

It is always best to update the BIOS by following instructions available on your OEM’s website. So make sure you know what you are doing or have someone on your side who can do it for you.

7] Disable Cortana

You can turn off Cortana in Windows 11 or Windows 10 by tweaking the Windows Registry or configuring Group Policy settings. Do that and see if it helps.

Are System Interrupts bad?

No. They are safety measures that are invoked in extreme scenarios, thus preventing any excessive usage of resources. They are also invoked for general purposes, e.g., keystrokes, to read the data without missing anything. The baseline is that System Interrupts happen all the time, and it’s a good thing.

Why is the system interrupts using 100% CPU?

While System interrupts don’t last for long, but if the hardware or associated driver starts misbehaving, and does not respond as expected, then the whole process gets into the loop causing high CPU usage—the only way to resolve this reinstalling the driver or replacing the hardware.

How to make sure CPU usage is controlled?

Apart from using an application that needs more CPU, it is best to keep track of the background processes. These processes usually keep using CPU and spike all of a sudden if they get stuck. So if you don’t want an application to be in the background, make sure to disable it from the startup. And close if you are not using it.
