Windows 10: System interrupts

So its this app called "System interrupts" eats my CPU. I saw a lot of tutorials how to fix but I don't understand why does its CPU usage fall after I open task manager? Is windows trying to hide it from me? Why does the host calles "Windows update" eat so much disk? I have all the updates installed.

System Interrupts - Problem or Symptom?

1 If your computer is still supported by its maker, are there any BIOS updates available? They can have significant effects on hardware.

2 Do bear in mind that the excessive** system interrupts problem might be caused by a misbehaving driver rather than an outdated driver. Checking for updates will have no effect in such cases but reinstalling existing drivers might. At the very least, I would suggest reinstalling each third-party driver just to eliminate driver faults as a cause.

3 I agree that stating your system specs could help. If other users recognise particular hardware that causes problems they might be able to suggest solutions or workarounds.

4 Do you have any particularly old hardware that might finally have been rendered fully or partially incompatible with the latest Windows updates?

5 Do have a look at the discussions I linked you to because one of them might help in isolating the cause of the problem.

6 What changes preceded the onset of the problem?

[** System interrupts are normal & they are essential. System interrupts that cause slow system performance by loading its resources are 'excessive' and it is those that my comments refer to.]

Receiving errors, System interrupts Deferred procedure calls and interrupt service routines

Hi,

Thank you for posting your query on Microsoft Community.

I appreciate if you could answer a few questions to narrow down to the issue.

• 
  What is the make and model of the computer?
  
• 
  When exactly you received this error?
  
• 
  Did you make any recent changes to the computer?
  
• 
  Which connection are you using to access internet? Wired or wireless connection?
  
• 
  Did you install any third party security application?
  

A deferred procedure call is an interrupt-handling mechanism in the Windows operating system where the drivers can reference when running certain processes. Deferred procedure call allows a task to be activated but not executed, from a highly prioritized
interrupt request level (IRQL).

As an initial troubleshooting step, I suggest you to put the computer in Safe mode and check if you receive this error.

System Interrupts - Problem or Symptom?

You are right, disabling the network kills the "interrupt" (don't know what to do with it though!).

Edit: this might be the answer networking - High System CPU and interrupts when network I/O - Super User (a feature that downloads and shares updates on network from my PC is enabled)
