Windows 10: DPC and NDIS.sys issue.

Hi,I use an acer Aspire 3 laptop with an intel core i7 and run-on windows 10.I ran a test on LatencyMon as I has having issues when recording music on my laptop. The results said I had a big DPC count/ issue and there was especially an issue with my NDIS.sys. I have reinstalled/updated drivers for audio but there has been no improvement. I have no idea how to solve this issue and really need to record these songs so any help would be much appreciated. Thank you.

:)

 

Windows 10 DPC latency issue with ndis & tcpip.sys

I've been fighting this DPC issues for years and doing a google search for something regarding DPC, but I found a simple fix. The problem was when I installed AVG. DPC didn't start right away (it took months) then I started doing all the disable this and
that and no solution. So, I decided to start tracking down programs (applications/software) and AVG was one of the programs that would cause DPC issues.

I found a website regarding NDIS DPC issues with antiviruses with firewalls. First I tried disabling Web protection and Firewall and restarted and it lasted a week (normally 3 days) before DPC started. I went back to the site and found a solution that fixed
my problem, it told me this,

Press Windows+R.

Typed NCPA.CPL

Right click on your ethernet and clicked Properties

Untick AVG network filter driver

Clicked OK

Restart

2 weeks late, no issues. 0.

I re-enabled web protection and firewall and still no issues.

 

Windows 10 DPC latency issue with ndis & tcpip.sys

Your code and my recent
CrazyPingTest3 trigger DPC latency issue of tcpip.sys after a couple of runs. Like you said.

One run of your code, one run of CrazyPingTest3 or infinite run of my infinite pings (original
CrazyPingTest) cause just 0.5 to 1 ms latency.

But! If I add a 50 ms sleep before starting a new thread, there is no latency at all. See my
CrazyPingTest3). There is a commented line.

And if I add Thread.Sleep(50); before your

p.SendAsync(ip, 1000, ip);

I see no DPC latency too.

And thank you for the link!

Upd. Oh, I was wrong. I made some more runs and had a DPC latency.

And I’m here because of “windows 10 ndis high dpc” issue too.

 

Wdf01000.sys causing DPC and audio is cracking

Is it possible that my internet provider to be causing the high DPC? Because I switched to a different provider some time around the issue started to occur? NDIS suddenly has high again. https://i.imgur.com/WNMrY4C.png
