Problems with latency (Audio-laptop)

How can I do this? (How to disable Real time scanning...). I am glad that there is a possibility to get rid off latency problems offline in concert situations. But I agree it is not the best to switch the defender off.

In WD control panel, you can disable scanning of certain folders, executables and processes. It's tricky to find.

I'll post the path once I get to my computer...

Is it an alternative to use Avast Antivir (seems to be the best free and lightwight antivir program) and switch off the defender permanently?

This may or may not solve the problem. Try fixing Defender first.

This would be fine. I searched for Windows Defender problems in the internet. But it seems not so easy to handle them.

A short addition. I just tested the amounts of latency concerning the Windows protection.
Biggest amount:
Firewall/Network: Public Network
Virus-protection: Real time protection

A lesser amount:
Firewall/Network: Private Network

yeah, real time protection is something you have to work on for those processes that is using audio.

Any ideas, how to do this?

1. Open up Windows security.
2. Go to Virus and Threat protection
3. Go to Virus and Threat protection Settings --> Manage Settings
4. Scroll down to bottom and click Add remove Exclusions
5. Say yes on UAC prompt
6. Add exclusion for each process you find in task manager that is related to audio
7. You can also exclude specific folders if they are written to often to speed up such stuff (I use this for folders I compile code in)

Expect a bit of trial and error here. It takes time to figure out what helps and what not. What does not affect performance should be scanned normally.

I switched off the public-network-firewall (cause it makes also latency-problems). I tried to make exclusions (see exclusion at the attachment), but there are still problems. :-(
Once again a latency report of drivers and processes... Thanks for your patience.

P. S.: When switching off the realtime processes, there are still latency problems with the firewall (public networks). Do you have an idea what to do with that?

(Perhaps, I should try Avast. Is it possible to switch off the defender with all of his functions? Otherwise, there could be conflicts between defender and Avast).

Don't turn off firewall. Public network has nothing to do with your audio stuff.

But it causes latencies when switching realtime scanning and private network firewall off. Or could it be an accident? (Switching Windows firewall and realtime scanning completely off, there is no latency.) I tried the one factor changing system to find the cause for latencies.

Often "hard pagefault" calls "State Repository Service" , but this service cannot be disabled.

I'm wondering if it makes sense to change the value of Win32PrioritySeparation?

Hey folks, thanks for your help, but I give up.
As result of the conversation, I will switch off the Windows defender and realtime protection when being offline.
Then, I can minimize the latency problems.

This is a very big topic.
For example, you can see here

https://docs.google.com/document/d/1c2-lUJq74wuYK1WrA_bIvgb89dUN0sj8-hO3vqmrau4/edit?pli=1

(I hardly ever use it).

TL;DR
On a laptop, you can only install lower latency RAM and data storage.
You need to buy a low-latency laptop right away.

I use my laptop for audio purposes. For some time now, I've been experiencing minor issues with latency and dropouts (see Latency Monitor: screenshot and report attached).The status report indicates the ACPI driver as main problem (also, wdf01000 seems to cause higher latencies at times). I've optimized the laptop for audio using several websites (e.g., optimized power options, changed BIOS settings, although I haven't performed a BIOS update in the last year - I also don't remember exactly how to do it).
Specs:
Win 11 (Version 22H2, Build 22621.2715)
Hardware: Latitude E5570, Dell Inc.
CPU: GenuineIntel Intel(R) Core(TM) i5-6300HQ CPU @ 2.30GHz
Logical processors: 4
Processor groups: 1
RAM:16275 MB total
I use Windows Defender

sorry for bringing this old thread back, but I'm afraid that this Dell Latitude E5570 laptop does not officially support Windows 11 as Dell does not provide any Win11 specific drivers for it, hence this notice from the Dell support site, regarding this laptop pc:

The Microsoft requirements for Windows 11 are not supported on this device. Read more about system requirements here.

OP will need to buy a new laptop that officially supports Windows 11 as running Win11 on an old machine that isn't supported can lead to such latency problems
