Windows Defender can Significantly Impact Intel CPU Performance, We have the Fix

Veseleil · Jun 1, 2023

"Completely remove the software and all associated files, folders, and registry items." the best solution indeed.

Nah it doesn't delete - it quarantines them. You can do two clicks and get them back and excluded from future scans (It doesnt like a few of my router hacking tools, but it's also clear that they're "Hack Tools" and potentially unwanted)

When you compare the results instead of techspots view on them, it's not quite what they make you think
Equal best protection, equal best usability, 5.0 of 6.0 for performance

The ones they recommend like Avast have constant popups peddling addons and upgrades, so i'm not sure how that's got better usability

Their forums had the best answer on this one (Still an issue now, older post was just the funniest and first hit)

With Avast, I do custom installation with only the needed components installed. I don't get any of those crapware that you mentioned. Then, I also set it to "Game Mode". With this setting, I don't get nagged. Works pretty well.

That's just the thing, when you install the bare minimum, it nags you about some other stuff you "should" install. Complete with the usual "we have detected X on your system, but if you install Y from us, it will take care of it for you".

Not that I've seen. The diferences are in the edition of Windows being used. Home deletes without prompting. Pro handles things depending on user configuration.

Considering the target audience, that's probably the right thing to do. Annoying as hell for those of us that know how to use a computer.

I was just poking at users that just click "next", "next", "next" and then they're like "umm... I didn't do anything".

Technically, if you can determine that a file contains a virus that has already wiped some of the data/code in the file, you can't recover that. It's ok to just delete it. But first you'd have to determine that with a (very) high degree of confidence.

Still as a tech always gain consent to do so, trust me. Right it may be, but you don't want an angry customer, even if it's an irrationally angry one.

As someone else pointed out in those links/threads, it begins to spam you once it does scans, or detects certain types of activity. Can take a bit before it begins the nagging and it's extremely offputting.

I've never seen that - it moves them to quarantine to stop them being able to trash your PC while it waits for a user to click something, but it's never, ever deleted them outright.
Googling this shows it to have been the default back in windows 10 as well unless a group policy was set.

They'd never have gotten away with deleting false positives without a massive backlash

And then this:

So it may delete if its a KNOWN virus, while PUP's and 'tools' are quarantined

See this is the problem with microsoft's nonsense, their variable policies cause so much uncertainty and confusion. This is a perfect example of why I don't bother messing with it at all. It get's deleted and replaced by something that works the way it's supposed to. I have better things to do with my time than to sort through microsoft's incompetent BS.

I dont see how its variable?

Delete if known 100% to be malware, quarantine if it's in a grey area
(Where it'd be bad in a work/business environment, but a home user can over-ride if they did want it)

As an example, keygens and eth mining tools end up in that second category - they dont go overboard and delete a keygen just because its for microsoft products, for example.

I dont see how it's possible for any AV to NOT delete known viruses immediately... what else are you expecting?

How do you not? They change there minds more often than most people buy new pants. The decision makers at microsoft frequently go in circles on policies, sometimes as frequently as in-between updates.

USER PROMPTING and complete information WITHOUT the fear-tactic wording.

As someone using the AV, i'm not getting that experience in the slightest.
I'm not seeing it change behaviour, it's consistent.

Confirmed known dangerous active viruses are instantly deleted, anything potentially wanted is quarantined - and you get a popup telling you and offering you a choice of what you want to do

You're talking about things without explaining what you even mean... i'm not seeing these changes. I showed a link from a few years back with windows 10 showing its the same as now in 11.

You don't install and reinstall various versions and editions of Windows on a daily basis. I do. Try it sometime, you'll figure out what I'm talking about fairly quickly.

Both can't be true at the same time. I get what you mean, but poor wording

Not only has this issue not been fixed by Microsoft, the same reduced performance problem is happening on Intel's 12th Gen CPUs. When this issue first surfaced last year, Windows Defender was not running its secret and probably broken code on 12th Gen and newer Intel CPUs. Now it is.

Strange throttling on desktop 12700k fixed with ThrottleStop

I have a system with the 12700k and the MSI PRO Z690-A (ddr5 version) and I'm experiencing a strange throttling behavior or as some would call it clock stretching. I have tried all troubleshooting steps I can think of and those that MSI support could think of. By chance I found that having MSI...

If you have a 12th or 13th Gen CPU, try running the Counter Control program. Usually about 5 minutes after booting up, part of Windows Defender will start up doing something important.

Can i use ThrottleStop on a Desktop-PC? I do not have a laptop or notebook but i would like to have the performance boost for Windows Defender but i dont want to change anything else.

I downloaded the software and started it and i can see that "BD PROCHOT", "SpeedStep" and "C1E" are enabled by default. I just want to get the performance boost for Windows Defender and keep everything else on the default settings and default behaviour like it would be without ThrottleStop. What settings would you recommend in this case or should i not use ThottleStop on a desktop at all ?

Kind regards

I use ThrottleStop on my desktop computer everyday. As long as your computer has an Intel CPU that was released during the last 15 or so years, ThrottleStop should work fine. What CPU does your computer have?

Post some ThrottleStop screenshots if you need help.

Thank you. I have a Intel i7 6700k (Skylake) in my desktop. Yes, so i have a few questions regarding these 3 options that are enabled by default and my question is somewhat tricky to explain.

- BD PROCHOT
- SpeedStep
- C1E

In your guide it says "On older CPUs (pre-Skylake), toggles the software-level governance of CPU clockspeeds". Does that mean this option has no effect at all in my case since i have a Skylake CPU ?

The option BD PROCHOT sounds like it is not necessary on a Desktop with a GPU & CPU that have good cooling. BUT if this is a default Windows feature that is enabled by default anyways, regardless of whether ThrottleStop was ever started or not, then I could also leave it on since it doesnt change the default behaviour of my computer which is exactly what i want. Or is this a features that come with ThrottleStop. It sounds like a laptop feature or is this a general Windows thing that also applies to desktops ?

By default (without using ThrottleStop at all) my CPU clock is always changing between 0.80 and 4.00Ghz most of the time depending on what i am doing. Is this behaviour called "C1E" or is this something else that comes with ThrottleStop ? The reason im asking is i am curious what changes the application exactly makes to my computer as soon as i start the app. Because all i want is the Windows Defender Boost and everything else should behave in the same way it would without using ThrottleStop. But since there are these 3 options that are enabled by default i thought they maybe change the default behaviour of my computer. Thanks in advance for the help.

Kind regards

If microsoft ever officially addressed it, they did so quietly. It seems to have been fixed so it's a non-issue currently as long as you're up to date.

This issue was not fixed. I have heard from users that have told me it also happens to the 12th Gen and newer processors. This issue was swept under the carpet.
