Coming back to this 7 months later, thank you John!!

John I just wanted to say thank you! I remember that you are one of the first YouTubers that educates with cybersecurity. You are a true talent and very underated.

[ForikiTheRat]

disabling defender is really useful especially when having gaming vms
or vms that you just want to speed up

[sanzj.s]

Worked, idle ram usage from 35% to 23%. Thanks

There are a few caveats to this process depending on how much your organization has done to harden Defender with higher tiers of Microsoft Security licensing, UAC, and so on. Happy to answer questions on specifics in these scenarios.

As a car locksmith i use a lot of tools to edit EEPROM or Flash files.
Al tho'se software are labeled as trojans or virusses wich are not. So to tuning off the defender is realy handy to me.
Also from the Netherlands ;-)

For those of you that don't know how to undo what you did. If you read the description there's a link at the very top where you can see his text write up and you can undo everything you did...

Cool stuff! As I already said in previous comments, I have Real Time and Cloud Protection disabled. The reason is that sometimes the process has some memory leaks. It eats 100% of my 32Gigs and I need the machine to be snappy. But if you're not having these issues or you're not finding yourself in one of the use cases John enumerated, DON'T DISABLE YOUR WINDOWS DEFENDER.

Thanks a lot!
*Quick note:* the first method kills the effectiveness of WDef, but still allows it to run as a background app (which can take up to 5% of your RAM, and that's why I came here lol). So if you don't want WDef's processes to run at all, you should do the changes in the registery editor as explained in part 2 of the vid, and then you'll get rid of these processes running.

This was a very helpful guide to kill defender. In my case I have an industrial CNC controller that runs on Windows. Not common I know, but the #1 best thing you can do is permanently stop everything running in the background possible. Since once it is set up there is no connection to the internet, I'd even like to permanently kill the firewall. Anything to improve latency and responsiveness.

I wonder what happens once a Windows update occurs. Is Microsoft going to try to turn it back on? (Merely disabling the service is pretty easy to reverse, after all.)

[GaurangTandon]

What do the registry values that we changed do? Is it like permission numbers in Linux?

[adityapratap]

I always look forward to your videos John.. haven’t come across any other cybersecurity professional who can be compared to you. Thank you for all the knowledge you share..

I am new to this field, currently working as a sysadmin at a MNC and sponging all the knowledge how much ever I can to excel in it.

God bless you with success prosperity and health!

Thank you again :)
Your big fan!

[KyserClark]

Thank you so much for this video. A very easy to follow method on how to disable Windows Defender. Now I can test the malware I'm trying to make on my Windows 11 VM!

[jruok]

John is so good. All around. I cannot.

[EricRemy]

I can't download anything from the internet now says virus failed to scan

[forxstsombodi]

A nice follow up to yesterday's video

[mysticnate]

its not allowing me to edit when i try to edit Security in platform properties

[hugoflorez]

Jhon thank you very much bro, you are the only one to come with the real solution to this issue

[teddym]

I'd all but given up trying to turn defender periodic scanning off since I use Kaspersky. It re-enables every boot, I have disabled tamper protection and also disabled defender antivirus via gpedit but if I close gp edit and re open it, that disable config is instantly back to the default of "not configured" LOL. And the anti malware executable is always running.
Latest Win 11 Pro, all up to date.
So I will definitely give this a go. I use Emergency Kit as my secondary scanner, manually, once a week. I do not need Defender scanning in the background automatically when it feels like it.
