NoDefender – Disable Windows Defender in Windows 10 with few clicks

Many people complain that Windows 10 forces them to use Windows Defender and that there is no way to disable it. Once you disable it using the Settings, the operating system re-enables it soon. Here is a solution which will allow you to disable Windows Defender in Windows 10 completely.
Update: Some users report that they can't disable Windows Defender with "NoDefender" in Windows 10 Anniversary Update. In this case, you can use Winaero Tweaker to disable Windows Defender:

You can download it here: Download Winaero Tweaker.

Let me introduce you to NoDefender - a small third party app created by my friend Lucas. He coded it to allow anyone to disable Windows Defender in Windows 10 and take back control of the operating system which Microsoft seems to constantly take away from the user.

  1. Download the NoDefender app.
  2. Unpack and run the app
  3. On the Step 1 page, click the Open Windows Defender Settings button.nodefender step 1
  4. This will open the appropriate page of the Settings app. Disable the following options there:
    Real-time protection
    Cloud-based protection

  5. Now go to the next step in NoDefender. On the Step 2 page, click Disable Windows Defendernodefender step 2
  6. Go to the next step.nodefender step 3

You are done. Windows Defender will be disabled in Windows 10. Using NoDefender, you can re-enable it later if you want. That's it.

    1. A lot of anti-viruses use “Cloud-based protection”, I don’t know what it means for Microsoft but in these other products it means that the AV will get the hash of the files and then check it against the “cloud” servers, the upsides to this is that the cloud is always updated with the latest signatures meaning it can detect malware that has not yet been downloaded to the local AV database, but if you use Cloud AV exclusively then you also don’t need a local AV database with signatures, meaning less space.

      The downside with exclusively using Cloud based AV is no detections if you lose internet connection.

      Personally I’m using a product with Cloud AV, that way I don’t have to worry about keeping the AV database updated all the time and I won’t have to worry about AV database updates happening at a bad time when I need all the bandwidth/processing power for other things.

      Again I’m not sure what Microsoft means by it though, of course I’d agree that “Cloud” is a buzzword, but it does sound better than “Server-based protection” no?

      1. “Cloud” is less a buzzword and more an easy-to-remember name for “dynamic VPS” (VPS = virtual private server).

        1. Online, it was it used to be called. Of course it is on a server and only tools call it the cloud. It is the internet.

      2. Where’s the need to detect viruses if your Internet is down anyway?
        Windows Defender is just absolute trash, if I bought a software why am I not able to have full control over it? That’s why I cracked Windows 10 and Microsoft can take it [censored], next time they’ll think twice before trying to [censored] with customers.

    2. I can't download NoDefender 15 August 2020 , it diverts to some stupid clickbait news maybe Win 10 security says:

      I can’t download NoDefender as of 15 August 2020 , it diverts to some stupid clickbait news maybe Win 10 security has blocked it , all sorts of weird things are happenining since I upgraded to 10 from 7 , even switching off while posting community standards politically sensitive memes thnks to the intel backdoor ‘management’ system grrrr

      1. is there some other link that is reliable for NoDefender ? as I can’t get it to download from this page ,, it must work ! lol …… I have downloaded other apps no problems from your site , but they haven’t been able to solve or stop the MsMpEng.exe service or the associated AntiMalware Service Executable process even though the Defender registry keys have been permanently modified ? any clues would be greatly appreciated . Cheers

  1. Actually, I’m running Build 10130 in Vbox and that might be the problem:

    1. Open Nodefender, at the step 1, click open windows defender settings, then scroll down to the bottom, hit the line “Use Windows defender”. That’s all.
      #Sorry my English is not very good.

        1. All the complaining about not being able to re-enable, I don’t get. If you read all the posts, it is outlined and it is easy and it works.

          In the first box after opening No Defender, click where it takes you to Defender Settings.
          Scroll to bottom of settings
          Click “Use Windows Defender”

          And, it’s back.

          So, I will run the No Defender Again. I Just wish it would stay away. It came back all on its own. I am furious. I hate Defender. I hate Edge. I hate Bing. Those are the kinds of computing suited for the Facebook crowd.

          1. I’m not sure if it’s a Home/Pro issue or something to do with an update, but I don’t see “Use Windows Defender” at the bottom after disabling it. What’s there is “Open Windows Defender”, and upon clicking that I get:

            This application has been turned off and isn’t monitoring your computer.
            If you’re using another app to check for malicious or unwanted software, use Security and Maintenance to check that app’s status.

            So … the OP’s complaint was valid. However, I could solve it by, as the message says, going into Security and Maintenance via Control Panel and enabling Defender there.

  2. App works great, thank you. The only other option I found that works is to boot the machine into Linux (I dual boot Windows 10 and Linux Mint), and rename the Windows Defender folder, effectively preventing it from recognizing and running the program at startup.

    1. Good question, I’d also would know how to reenable WD. Options which could do that became grey and can’t be changed. Thank you.

  3. Cheers! All that needs to be changed now is hosting your encryption key in OneDrive. Oh well, at least a local account fixes that one.

    1. OK make a system restore before you do this. I’m not sure why this is happening, but disabling Windows Defender somehow doesn’t stop it from quarantining files afterwards.

  4. After using this program, Defender _service_ returns back after some time passed while the program itself stays still disabled. Currently I try to disable it via gpedit.msc too hoping it helps.

  5. The program does not allow you to re-enable? Are there any other ways of doing so? I get a popup saying the Windows defender app has been turned off:

    thanks for the help :)

    1. The application is clean. Norton Antivirus is [censored]ing shit.
      Especially its “reputation” system. It says “malware” even about my AeroRainbow freeware, which does nothing except changing colors of the window frame.
      Add the file to exclusion.
      Alternatively, you might be interesting in disabling defender without third party apps but with Group Policy as mentioned here:

  6. I’m using the NoDefender app and while it opens the Defender tab in the Settings window, Windows won’t allow me to turn off Defender (the toggles are the “dead” grey, not the “live” black). Any thoughts/ideas/suggestions?


      1. I’m not sure what that means or how I would find that information. I’m working on a fresh out of the box Dell that just updated to Windows 10, if that helps…

  7. Running Windows 10 Pro with latest updates as of 8/15 (last one was KB3081438). Defender gets disabled initially and when I try to run I even get a message to that effect “This app has been turned off and isn’t monitoring your computer”. Unfortunately after a while it turns itself back on. The irony is that Defender acts just like the malware it’s trying to protect us from :-(

  8. Wow the no defender app seems to work
    my windows defender is now not activate able and its kind of blank
    thank you so much!

  9. Windows defender is disabled but not the quarantine. It’s really annoying because it blocks some of my programms and I can’t access the quarantine anymore as I can’t reactivate defender. Please help me !

  10. Can someone please help. I used NoDefender to temporarily disable defender and now want to turn it back on. There is no option in the app to re-enable defender, and I tried removing the disable defender registry key, nothing works. Have not installed another anti-virus app either. Can someone help me re-enable defender?


  11. App worked great but I cannot turn defender back on, when I try I get an error message that says “If you are using another app please turn off that app”

    1. same here, i keep getting errors when i try to get a windows update and i want to turn defender back on to see if it fixes the situation, and it won’t go back on.

  12. Many thanks for this tool, Sergey.!rVVCQZAK!XF-sdyGrKsubgcixLt5AUT8x-oPzY41KAGC3z6QV4IQ worked well.

  13. Seriously… Do not use this app. I thought it would be cool to use it, as it says it can re-enable it, but it does not give me the option. I don’t exactly know what it did, but I want to reverse it. You can clearly see many people asking for help, and nobody is getting any. Over the course of a few months, and nobody is getting any help. This is crap and I am pissed.

  14. Download link is currently broken (at the time of this post).

    For people that are trying to re-enable windows defender what you can do is:
    1. Open up control panel (search it up using win + Q)
    2. View items by small/large items (top right option)
    3. Scroll down to Security and Maintenance
    4. Under security there should be a option to turn on windows defender

    1. I get to the point where you described, but there is no option to turn it back on.
      Every space is taken by Kaspersky.
      It’s not that i badly need Win Defender back, but would be nice to know a way.
      (If it will re-enable autmatically i won’t be that mad lol)

  15. Hey it work on getting the window defender to off. the sample is still working. I will try again to stop the sampling going.Thank you.

  16. the sampling is still on while others are off? MMMM something wrong? Please send fix to slight error. Thank you.

  17. I’ll keep saying this over and over: antivirus is more harmful than any virus ever created after 1999 – 2000.

    1. Which disc? Can you provide more details so I can ask the author or point him to your comment?

      1. My USB ports stopped functioning after using this program.
        I can not start my mobile internet connection, which is loaded from a USB stick modem.
        I bought a new USB-modem, and it can’t even install the hardware form the new modem.
        (I wrote this message from a friends computer.)

        1. Here is the author’s reply:

          There’s no part of code that would interacting with disks or drives, only thing it does is disable Defender things in registry

  18. At this point it’s very clear that windows defender is an MS programed virus placed on your PC to take control at random. If you or I did this we would be called hackers and be in jail.. Gonna have to wipe out some registers to rid myself of this nasty MS Virus!

  19. After reading quite a few of your comments I think its best left alone I don’t really like Defender but trying
    to disable it seems to me a really hit and miss thing. Waste of ones time

    1. I successfully disabled it with Group Policy tweak via Winaero Tweaker.
      It works like a charm, the app does not re-enable itself.

  20. Be careful with running compiled, closed source applications. Maybe the author can refer to a revertable open-source solution like ?
