NoDefender – Disable Windows Defender in Windows 10 with few clicks

RECOMMENDED: Click here to fix Windows errors and optimize system performance

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.

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
    Sample submission windows 10 defender disable options
  5. Now go to the next step in NoDefender. On the Step 2 page, click Disable Windows Defender nodefender 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.

    “Cloud-based Protection”

      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?

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

        Hot debate. What do you think? Thumb up 4 Thumb down 6

          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.

        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 in the ass, next time they’ll think twice before trying to fuck with customers.

    Great idea, but for me, on Build 10130, caused werfault.exe to run and never displays a screen

      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.

          Confirmed that defender WILL NOT restart,
          Are there any ways of getting the service running again?

          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.

            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.

    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.

    How do you reenable? The article says to use the app but there is no option

    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.

      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.

    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.

    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: http://i.imgur.com/QJz6L4H.png

    My Norton anti virus had excluded it that says it is a malware (ws.reputation.1). What you said about?

      The application is clean. Norton Antivirus is fucking 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:

    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?

    Thanks!

    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 :-(

    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 !

    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?

    Thanks!

    Once I have used NoDefender, can I delete it from my computer? Or must it remain to keep Defender from starting again?

    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.

    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

      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)
