It prevents most viruses and malware from attacking the operating system. However, it can sometimes cause trouble, such as blocking harmless software from being used. Don\u2019t worry, next, we\u2019ll explain how to turn off Windows Defender on different PCs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Windows Defender?<\/h2>\n\n\n\n<p>Windows Defender, also known as <a href=\"https:\/\/www.microsoft.com\/en-us\/windows\/comprehensive-security\" target=\"_blank\" rel=\"noopener nofollow\" title=\"\">Windows Security<\/a>, is a free antivirus and security solution built into Windows computers. It includes various features such as real-time protection (RTP), <a href=\"https:\/\/lightningxvpn.com\/blog\/en\/network-firewall-security\/\" target=\"_blank\" rel=\"noopener\" title=\"\">firewall and network protection<\/a>, ransomware protection, app and browser control, cloud-delivered protection, and more. It is highly compatible with Windows systems and consumes relatively few system resources.<\/p>\n\n\n\n<p>However, compared to some advanced security suites, Windows Defender lacks more advanced and personalized protection settings. Some users think <a href=\"https:\/\/lightningxvpn.com\/blog\/en\/is-windows-defender-enough\/\" target=\"_blank\" rel=\"noopener\" title=\"\">Windows Defender is not enough<\/a> and install third-party antivirus software. However, Windows Defender may mistakenly flag it as a virus, preventing it from being opened.<\/p>\n\n\n\n<p>To fix the problems, you can turn Windows Defender off. Next, we will introduce the most common methods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Temporarily Turn off Windows Defender on Windows 7\/10\/11<\/h2>\n\n\n\n<p>Real-time protection and the firewall are both important consistent of Windows Defender.

However, method 2 is risky because it can expose your PC to viruses and malware.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Way 1. Install a Third-party Antivirus Software to Replace Windows Defender Antivirus<\/h3>\n\n\n\n<p>Windows Defender allows third-party antivirus software to replace it, and they are easier to manage than Windows Defender. However, you should choose reliable brands to protect your computer with robust ability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Way 2. Use the Command Prompt to Turn Windows Defender off<\/h3>\n\n\n\n<p>This method will permanently turn off your Windows Defender and won\u2019t provide any other protection.<\/p>\n\n\n\n<p>1. Turn off Tamper Protection<\/p>\n\n\n\n<ul>\n<li>Open \u201cWindows Security\u201d.<\/li>\n\n\n\n<li>Click \u201cVirus &amp; threat protection\u201d.<\/li>\n\n\n\n<li>Under \u201cVirus &amp; threat protection settings\u201d, click \u201cManage settings\u201d.<\/li>\n\n\n\n<li>Scroll down to find \u201cTamper protection\u201d and switch the toggle off.<\/li>\n<\/ul>\n\n\n\n<p>2. Run a Command in the Command Prompt<\/p>\n\n\n\n<p>Step 1. Press <strong>Win + X<\/strong> and choose \u201cTerminal (Admin)\u201d from the menu.<\/p>\n\n\n\n<p>Step 2. Run the command below in the Command Prompt.<\/p>\n\n\n\n<p><strong>reg add &#8220;HKEY_LOCAL_MACHINE\\SOFTWARE\\Policies\\Microsoft\\Windows Defender&#8221; \/v DisableAntiSpyware \/t REG_DWORD \/d 1 \/f<\/strong><\/p>\n\n\n\n<p>Step 3. After the confirmation message appears, restart your computer to apply the changes.<\/p>\n\n\n\n<p>Now the Windows protection is completely turned off via Command Prompt. To turn it back on, run this command:<\/p>\n\n\n\n<p><strong>reg delete &#8220;HKEY_LOCAL_MACHINE\\SOFTWARE\\Policies\\Microsoft\\Windows Defender&#8221; \/v DisableAntiSpyware \/f<\/strong><\/p>\n\n\n\n<p><strong>Note:<\/strong> You should be careful to run a command in the Command Prompt because a wrong command can lead to data loss.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Benefits and Drawbacks of Turning off Windows Defender<\/h2>\n\n\n\n<p>Though turning off Windows Defender has benefits, it is better to keep it on.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages<\/h3>\n\n\n\n<p><strong>Avoid false positives:<\/strong> Sometimes Windows Defender will falsely detect some software or breaking tools as viruses and block these programs from being used. Turning it off allows you to access them again.<\/p>\n\n\n\n<p><strong>Reduce the occupation of system resources:<\/strong> Windows Defender will occupy CPU and storage in the background. Turning it off might enhance the performance of your computer.<\/p>\n\n\n\n<p><strong>Increase the speed of the file transmission:<\/strong> Before downloading or transferring files, Windows Defender will scan if there\u2019s viruses, which can slow down the file transfer. Turning it off can increase speed.<\/p>\n\n\n\n<p><strong>Avoid conflicts with third-party antivirus:<\/strong> Turning off Windows Defender can prevent conflicts with other third-party antivirus software.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Disadvantages<\/h3>\n\n\n\n<p><strong>The system is easy to attack:<\/strong> Once you turn Windows Defender off, your computer can be easily accessed by viruses and malware.<\/p>\n\n\n\n<p><strong>Your computer can be easily hacked:<\/strong> With Windows Defender turned on, it is hard for hackers to access and control your computer.<\/p>\n\n\n\n<p><strong>Some Windows security features cannot be used:<\/strong> Features such as Windows Defender&#8217;s ransomware protection, cloud scanning, and controlled folder access will be disabled.<\/p>\n\n\n\n<p><strong>Tip:<\/strong> To add a layer of security to your Windows PC, try <a href=\"https:\/\/lightningxvpn.com\/\" target=\"_blank\" rel=\"noopener\" title=\"\">LightningX VPN<\/a>.

You can temporarily disable it by turning off real-time protection or the firewall and network protection. These protections will automatically reactivate once you restart your computer. To permanently disable Windows Defender, you can either install third-party software or execute a specific command in the Command Prompt.<\/p>\n\n\n\n<p>However, we strongly advise against disabling these protections for extended periods.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Windows Defender is a powerful tool for protecting PCs.
