How to Disable Antivirus on Windows 11 Permanently
To turn off antivirus permanently on Windows 11, you must carefully follow certain steps. Here, we show you how to use the Registry Editor and Group Policy Editor. We also cover how to check Microsoft Defender’s status.
Using Registry Editor
If you want to edit registry Windows 11 to stop Microsoft Defender, start in Safe Mode. This ensures changes stick after a restart. Press Win + R, type regedit, and press Enter. Navigate to HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows Defender.
- Create a new DWORD (32-bit) Value called DisableAntiSpyware.
- Set its value to 1 to turn off Microsoft Defender’s antivirus protection.
Restart your PC to make the antivirus deactivation permanent. It’s wise to regularly check afterwards to ensure the settings haven’t changed.
Using Group Policy Editor
Windows 11 Pro users or higher can disable Microsoft Defender through the Group Policy Editor. Press Win + R, enter gpedit.msc, and hit Enter. Go to Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus.
- Find and open the Turn off Microsoft Defender Antivirus policy.
- Choose Enabled and click OK.
Restart your PC to apply these group policy antivirus settings. This method is only for Windows 11 Pro or Enterprise. Windows 11 Home users should use the Registry Editor.
Checking the Status of Microsoft Defender
After turning off the antivirus, make sure it stays off. Open Windows PowerShell or Command Prompt as an admin. Run this command:
Get-MpComputerStatus | select AMRunningMode
This shows Microsoft Defender’s current mode. If it’s off as expected, the output will confirm it’s not running. Keep checking, especially after updates, to keep your settings right.
Replacing Microsoft Defender with a Third-Party Antivirus Solution
Looking to switch from Microsoft Defender to a different antivirus? There are many good third-party antivirus software options. Malwarebytes, Bitdefender, and Webroot are top picks. They are known for their strong security features. When you set them up, they’ll turn off Microsoft Defender’s antivirus. This prevents any problems between the two.
Switching to a new antivirus doesn’t mean losing Microsoft’s malware detection. If you remove the third-party app, Microsoft Defender turns back on. It protects your device right away. This makes changing antiviruses safe, without leaving your computer at risk.
Some prefer using Microsoft Defender for checks now and then, besides their main non-Microsoft antivirus. This double-layer approach increases security. Also, make sure the third-party antivirus software works well with Windows 11. This avoids any troubles or system issues.
On Windows Server, turn off Microsoft Defender Antivirus manually. This is to avoid conflicts, especially on Windows Server 2019, 2016, and 2012 R2. Adjusting the registry for Microsoft Defender to passive mode might be needed. This helps the server run smoothly, without slowing down from using two antiviruses at once.
Whether you like Malwarebytes for its simplicity, Bitdefender’s many features, or Webroot’s cloud-based security, these Microsoft Defender alternatives are solid. They keep your Windows device secure.
Conclusion
Learning to turn off Microsoft Defender in Windows 11 lets users control their antivirus based on their needs. Turning off real-time protection or fully disabling it through the Registry Editor or Group Policy Editor needs care. If you disable Windows Defender for troubleshooting or installing software, remember the risk of leaving your computer open to dangers.
Using a third-party antivirus adds more security. But, understanding how to manage antivirus settings in Windows is key. Turning off important security features, even for a short time, can expose your computer to threats. Keeping your Windows 11 safe means finding the right balance between ease and strong protection.
For expert users, turning off antivirus features might help with certain tasks. But, make sure this is only temporary. Always switch your antivirus back on after you’re done. If you stay careful and focused on protecting your system, you can handle your Windows security wisely without risking your computer’s safety.
