Like its predecessor, the latest Windows 10 also ships with the Windows Defender program. Windows Defender is designed to help protect your PC from viruses, malware, and other threats. While it might not offer all the features available in third-party antivirus software like Avast Free for Windows 10, it’s adequate for most home users.
That said, you might want to protect your Windows 10 PC better using better third-party antivirus software. Since installing two or more antivirus on the same PC is not recommended, it’s a good idea to disable Microsoft’s Windows Defender before installing third-party antivirus software. Indeed, most antivirus software will automatically disable Windows Defender during the installation, some antivirus programs ask the user to turn off or disable Windows Defender in Windows 10 manually.
In the previous Windows version, turning off or disabling Windows Defender was easy. There was an option under Windows Defender Settings to turn on or off the defender. In Windows 10, Microsoft has moved Windows Defender settings to the Settings app.
Completely disable Windows Defender in Windows 10
While there is an option to turn off real-time protection of Windows Defender, there is no option to turn off Windows Defender completely. If Windows 10 finds that real-time protection is turned off for a while, real-time protection will be turned on automatically.
To disable Windows Defender permanently in Windows 10, we need to manually disable Windows Defender service and stop the same from starting automatically. As most users don’t prefer manually changing default settings of services, here is a small tool designed to enable you to turn off or disable Windows Defender in Windows 10 completely.

Finally, turn off the tamper protection toggle switch.
