We all know that Windows 10 is not the most used desktop operating system. Windows has more users than other desktop operating systems like macOS and Linux. Also, the operating system offers more and better features than any other desktop operating system.

Another good thing about Windows 10 is that Microsoft pushes updates regularly to make the OS bug-free and feature-rich. By default, Windows 10 offers you all the essential tools to maintain your privacy and security. If we talk about Security, Microsoft offers you a Windows defender.

What is Windows Defender?

Windows Defender is an antivirus suite that comes built-in with Windows 10. It’s a free utility provided by Microsoft to safeguard your system from security threats. Usually, users don’t need to install any antivirus suite on Windows 10 to protect their computer as Windows Defender can handle almost all significant threats.

However, users might need to use a Windows Defender alternative in some cases. Just like every other security suite, Windows defender also has some drawbacks. The biggest disadvantage of Windows defender is that it slows down your computer. Sometimes Windows defender also triggers BSOD error. Since Windows Defender is provided for free, one can’t expect robust security features from the Windows defender.

What’s worst is that there’s no direct way to disable Windows Defender on Windows 10. If you want to disable the Windows defender, you need to install another security suite. Windows 10 automatically disables the Defender application whenever it finds a new antivirus.
