The MSE binaries are located in the following folder: C:\Program Files\Microsoft Security Essentials. For years I had used other free Antivirus programs on my home based clients, but have switched them all to MSE since it’s release in September 2009. To access some of its settings (like), you need to navigate to Settings > Update & Security > Windows Security page.Īlthough the native security solution is not as comprehensive as some other third-party antivirus software out there for Windows operating system, it does offer a good basic protection.Microsoft Security Essentials (MSE) is Microsoft’s free Antivirus Software which helps protecting clients against viruses and spyware. Like Security Essentials, it offers real-time protection and uses Windows Update service to automatically download latest definition updates. The Windows Defender in Windows 10 helps users protect their PCs from viruses, malware, and other threats. You can launch Windows Defender by typing the same in Start menu or taskbar search box.

The UI of Windows Defender in Windows 10, as you can see in the above picture, is slightly different from the Security Essentials. Rather, Windows Defender in Windows 10 comprises all the features of Microsoft Security Essentials and this is the reason why Security Essentials is not available for Windows 10. For users coming from Windows 7, the Windows Defender in Windows 10 is not just the Defender of Windows 7. Like its predecessor Windows 8, Windows 10 also ships with Windows Defender (called as Microsoft Defender in the latest version). Windows Defender is Security Essentials in Windows 10
