By now, you likely have upgraded your Windows 7 installation to Windows 10 by using the free upgrade offer from Microsoft and probably wondering why Microsoft Security Essentials is not available for Windows 10.
Microsoft Security Essentials program doesn’t support Windows 10, meaning that you can’t install Security Essentials in Windows 10. In fact, it doesn’t even support the previously released Windows 8/8.1 as well.
When you upgraded your Windows 7 installation to Windows 10, the program was removed because Windows 10 ships with a good antimalware program out of the box.
Windows Defender is Security Essentials in Windows 10
Like its predecessor Windows 8, Windows 10 also ships with Windows Defender. For users coming from Windows 7, the Windows Defender in Windows 10 is not just the Defender of Windows 7. 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.
The UI of Windows Defender in Windows 10, as you can see in the above picture, looks more or less like the Security Essentials. You can launch Windows Defender by typing the same in Start menu or taskbar search box.
The Windows Defender in Windows 10 helps users protect their PCs from viruses, malware, and other threats. Like Security Essentials, it offers real-time protection and uses Windows Update service to automatically download latest definition updates.
To access some of its settings (like), you need to navigate to the Security section of Settings app.
Although the native security solution is not as powerful as some other third-party antivirus software out there for Windows operating system, it does offer good basic protection.
Finally, if you aren’t satisfied with Windows Defender in Windows 10 and would like to use a third-party antivirus program instead, use free programs like Avast Free Antivirus.
