Yes, Windows Defender is enabled in Windows by default. Windows Defender is a built-in security program that helps protect your computer from viruses, spyware, and other malicious software.
When you first install Windows, it automatically configures Windows Defender to be enabled. As part of the installation process, Windows downloads the latest virus definitions from the Microsoft Update website, which it then uses to scan your system for potential security threats.
When you first turn your computer on, Windows will check for available updates, including any new Windows Defender definitions. If it finds any, it will download them and let you know when they’re ready to be installed. Once installed, Windows Defender is ready to start protecting your PC against any security threats it finds.
Windows Defender runs in the background to help keep your computer secure. It continually monitors your computer’s activities and scans files whenever they are accessed or modified. It performs regular scans to detect any new security threats that may have been added since the last scan. You can view a detailed report of the results of each scan in the Windows Defender History window.
You can also manually configure Windows Defender to scan your system on a regular basis. To do this, open the Windows Defender Security Center from the Start menu, then click on “Schedule Scan”. From here you can set up a schedule for daily, weekly, or monthly scans.
In addition to running scans, Windows Defender also blocks known malicious programs from running on your system. When a program is blocked, Windows Defender will display an alert to let you know. If you find the program to be legitimate, you can unblock it, which will allow the program to run again normally.
In short, Windows Defender is automatically enabled on all Windows systems. It works in the background to help protect your computer from security threats such as viruses, malware, and spyware. You can also manually configure it to run regular scans and block known malicious programs.
