Windows Defender is the built-in antivirus protection in Windows and is designed to keep your PC safe from malicious software, including viruses, spyware, ransomware, and other malicious programs. To ensure your safety, Windows Defender is automatically updated to provide the latest protection against new security threats.
Windows Defender automatically updates itself through Windows Update, which is a Windows feature that installs important updates that are released by Microsoft. These updates are released on a regular basis and can be downloaded either manually or automatically.
If you have configured Windows Update to download and install automatically, then Windows Defender will be updated automatically as well. If Windows Update has been configured to only download updates but not install them automatically, then the user must manually choose to install the updates that are available.
However, it is important to note that Windows Defender cannot update itself if Windows Update is disabled or not configured correctly. Therefore, it is recommended to configure Windows Update to download and install updates automatically to ensure that your system remains secure.
In addition, Windows Defender also provides an option to check for updates manually. You can access this feature from the Windows Security Center by clicking on the “Update” button. This will bring up a list of available updates that can be installed manually or scheduled for installation at a later time.
It is important to keep Windows Defender updated as new threats are released on a daily basis. By keeping your system current with the latest security updates, you can ensure that your device is protected against the latest threats.
Overall, Windows Defender is designed to keep your PC safe from malicious software. It provides an easy way to keep your system protected by automatically downloading and installing the latest security updates. In addition, you can manually check for updates if needed.
