Editor to share with you how to use commands to update Windows10 antivirus software, I hope you will gain something after reading this article, let's discuss it together!

Windows Defender is now a mature security product because it provides inspection capabilities comparable to those bundled with third-party solutions from the world's leading companies.

In addition, in Win10, Windows Defender is the core part of Windows Security, Windows Security is a central security center, and other tools such as firewall settings, parental controls, etc.

And, because it's already an advanced security application, Windows Defender has almost all the features you want to find in security products today, including real-time scanning, cloud analytics, and even blackmail software protection.

Microsoft releases new virus definitions on a regular basis, so these new virus definitions must be installed as soon as possible to ensure that the latest threats are detected. In any case, this should be done for any antivirus product, because the latest virus definitions help applications detect the latest threats and block them before they reach the data.

On Win10, Windows Defender updates can be done directly through Windows Update and the latest definitions can be installed-because antivirus software is integrated at the OS level, all updates are distributed through Windows Update. So, technically, all you need to do is check the following path for updates on the device running windows 10:

Windows 10 > Settings > updates and Security > Windows updates > check for updates

If there are any new virus definitions, windows 10 should automatically download and install them on your device. To check the updated version of the definition installed on the device, follow the following path:

Windows Security > virus and threat Protection > virus and threat Protection updates > check for updates

However, due to errors or malware infections that prevent you from installing updates to prevent them from being deleted, checking for updates that download new virus definitions does not always work properly. This behavior has been around for a long time, and it has recently been found that exploits based on driver vulnerabilities disable your antivirus software in order to avoid being deleted.

Fortunately, on windows 10 devices, you can also update Windows Defender from the command line utility, which is very useful, especially if you cannot update manually from Windows Update. To do this, you first need to start an elevated command prompt screen, which is an instance of a command prompt with administrator privileges.

To do this, click start menu > Type cmd.exe > right-click the command prompt > run as an administrator.

In the Command prompt window, type the following command to check for new virus definition updates and download, if any:

"% ProgramFiles%\ Windows Defender\ MpCmdRun.exe"-SignatureUpdate

If the process fails for a variety of reasons, it is likely that the definition cache on the device needs to be deleted-which is actually why some updates released through Windows Update for Windows Defender may not be installed. In this case, the following command comes in handy (run it before the above command to update Windows Defender):

"% ProgramFiles%\ Windows Defender\ MpCmdRun.exe"-removedefinitions-dynamicsignatures

After running these commands, there is no need to restart.
