Microsoft Defender update for Windows operating system installation images

Summary

The first hours of a newly installed Windows deployment can leave the system vulnerable because of a Microsoft Defender protection gap. This is because the OS installation images may contain outdated antimalware software binaries.

The devices on which these deployments are made are inadequately protected until they receive the first antimalware software update. We recommend that you regularly service OS installation images in order to update Microsoft Defender binaries and minimize this protection gap in new deployments.

This article describes antimalware update package for Microsoft Defender in the OS installation images (WIM and VHD files). This feature supports the following OS installation images:

Windows 10 (Enterprise, Pro, and Home editions)

Windows Server 2019

changelog

Install the latest Windows Defender definition updates and make sure your computer is safe from viruses, spyware and other malware at all times

Running any signature-based antivirus without the latest definitions might lead to serious security-related problems. Unless the latest virus definitions are installed, the anti-malware tool might fail in detecting some recent threats, which could lead to data theft and a compromised system.

If you rely on Windows Defender to protect your computer against malware, it is advisable you run definition update on a daily basis. However, there are situations when this is not possible, such as when the PC is no longer connected to the Internet or when you haven’t been around to turn the computer on for a longer period of time.

Ultimately, Windows Defender might fail to update the definitions itself for whatever reason. In such cases you must either force a definition update by navigating to the designated tab of Windows Defender or by downloading and installing the latest signature definitions.

The Windows Defender Definition Updates are offline packages containing the most recent antivirus signature for Windows Defender. Once installed, they will make sure your PC is safe from the latest known viruses, spyware, PUPs, and malicious files.

It is very important that you download and install the 32-bit release for x86 systems and the 64-bit release for x64 systems. Furthermore, please pay attention to the download links, since they are designed for different Windows iterations. Other than that, deployment is fast, so you will have your Windows Defender updated in minutes.
