Note

For a list of recent security intelligence updates, see Antimalware updates change log - Microsoft Security Intelligence.

Engine updates are included with security intelligence updates and are released on a monthly cadence.

Microsoft Defender Antivirus platform support

Platform and engine updates are provided on a monthly cadence. To be fully supported, keep current with the latest platform updates. Our support structure is dynamic, evolving into two phases depending on the availability of the latest platform version:

• Security and Critical Updates servicing phase - When running the latest platform version, you will be eligible to receive both Security and Critical updates to the anti-malware platform.

• Technical Support (Only) phase - After a new platform version is released, support for older versions (N-2) will reduce to technical support only. Platform versions older than N-2 will no longer be supported.*

* Technical support will continue to be provided for upgrades from the Windows 10 release version (see Platform version included with Windows 10 releases) to the latest platform version.

Windows Defender Blocking Internet

During the technical support (only) phase, commercially reasonable support incidents will be provided through Microsoft Customer Service & Support and Microsoft’s managed support offerings (such as Premier Support). If a support incident requires escalation to development for further guidance, requires a non-security update, or requires a security update, customers will be asked to upgrade to the latest platform version or an intermediate update (*).

Platform version included with Windows 10 releases

The below table provides the Microsoft Defender Antivirus platform and engine versions that are shipped with the latest Windows 10 releases:

For Windows 10 release information, see the Windows lifecycle fact sheet.

Updates for Deployment Image Servicing and Management (DISM)

We recommend updating your Windows 10 (Enterprise, Pro, and Home editions), Windows Server 2019, and Windows Server 2016 OS installation images with the latest antivirus and antimalware updates. Keeping your OS installation images up to date helps avoid a gap in protection.
