As of today, Windows 10 has officially entered a new phase, marking the end of its non-security support. Users can breathe a sigh of relief, however, as those enrolled in the Extended Security Updates (ESU) program will continue to receive essential security updates for at least another year. This transition means that while the operating system will remain secure for online activities, it will no longer benefit from new features or fixes for existing bugs.
Microsoft Defender will continue to support Windows 10, says Microsoft
In light of these changes, many users are curious about the fate of Microsoft Defender, the built-in antivirus solution. Fortunately, Microsoft has addressed this concern directly on its website, providing clarity and reassurance for Windows 10 users.
According to a recent post on the Microsoft Defender for Endpoint Blog, titled “End of Windows 10 Support: What Defender Customers Need to Know,” Microsoft has confirmed that Defender will continue to offer its detection and protection capabilities for Windows 10 throughout the ESU period. The blog states:
Defender supports a range of legacy systems, including Windows 10. Microsoft Defender will continue to provide detection and protection capabilities to the extent possible on Windows 10 and other legacy systems. Keep in mind that security solutions on legacy systems are inherently less secure and may not be able to receive all new features, so please review the next section for important actions you can take.
For Windows 10 customers without Defender, Microsoft will continue to provide security intelligence updates for the built-in Microsoft Defender Antivirus protection through October 2028. Of course, Defender Antivirus alone isn’t a comprehensive risk mitigation posture without Microsoft Defender detection and response deployed across your digital estate.
This assurance suggests that Microsoft Defender will remain functional on Windows 10 for the duration of the ESU year. While the company has not specified the exact timeline for ongoing support, it is reasonable to anticipate that Defender will be available until the ESU concludes. Given Microsoft’s previous commitment to provide three more years of support for enrolled users, it seems likely that Defender will accompany them throughout this period.
Ultimately, Microsoft recommends that users either continue with Windows 10 under the ESU or consider upgrading to Windows 11. Regardless of the level of support for Microsoft Defender in the coming years, enrolling in the ESU remains a prudent choice to ensure the operating system stays current and secure.
