Microsoft Defender to Support Windows 10 Until 2028

17 Oct 2025

Microsoft has announced that its Defender antivirus software will continue providing security updates for Windows 10 PCs until October 2028. This ensures ongoing protection against known and emerging malware threats but excludes new feature updates and general bug fixes for the OS.

Security Support Timeline

Windows 10 users can rely on regular security updates from Microsoft Defender through 2028. Both personal PCs running Microsoft Defender Antivirus and enterprise systems with Defender for Endpoint are covered, the latter extending to previous versions like Windows 8.1, Windows 7 Pro, and Enterprise with SP1.

  • Microsoft Defender Antivirus continues for Windows 10 until 2028.
  • Defender for Endpoint supports earlier Windows versions.
  • No new OS features or bug fixes for Windows 10 will occur.

Upgrade Recommendations and Options

Microsoft recommends upgrading to Windows 11 for access to ongoing bug fixes and new features not available to Windows 10 users. For those unable to upgrade, the company suggests considering its Extended Security Updates (ESU) program, which offers critical updates beyond the standard support window. Enterprise users can purchase ESU for up to three years, and home users have options like redeeming Microsoft Rewards points or direct payment, reportedly $30.

  • Upgrade to Windows 11 for full support.
  • Home users may access ESU through various options.
  • Enterprise can purchase ESU or use Windows 365.
