Microsoft Shifts Defender EDR Updates to Microsoft Update Service

• •Microsoft Defender EDR updates are now delivered via Microsoft Update instead of Patch Tuesday.
• •The change allows for faster deployment of security enhancements and fixes.
• •Organizations must ensure Microsoft Update is enabled for seamless updates.

Microsoft has announced a significant change in how it delivers security updates for Microsoft Defender for Endpoint's EDR capabilities. Starting from June 2026, these updates will no longer be bundled with the monthly Patch Tuesday releases but will instead be delivered through the Microsoft Update service. This change aims to allow for faster deployment of security enhancements without waiting for the standard monthly update cycle. The rollout began for Windows 10 devices in late May 2026 and will expand to Windows 11 and other supported versions by fall 2026. Organizations will need to ensure that Microsoft Update is enabled in their update management strategy to receive these updates. The new delivery mechanism is expected to improve protection against evolving threats. Admins relying on manual update packages will need to adjust their processes accordingly.
