How this will affect your organization

The October 2025 monthly security update will be the last update available for these versions. After this date, no further security updates, bug fixes, or technical support will be provided. Devices running these versions will become unsupported and may become vulnerable to security threats, compliance risks, and increased exposure to cyberattacks.

What you need to do to prepare

Inventory your devices to identify those still running Windows 10, version 22H2, Windows 10 2015 LTSB, and Windows 10 IoT Enterprise LTSB 2015.
Upgrade eligible devices to Windows 11 using solutions like Microsoft Intune, Windows Autopatch, or Windows Autopilot.
Enroll eligible devices in the Windows 10 ESU program, if they cannot be upgraded in time, to continue receiving critical security updates.
