Microsoft's Extended Security Updates program doesn't replace all of those options; ESUs just provide the monthly security updates from Windows Update and only cover what Microsoft classifies as critical or important vulnerabilities, which means no fixes for security issues you can mitigate without Microsoft making changes to Windows.

To be eligible to install updates from the ESU program, devices must be running Windows 10, version 22H2," Microsoft says.

Microsoft on Tuesday warned that full security support for Windows 10 will end on October 14, 2025, but offered a lifeline for customers unable or unwilling to upgrade two years hence. "While we strongly recommend moving to Windows 11, we understand there are circumstances that could prevent you from replacing Windows 10 devices before the EOS date," explained Jason Leznek, a member of Microsoft's Windows Servicing & Delivery team, in an statement.

Microsoft says that all Windows 10 customers will be able to pay for three extra years of security updates through the company's Extended Security Updates program after the end of support date. The upcoming Windows 10 22H2 version is the final Windows release, with all editions to continue to receive monthly security updates until the EOS date.
