Windows 10 21H2 IoT End of Life Date
Windows 10 21H2 IoT end-of-life date, support status, and CVE risk. Data from endoflife.date and official vendor documentation.
Windows 10-21h2-iot-lts was released on November 16, 2021 and support is scheduled to end on January 13, 2032 — a planned supported lifespan of 10 years and 2 months, in line with the 10 years and 2 months median for Windows LTS releases. It is a long-term support (LTS) release, so it carries a longer patch window than the interim releases around it.

What does Windows 10 21H2 IoT end of life mean?
When Windows 10 21H2 IoT reaches end of life, the maintainers stop issuing security patches for this version. CVEs discovered after the EOL date are publicly disclosed on the National Vulnerability Database with no patch available. Exploit code frequently appears on GitHub within days of disclosure.
The CVE blind spot: Most vulnerability scanners check for known CVEs but do not flag the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Running Windows 10 21H2 IoT past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to Windows 11 26H1 (E) or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
