Lifecycle detail
Windows 10-21h2-e-lts was released on November 16, 2021 and support is scheduled to end on January 12, 2027 — a planned supported lifespan of 5 years and 2 months, shorter than 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 Enterprise LTSC 2021 end of life mean?
When Windows 10 Enterprise LTSC 2021 reaches end of life, the maintainers stop issuing security patches for this version except under Extended Security Updates (ESU) (paid), until Jan 12, 2030. 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: A CVE-based scan does not show the ongoing accumulation of unpatched vulnerabilities in EOL software versions. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. Running Windows 10 Enterprise LTSC 2021 past its EOL date creates a growing attack surface that a clean scan result does not rule out.
Migrate to Windows 11 26H2 (E) or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
