Windows Server 2016 End of Life Date
Windows Server 2016 end-of-life date, support status, and CVE risk. Data from endoflife.date and official vendor documentation.
Windows Server 2016 was released on October 15, 2016 and support is scheduled to end on January 12, 2027 — a planned supported lifespan of 10 years and 3 months, in line with the 10 years and 2 months median for Windows Server 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 Server 2016 end of life mean?
When Windows Server 2016 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 Server 2016 past its EOL date creates a permanently growing attack surface that standard security tooling will not surface.
Migrate to Windows Server 2025 or implement compensating controls — network segmentation, enhanced monitoring, restricted access — while migration is underway.
