KB5079391 is a non-security optional preview update for Windows 11, released 2026-03-26, producing OS build 26200.8116. It closes no vulnerabilities, so it carries no Severity rank and appears in no security feed.
Update summary
This is a non-security update: it fixes no vulnerabilities and carries no CVEs, so it has no Severity rank and no CVSS score. It is not in Microsoft's security feed, which is why most vulnerability trackers do not list it at all. Installing it is a reliability and features decision rather than a risk one.
A newer security update for Windows 11 has shipped since this one: KB5101681 (2026-07-28). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
