February 2026: is it safe to deploy?

What Microsoft fixed, how urgent it is, and whether anything broke, per Windows version, from Microsoft's release tables, release health, MSRC, CISA, and what the community reports.

Superseded

Newer updates replace February 2026.

The CVEs it fixes are unknown; no open known issues found in the current public evidence; out-of-band fixes followed on 2 Mar. See November 2026 Patch Tuesday.

MSRC's February 2026 security update document isn't collected.
