Microsoft issued an out-of-band cumulative update (KB5086672) for Windows 11 versions 24H2 and 25H2 to replace a broken optional preview update (KB5079391) that triggered installation errors (0x80073712). The update supersedes prior March 2026 security and non-security preview updates; the report also references other recent emergency fixes (account sign-in issues, Bluetooth visibility, RRAS vulnerabilities) and troubleshooting guidance but does not describe active exploitation or a cyber attack.
