Patch Panic: Microsoft Fixes 6 Active Zero-Days in Feb 2026 Update

Microsoft's February 2026 security update fixes 61 vulnerabilities — including six zero-days actively exploited in the wild — with the most urgent being CVE-2026-21519 in the Desktop Window Manager (DWM) that allows elevation to SYSTEM on virtually all modern Windows machines; administrators are strongly advised to prioritize the DWM patch while other critical and important fixes (RCE, DoS, security bypasses, privilege escalation) are applied.
