Microsoft has issued a final warning that Windows 11 23H2 Home and Pro editions will stop receiving critical security updates on November 11, 2025, leaving systems vulnerable to emerging threats. Users must upgrade to newer versions like Windows 11 24H2 or 25H2 to maintain protection, though some devices face upgrade blocks due to incompatible drivers. This move underscores the relentless pace of software lifecycles and the urgent need for developers and IT teams to prioritize update strategies.
