critical update
Must-install software fix
A critical update is a software patch that addresses serious security vulnerabilities or severe bugs requiring immediate installation.
Unlike routine updates, critical updates fix flaws that could be actively exploited by attackers or cause system failures: Install the critical update before connecting to public Wi-Fi.
The term appears in operating systems, antivirus software, and enterprise IT, where delaying critical updates poses significant risk.
