Windows Vulnerability – Protecting Your System from Security Threats

Windows vulnerabilities are security flaws within the operating system that cybercriminals can exploit to gain unauthorized access, execute malicious code, or disrupt system functionality. These vulnerabilities may arise due to outdated software, misconfigurations, or unpatched security loopholes. Attackers often leverage them for ransomware attacks, data breaches, or privilege escalation. To mitigate risks, users must regularly update their Windows OS, apply security patches, enable firewalls, and use endpoint protection. Proactive cybersecurity measures help safeguard personal and business systems from emerging threats.
