Microsoft released 570 security patches in July with nearly 60 critical flaws and three zero-days actively being exploited, including elevation of privilege bugs and a BitLocker bypass. All Windows environments are affected. AI-accelerated exploit development means these vulnerabilities are moving from disclosure to weaponization faster than traditional timelines.
