Microsoft Issues Record 622 Security Fixes with Help from AI Tools

July 16, 2026
Microsoft has released security updates addressing 622 vulnerabilities across its products, setting a new record and crediting AI systems for identifying more flaws, including two zero-days.

Microsoft Corporation released a record 622 security patches across Windows, Office, and other products during its latest Patch Tuesday update, according to PC Gamer. The company attributed the increased volume of fixes to its use of AI tools that help engineers identify more vulnerabilities.

Among the fixes were at least two zero-day flaws that had already been exploited. One affected Windows BitLocker, while another concerned Windows Server escalation vulnerabilities. The update also addressed a long-standing bug in Windows 11's Capability Access Manager that could consume up to 500 GB of disk space unnecessarily.

The cumulative update, labeled KB5101650, adds new functionality for users to defer system updates for up to 35 days. Microsoft noted that the patch may not yet be available for select Dell devices using Intel processors due to an unresolved performance issue it is addressing with Dell.

Microsoft has recently stated that its AI-powered security scanning efforts have surfaced more latent code issues than ever before, which the company expects will continue to increase patch volumes in coming releases.
