Microsoft has released its June 2026 Patch Tuesday updates, addressing over 200 security vulnerabilities across Windows and related products, including multiple zero-day flaws — at least one of which is being actively exploited in attacks.
This is one of the largest Patch Tuesday releases of the year. Key details:
- 200+ vulnerabilities patched across Windows, Office, Edge, and other products
- Multiple zero-days disclosed, with at least one actively exploited in the wild
- Updates affect Windows 11 core shell performance and security
- New Secure Boot certificate validation requirements introduced
The June update also brings several functional improvements:
- Bluetooth LE Shared Audio support
- Multi-app camera usage capabilities
- Task Manager NPU metrics for monitoring AI workloads
- Core shell and app launch performance improvements
Security researchers are urging organizations to prioritize these updates immediately given the active exploitation of at least one zero-day. The growing concern is that AI-powered tools are making the race between patch and exploit shorter — giving defenders less time to respond before vulnerabilities are weaponized.
Microsoft has not yet disclosed the full scope of the actively exploited flaw but confirmed that targeted attacks have been observed in the wild.
