Microsoft releases Windows 10 KB5099539 extended security update
The update also improves File Explorer, Widgets and Bluetooth while raising concerns over two exploited flaws and a publicly disclosed BitLocker issue.
- On Tuesday, July 14, 2026, Microsoft released security patches for a record 570 Windows vulnerabilities as part of its monthly Patch Tuesday cycle, surpassing the 206 bugs fixed in June and 164 in April.
- Microsoft attributes the surge in patches to its internal AI-powered multi-model agentic scanning harness, codenamed MDASH, which identifies vulnerabilities that engineers then patch using human and AI-powered tools.
- Among the fixes, three are zero-days with two already exploited in attacks, according to security provider Action1, including flaws affecting Active Directory and Microsoft SharePoint.
- Security researchers warn that organizations should expect more frequent updates as Microsoft accelerates development; "Systems deployed in remote locations or shared environments may be particularly vulnerable," per Action1.
- Beyond security fixes, the July update enhances Windows features including File Explorer and Bluetooth connectivity, while Microsoft introduced options to pause updates until specific dates for improved user control.
