A recent patch release from Microsoft has addressed a large number of vulnerabilities, with reports varying on the exact number, ranging from over 570 to more than 600. The update is said to include fixes for critical flaws and zero-day exploits, with some outlets specifying that 63 critical flaws and two or three actively exploited bugs were addressed. The patch release is referred to as both the March 2026 and July 2026 Patch Tuesday, suggesting a possible discrepancy in the reported timing.
