Background for this topic.
Patch Tuesday is the second Tuesday of each month, when Microsoft publishes a scheduled set of security and quality updates for supported products. The term is also used broadly for the recurring monthly patch cycle that organizations use to review, test, and deploy vendor fixes. Releases may address vulnerabilities in operating systems, applications, browsers, and infrastructure components, with severity and affected versions varying by update.
For security teams, the release is a trigger for vulnerability-management work: identify exposed and supported assets, assess whether a flaw is being exploited or affects a critical system, and prioritize deployment accordingly. Testing and staged rollout can reduce compatibility and availability problems, while leaving internet-facing or unpatched systems exposed can increase the chance of compromise. Teams should also account for patches that require reboots, configuration changes, or dependent updates, and track exceptions with compensating controls. Critical fixes may warrant accelerated or emergency deployment rather than waiting for the normal maintenance window.
