Overview
Windows 10 is Microsoft's desktop operating system that supports a broad range of devices and enterprise deployments. It features a modern security model and relies on regular updates, with Extended Security Updates (ESU) used to extend support after mainstream lifecycles. In cybersecurity terms, it remains a high-priority patching target due to its persistent presence in networks and the complexities of ESU deployment, which can create exposure if enrollment or update delivery fails.
