Windows 10 22H2 is a feature update for Windows 10, released in September 2022. "22H2" refers to the year (2022) and the second half of the year (H2). It[SQ]s essentially a minor update compared to larger feature updates like the ones that used to come annually (e.g., the jump from Windows 10 version 1803 to 1903).

While it didn[SQ]t introduce massive new features like a completely redesigned interface, 22H2 included several smaller improvements and bug fixes focused on stability, security, and performance enhancements. These improvements were often cumulative updates that had been rolled out previously; 22H2 bundled them into a single package. Think of it as a service pack for Windows 10, delivering the latest patches and refinements.

Because Microsoft ended support for Windows 10 on October 14, 2025, Windows 10 22H2 is no longer receiving security updates. Anyone still using it is highly vulnerable to malware and other security threats. It is strongly recommended to upgrade to Windows 11.
