Windows 11 2022 Update (codenamed Sun Valley 2) is a major feature update for Windows 11 released on 20 September 2022. It includes minor improvements to the core experience, such as support for third-party Widgets, a redesigned Task Manager, as well as certain functionality omitted from the original release of Windows 11, such as drag-and-drop support for the taskbar. It is the last version of Windows to support Qualcomm Snapdragon 835 and earlier SoCs.
References to a future 22H2 update based on the Copper codebase were first unintentionally added to telemetry documentation in April 2021 alongside similar references to the initial Windows 11 release, as well as the Windows 10 November 2021 Update. The target later shifted to Nickel, with build 22567 being the first Insider Preview build to include version 22H2 branding.
Unlike the original release of Windows 11, the 2022 Update itself wasn't officially announced at all until its general availability on 20 September 2022. The only known public reference to the final name before its release was introduced in an update to the Get Started app pushed in late August 2022 and was reverted soon afterwards.
The internet connection requirement during device setup has now been extended to the Pro edition.
Games running in windowed mode now properly support Auto HDR and VRR.
Smart App Control has been added.
Hyper-V ARM Generic Arch Timer support has been added.
Windows Sandbox, .NET Framework, and Internet Infomation Services (IIS) now have a version that runs natively on ARM64-based devices.
Added the /machine parameter to the start command, which specifies what architecture to start the process with (applicable to .NET Framework AnyCPU apps and ARM64X apps).
Attempting to run ARM32 apps on ARMv8 processors that do not support the ARMv7 instruction set will cause the "This app can't run on your PC" message to appear, rather than crashing directly in previous versions.
This release introduces a new kind of updates called Moments, which will ship multiple times a year and will consist of a limited set of new features backported from contemporary Dev builds. They use the same mechanisms used for Windows 10 feature updates released after the May 2020 Update, which are mere regular updates applied on top of build 19041 that happen to enable new experiences and bump the reported version information. Similarly, moments also bump the reported build number, although it is unknown whether they will also end up changing the version identifier.
Moments are reportedly a part of Microsoft's revised development cycle with a new major version of Windows releasing every three years, while the period between two major versions is spanned by frequent feature drops.
