This table summarizes the Windows client and server releases supported by the Windows App SDK (the following sections provide details on the various servicing categories, channels, and SKUs for each OS).

Windows App SDK	Release date	Windows client	Windows Server

Windows client SKUs and channels

The Windows client OS runs on personal devices such as workstations, desktop PCs, laptops, and tablets.

There are four servicing categories that apply to various combinations of Windows client SKUs and servicing channels.

Servicing channel		SKU	SKU
		Home, Pro	Enterprise
GA*		Shortest servicing	Short servicing
LTSC**	Mainstream	N/A	Long servicing
	Extended	N/A	Longest servicing

* The General Availability (GA) servicing channel includes the majority of Windows devices.

** The Long Term Servicing Channel (LTSC) includes devices that need to continue running older versions of Windows.

Five older versions of Windows client are still in service for at least one servicing category. Each version will continue to be supported by the Windows App SDK until the latest applicable Windows servicing end-date for that version. The following table shows the end-date for each servicing category.

Version	Build	Servicing end-dates				Max end-dates
		GA Home, Pro	GA Enterprise	LTSC Mainstream	LTSC Extended
Win10 1809	17763	Past	Past	Past	2029-01-09	2029-01-09

Note

Windows App SDK does not support IoT SKUs.

Windows Server SKUs and channels

Windows Server is the platform for building an infrastructure of connected applications, networks, and web services, from the workgroup to the data center. Windows Server offers services to other devices, has more features and capacities than a client OS, and can support more network connections.

The following table shows the end-date for each servicing category.

Version	Build	Servicing end-dates		Max end-dates
		LTSC Mainstream	LTSC Extended
Server 2019	17763	Past	2029-01-09	2029-01-09
Server 2022	20348	2026-10-13	2031-10-14	2032-01-13
