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.

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.
