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 | |
|---|---|---|---|---|
| LTSC Mainstream | LTSC Extended | |||
