These updates contain new features, services, and other major changes. Differences between the Semi-Annual Channel and LTSCĪs I noted above, Windows 10 devices in the Semi-Annual Channel receive twice-yearly feature updates, once in the spring and once in the fall. We designed the LTSC with these types of use cases in mind, offering the promise that we will support each LTSC release for 10 years-and that features, and functionality will not change over the course of that 10-year lifecycle. They are treated as a whole system and are, therefore, commonly “upgraded” by building and validating a new system, turning off the old device, and replacing it with the new, certified device.
These devices share characteristics of embedded systems: they are typically designed for a specific purpose and are developed, tested, and certified before use. Examples include medical systems (such as those used for MRI and CAT scans), industrial process controllers, and air traffic control devices. The Long-Term Servicing Channel (LTSC) is designed for Windows 10 devices and use cases where the key requirement is that functionality and features don’t change over time.
With the Semi-Annual Channel, devices receive two feature updates per year, and benefit from the best performance, user experience, security, and stability. If you ask someone from Microsoft, or read industry guidance, about the best strategy for managing Windows 10 updates, the overarching recommendation is to use the Semi-Annual Channel (SAC) as the default servicing channel for Windows 10 devices.
Organizations that leverage this approach are seeking the manageability and security of Windows 10 while staying on the same operating system version for the life of the device. use cases where devices are commonly treated as a whole system and are, therefore, “upgraded” by building and validating a new system, turning off the old device, and replacing it with a new, certified device. Examples of the latter include kiosks, medical equipment, and digital signs, i.e. Rundll32 " %~dp0bin\slc.dll ",PatchGatherosstateĬall " %~dp0bin\gatherosstatemodified.exe "Ĭopy " %~dp0bin\GenuineTicket.xml " "C:\ProgramData\Microsoft\Windows\ClipSVC\GenuineTicket\GenuineTicket.xml "Ĭscript /nologo %windir%\system32\slmgr.vbs /atoĭel " %~dp0bin\gatherosstatemodified.Update : The content in this post applies to PC and laptop type devices converted to Windows 10 Enterprise LTSC, and not devices purchased with Windows 10 IoT Enterprise pre-installed.
