Windows 11 LTSC appears several years after 21H2 based Windows 10 LTSC
Windows 11 is getting a Long-Term Servicing Channel release and it will probably appear in three years. Microsoft will then support the LTSC version of Windows 11 for five years, as well as the upcoming LTSC Enterprise release, which is based on Windows 10 21H2.
Windows 11 LTSC, the version of Windows with relatively long support, will not appear until 2024 at the earliest. This can be concluded from comments from the company during an ask me anything session, which was noticed by Peter. Microsoft reports that anything can happen in that time span, but that Windows 11 LTSC will receive five years of support.
That is just as long a support period as the upcoming LTSC release of Windows 10 Enterprise. It will appear later this year and Microsoft bases it on the 21H2 release of Windows 10, of which test releases have now been released.
Microsoft will support the LTSC release of Windows 10 for ten years, but that will change with the upcoming 21H2 release. The current LTSC version of Windows 10, based on version 1809, will retain its 10-year support, which will not end until 2029. There are two LTSC variants: Windows 10 Enterprise LTSC and Windows 10 IoT Enterprise. The IoT Enterprise edition will retain support for up to ten years. The LTSC releases are intended for systems that need to run on a single version of the OS for a long time.
Unlike Windows 10, Windows 11 does not receive two major updates per year, but a single one, with 36 months of support. With this, the company caters to IT administrators. According to Microsoft, the decision to release a single feature update per year was made in response to feedback.
