Now that Windows 11 is officially available, the support dates are also known. Therefore, I have extended the life-cycle diagrams to include Windows 11 and Microsoft Office 2021.

What’s new in the Windows 10 LTSC and Office LTSC lifecycle?

Microsoft is changing its product life cycle for the Long Term Servicing Channel (LTSC) for Office and Windows. Some will still know the LTSC version as LTSB. Previously, this Windows 10 version, which was not intended for office environments, had a life cycle of 10 years. Microsoft Office LTSC, also known as Microsoft Office 2016 and Microsoft Office 2019) also had 10 years at the beginning, but this has already been reduced to 7 years with MS Office 2019
