1 Support is ongoing. End dates and releases could still change
2 Exact date unknown
3 Technical support continued during the lifetime of the product, however only on a case by case basis without public patches and software updates. Thus assuming the end date to be the date of the last Service Pack or the discontinuation announcement, whichever is later.
4 Support is ongoing as a subset of a newer architecture. For example x86-64 CPUs can run x86 16-bit and 32-bit code and ARM64 CPUs can run ARM32 code.
Italic: Discontinued since more than 5 years
