Microsoft won't update your Windows 11 PC if it has these apps
(www.xda-developers.com)
This is a most excellent place for technology news and articles.
Windows 10 was released on July 29, 2015, Debian 8 was released on 26 April 2015, 3 months earlier. And you are comparing it with Debian 6, released 4 years earlier? Debian 8 extended long term support reaches end-of-life 30 June 2025.
You are right. I misinterpreted the information on wiki page. Debian 8's free LTS tier ended 2020 and the Extended LTS continues until 2025. Extended support is a paid service though and costs a lot more than a single Windows license. Microsoft offers a similar (also paid) service.
