They acknowledged the exact date in 2022 just before Windows 11 was released: https://learn.microsoft.com/en-us/lifecycle/products/windows...

But even then, what point are you even trying to make? Windows 10, like previous releases before it, when its support end, will mean it was supported for a solid 10 years. I mean, that's a lifetime in tech; 2015 was the iPhone 6s.

Why do I recall Windows 10 being referred to as "the last version of Windows" because it was supposed to be capable of being supported indefinitely as a rolling release distro?

And I'm nitpicking, but each version of Windows 10 was its own release with a lifecycle of 1-2 years, like Ubuntu. We don't say that Arch has been supported for a solid 22 years just because it's been able to be seamlessly upgraded for that long.

Also, if most major OS and device vendors provide 7-10 years of security updates, and many of them did that before, is it really that much of a "lifetime" to anyone but the outliers?

I wasn't making a point, just contradicting the assertion that we always knew the EOL
