Microsoft’s plan to end Windows 10 support next month — which may make an estimated 400 million PCs obsolete

I don’t get this. Can’t those PCs update to the new version? Yes, I am very aware that win11 is a shit show and win10 was better.

But Ubuntu also has a similar support policy for updates:

Ubuntu LTS versions get five years of updates, while non-LTS only gets nine months.

Would all the Linux versions out there be subjected the same 15 years of updates??
