It’s almost like the good ol’ days of install fests and the like! ‘End of 10’ is an organization that’s making it easy for Windows 10 users with computers that can’t upgrade to Windows 11, to install Linux instead of sending good hardware to the landfill.
Once updates end in October, Windows 10 won’t be secure and probably shouldn’t be allowed to connect to the internet. It will still continue to function though. You can buy a year of extended support for Windows 10 for $30, but it’s unclear whether there will be support after that.
Probably best to start switching to something else, or plan to run that PC offline.
