No updates for consumer versions of Win10. Including security ones. If on October 15th a zero-day exploit is out in the wild, Microsoft would not be obligated to patch it.
You said no updates for the consumer version, but there will be optional paid extended support available for consumer users who opt to pay for updates for a year.
You’d be surprised. I run a small IT business and I have many elderly customers on a fixed income. Linux is unfortunately not an option for most. Some have opted to buy a new or used W11 compatible PC, but many will be paying for extended support. For $30 for the whole year, it’s much cheaper than a whole new computer.
