You definitely do not have to retire it.
You can pay $30 a year to Microsoft or a third party.
Or you can use one of the many techniques to put Windows 11 on it and see how well that works for you. Or you can install a version of Linux.
Unfortunately, my computer skills are completely average.
Since everything important in my life is at least partly Web-dependent, I tend to panic when hardware or software is not behaving as expected.
