Very small offices may not use purpose-built software. My dentist when I was at school was a one-person operation (he&#x27;s retired now).<p>Even if they are using purpose built software, by default Cortana watches what you type in everything and sends samples (at least) to Microsoft. You can turn Cortana off, but you can&#x27;t uninstall it or even stop it from running and you can&#x27;t be sure that Microsoft won&#x27;t just turn it back on anyway (unless you are an enterprise customer).<p>I just don&#x27;t understand why Microsoft doesn&#x27;t just allow all of that stuff to be turned off by everybody? I could be pretty happy with Windows 10 if it respected my privacy more.
