It's not directly your answer but I highly recommend this for elderly relatives and anyone susceptible to scams: I grabbed the signing certificates for Anydesk, Logmeinrescue and all the common "remote management" apps, and block them in Applocker. I've taken the phone call that says "I have the police on the phone and they need me to do something but the computer keeps blocking it, what do I do??". That's how you know you just saved them from a horrible mistake.
