Just got off the phone with the owner of the PC. I tried to add a user with Admin privilege's and come to find out he is not logged in as Administrator. His son-in-law is the administrator. The last time he spoke to him, he could not remember the password he set for this machine.
I gave the owner two options, have his son-in-law remember the password, or I'd reload WIN 10 with my iso USB and go through the updates since the time I downloaded the iso.
In any case his son-in-law can not fix his PC because this PC has an older version of Team Viewer and the newer version is not compatible with the old. So he is between a rock and the hard place.
Unless he brings his PC to his son-in-law, nothing can be updated.

My suggestion was for me to re-load WIN 10 and make him the Admin so at least he can do updates. I'll see what happens after he has a conversation with his son-in-law.
