Not to mention there is no admin anymore, it's essentially a sudo style with it popping up asking are you sure.

This though really reeks of their son dragged and dropped their old files onto a new computer and didn't set the NTFS permissions, and purposely set them up as a non admin so they wouldn't bother them with "I got a new virus". When I have an elderly relative ask for me to set up their computer I don't give them admin rights
