UAC

Dear @Colinb2

thank you for your question.

UAC stands for User Account Control and it's the "famous" pop-up that appears in Windows when you want to run tasks that require administrator privileges.

If you want more information please take a look here: https://en.wikipedia.org/wiki/User_Account_Control

If you want to know how to control it with TeamViewer please take a look here: https://community.teamviewer.com/t5/Knowledge-Base/Controlling-the-UAC-on-remote-Windows-PC/ta-p/25595

Take care,

Giovanni.
