This very topic is an example of why, if you don't need unattended access (and I know that many do) that I have fallen in love with Quick Assist.
It is the analog to Windows Defender in the in-person remote assistance arena. Comes with Windows, works incredibly well, has zero "side effects" of any kind that I've ever experienced or read about, and does not involve the need to install anything.
I don't really care that there is no audio component, as I always have an open phone conversation going when I am actually doing this sort of remote work, at least if the assistee wants to watch or is needed to do something (e.g., if UAC is triggered interaction with it can only occur on the machine presenting the prompt, not remotely).
