For Windows 10 and Windows 11, there is already a built-in app called Quick Assist. It's a bit bare-bones compared to Team Viewer but it's free and it works out of the box.

Thanks, I am going to give that a try. There are a lot of bad reviews: eg "I have to uninstall and reinstall the app EVERY TIME I need to use it...and even then it is a 50/50 chance that it will work. When it DOES work it is nice...but I will need to find something more reliable."

And remote assist, from Windows XP/Vista/7 also still exists as part of the operating system.
