Quick Assist is an application in Windows 10 much like Team Viewer, and it provides a quick way to support remote users. While Remote Assistance, which was originally part of Windows XP, is still available in Windows 10, Quick Assist is a more flexible tool and easier to use. Remote Assistance can also be vulnerable to attack, so it’s something you might want to disable.
