When upgrading Windows remotely via Logmein Rescue, will support session automatically reconnect?

I wish to upgrade a client's computer remotely using Logmein Rescue. I have upgraded systems from Windows 7 or Windows 8.x to Windows 10  before, but not remotely. My client is elderly and not comfortable with technological things, so I'd prefer she not have to interact with the computer at all. I don't want be locked out of her computer upon rebooting, due to dialog boxes requiring input to move forward. Has anyone had experience with this?
