In addition, if you are interested in what others do.
MC requires a User to be logged in to work, as it doesn't run as a Service on Windows. That means that whenever a HTPC needs to be rebooted, a User needs to log in; User ID and Password.
I have a keyboard connected to my PC so I could log in every time the PC reboots. But I want MC functional if there is a power failure while I am away, so I want the HTPC to reboot and log in automatically. So this is what I have set up. Windows logs in to my limited user account for the HTPC whenever I reboot it, and then opens MC all ready to go. In fact, if I have any issues with the HTPC I just reboot it and it is quickly in a known state with MC running, without further input from me. Very handy.
I forget the details on how to make Windows 10 automatically log in on reboot, but a Google should find the method easily enough.
Sure, a PC that reboots or wakes and logs itself in isn't particularly secure, but it can't be accessed from outside my home network without specific knowledge and passwords, it uses a limited account, and if someone has already broken into my home to access it, they could just take the whole PC. So it isn't so bad.
