I don't run from the PC anymore, but when I did (back in XP), I put xlights.exe in the startup folder and set the PC up so there was only one account with no password. That way if the system rebooted it automatically came up with xlights running and if it is running the scheduler would start the show. I know it is a little more complicated these days, but I think google will be your friend here. I do know that if there is only one user and no password the PC will boot right up as though you had logged in because I have done that when building a new Win10. I don't put in a password until I'm ready to put the system in production or turn it over to a user even though Windows will complain about it. I would google how to autostart a program in win10 at bootup and also auto logon a particular user in win 10.
