But I would not answer and will move to the public, unless there is private information.
@RJGSpace Please do not tag me in every single question. Our friendly Community have a much more availability than me 
There is no need in any special startup script.
If you use a docker version and our recommended command, it will be started automatically with the docker.
if you use a binary version (either [Tech Preview] Linux Installer Part 2 or [Tech Preview] Linux Storage Node & Updater or GUI Install - Windows | Storj Docs), they will start automatically after reboot too.
The only problem with Docker desktop for Windows - the docker itself will start only after login (this is how the Docker desktop works). The workaround is to create a scheduler job using Windows Scheduler to run the Docker desktop binary after PC start. You will be asked for user’s credentials to make it happen without login.
