OK. I think I was able to find the answer myself.
Assuming you allready has the programs installed etc.
Press windows and type cmd:
Then Right click and chose “Open file location”
which should take your here as shown under:
Then copy that shortcut shown above (Node.js command promt), which is most likely to found here for most users:
Then press windows again and type run + enter, (or win logo + r) and you should get as shown beneath:
Type “shell:startup” and enter
Then the startup menu opens, and you past the previous copied shortcut into the startup menu.
Mine looks like this.
Startup menu should be found here:
C:\Users\ YOUR USER NAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
Now the comand promt will start twice at boot (in my case), but now we need to do the magic
Right click the CMD + Properties
In the Target window your should see:
C:\Windows\System32\cmd.exe /k “C:\Program Files\nodejs\nodevars.bat”
Then add something like this this: & “CD C:\Users\ YOUR USER NAME\roon-remote-master & node .”
So everyting should be like this:
C:\Windows\System32\cmd.exe /k “C:\Program Files\nodejs\nodevars.bat” & CD C:\Users\ YOUR USER NAME\roon-remote-master & node .
What you add depend of cause where you already is running your node.
