In Windows, is 0 valid PID for a process or is it reserved by OS?
It would be nice if you can provide a link to a doc that says it is reserved or what.
Thank!

Open task manager – switch to the processes tab (maybe click “View”, “Show columns” and enable the PID column).
PID 0 is the System Idle Process. Since that process isn’t really a process and never exits, I suspect that it is always the case.
No documentation available to me, but I’m pretty certain this is always going to be the case.
