Who controls the process control block(PCB)?

Recently, I have learnt about kernel and find a question that who controls the process control block(PCB)?The kernel or the process itself? Does it differ in different platform (windows/Linux)? So far, I know PCB is controlled in hardware, but I can't get to the right answer.

OS tracks all necessary information about each process running in the system in PCB. Process Control Block is a data structure representing a process in the OS.

Process control Block PCB is specially defined in the core of the OS for each process.

What Others Are Asking

What do we need to check before releasing a PCB design?

After making efforts in a period, I finally finish my PCB design. Next step is releasing them to factory for production. To be honest, I don’t want any mistake on my file which may interrupt further prodution process. So what points should I pay attention when I double-check my design?
