Question Changing programs process priority via Command Prompt

[mcqc]

I was trying to change the priority via Command Prompt. It didn't work and I got this message.

I don't know anything about programming, Does this will affect anything ? If yes, can I revert the change ?

Thanks

I did some research. Return value 5 mean access denied. I need to run Command Prompt in administrative mode to make it work. It's working now

the research should also tell you to run the command prompt from elevated administrator
