What do you mean by "Critical"? Do you mean the process priority?

There are normal APIs for setting the priority. Try SetPriorityClass and use REALTIME_PRIORITY_CLASS.

The NT* APIs are not officially documented. It is not recommend to use them. AFICT you don't actually gain anything by using them anyway.

I wonder what is the valid usecase for increased priority of a process? Except making users angry.
