If you want to increase priority of your thread up to max you must 
to increase process class priority as well as thread priority.

Two Win32 API function do it - SetPriorityClass for process 
and SetThreadPriority for thread. 
It can be look as follow:

bool res=SetPriorityClass(
    GetCurrentProcess(),	// handle to the process  
    REALTIME_PRIORITY_CLASS // priority class value 
   );
bool res1=SetThreadPriority(
    GetCurrentThread(),	// handle to the thread 
    THREAD_PRIORITY_TIME_CRITICAL  // thread priority level 
   );

Two additional things:
1. It is a really bad idea to make such thing for a long time. 
This way you can stop some very important process in the 
operating system and come in the deadlock.
2. If you work in Windows NT/2000/XP there are only some 
user can increase priority (as a rule it is local Administrator). See Control Panel -> Admin -> Local policy -> 
user rigts.
