Take a look at faq #7593. I think following quote applies to your code also: "Under NT and Win2K, the process issuing the SetPriorityClass call must have a process handle with the PROCESS_SET_INFORMATION access right, which may require calling AdjustTokenPrivileges, a non-trivial issue."

See mskb #Q251310 for how the process token security can be ajusted.
