  1. What you want is something like this…

    NTSTATUS hStatus; SYSTEM_PERFORMANCE_INFORMATION             stSysPerfInfo;  hStatus = NtQuerySystemInformation(SystemPerformanceInformation, &stSysPerfInfo, sizeof(stSysPerfInfo), NULL); if (hStatus != NO_ERROR) {   // Do work.... }

    Or take a look at this ‘TaskManager’
