Thread: retrieve computer info

Check the MSDN at www.msdn.microsoft.com and search for base services as well as the registry Win32 API calls.

GetSystemInfo (declared in windows.h) might be helpful:

Code:

VOID GetSystemInfo(
  LPSYSTEM_INFO lpSystemInfo  // system information
);

where LPSYSTEM_INFO points to following struct

typedef struct _SYSTEM_INFO { 
  union { 
    DWORD  dwOemId; 
    struct { 
      WORD wProcessorArchitecture; 
      WORD wReserved; 
    }; 
  }; 
  DWORD  dwPageSize; 
  LPVOID lpMinimumApplicationAddress; 
  LPVOID lpMaximumApplicationAddress; 
  DWORD_PTR dwActiveProcessorMask; 
  DWORD dwNumberOfProcessors; 
  DWORD dwProcessorType; 
  DWORD dwAllocationGranularity; 
  WORD wProcessorLevel; 
  WORD wProcessorRevision; 
} SYSTEM_INFO;

Furthermore perform a search for "Getting Hardware Information" on msdn.
