HDD serial number flipped every 2 bytes in Windows XP, Vista and 7 but not in Windows 8

Question

I need to get HDD serial number to use it as a key for licensing a software. I used diskid32 code in this url: http://www.winsim.com/d

Answer 1

Just turn off the flip using the "flip" flag of the flibAndCodeBytes function when windows 8 or greater.

bool shoulFlipBytes = true;
if(IsWin8OrLater()) shouldFlipBytes = false;

flipAndCodeBytes(buffer,
                 descrip->SerialNumberOffset,
                 shouldFlipBytes,
                 serialNumber);

You can use this to check for windows version:

#include 

bool IsWin8OrLater() {
    DWORD version = GetVersion();
    DWORD major = (DWORD) (LOBYTE(LOWORD(version)));
    DWORD minor = (DWORD) (HIBYTE(LOWORD(version)));

    return (major > 6) || ((major == 6) && (minor >= 2));
}
