HANDLE hproc;
#define GFWindowsLiveAdd  0x00A0D690
BYTE GFWLBypass[] = {0xc2, 0x0c, 0x00};
BYTE GFWLBackup[] = {0x8b, 0xff, 0x55};

void BypassCrcCheck(bool BypassGFWL)
{
    hproc = OpenProcess(PROCESS_ALL_ACCESS, false, GetCurrentProcessId());

            if(!BypassGFWL)
            {
                WriteProcessMemory(hproc,(LPVOID)GFWindowsLiveAdd, &GFWLBackup, sizeof(GFWLBackup), W);

            }
            else
            {

                WriteProcessMemory(hproc,(LPVOID)GFWindowsLiveAdd, &GFWLBypass,sizeof(GFWLBypass), W);

            }
}
but its not working. so can u do with asm ? like that
void BypassCrcCheck(bool BypassGFWL)
{
    hproc = OpenProcess(PROCESS_ALL_ACCESS, false, GetCurrentProcessId());

            if(!BypassGFWL)
            {
                __asm
{
...
}

            }
            else
            {

                __asm
{
..
}
            }
}
