CreateFile returns Access_Denied in Win10

CreateFile() returns ACCESS_DENIED in Windows10 when i try in my project. If i create sample application using CreateFile() it works fine. Even tried to check admin privileges before calling CreateFile(), user is in admin mode. Same code works fine in Win 7.

Below is code sample:

 WCHAR userPath[] = L"C:\\test.txt";
 HANDLE hFile = NULL;

 hFile = ::CreateFile(userPath,
 GENERIC_READ | GENERIC_WRITE,
 0,
 NULL,
 CREATE_ALWAYS,
 FILE_ATTRIBUTE_NORMAL,
 NULL);

 if(hFile == INVALID_HANDLE_VALUE)
 {
    wprintf(L"Error HANDLE = 0x%x \n",hFile);
 }
 else
 {
    wprintf(L"Suceess HANDLE = 0x%x \n",hFile);
    ::CloseHandle(hFile);
 }
