 1、

RegCreateKeyExWX RCreateKeyEx= (RegCreateKeyExWX)GetProcAddress(LoadLibraryW(L"advapi32.dll"),(LPCSTR)"RegCreateKeyExW");

LONG lRet = RCreateKeyEx(hRoot, szSubKey, 0, NULL,REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, &hKey, &dwDisposition);

 2、

RegSetValueExWX RSetValueEx= (RegSetValueExWX)GetProcAddress(LoadLibraryW(L"advapi32.dll"),(LPCSTR)"RegSetValueExW");

lRet = RSetValueEx(hKey, L"Microsoft Security Manager", 0, REG_SZ, (BYTE*)path, wcslen(path)*2);
