Very nice, but you should maybe add a
check for to small buffersize in the GetStringValue function so that you don't have to run the function twice if you use a char pointer that has recently pointed to a shorter string.
For example:
...
if((lRes=RegOpenKeyEx(hKeyRoot, pszSubKey, 0, KEY_READ, &hKey))!=ERROR_SUCCESS) {
SetLastError(lRes);
return false;
}


// If the given buffer for the string is too small (specified
// by rdwSize), rdwSize is increased to the correct value and the query is retried.
if(lRes = RegQueryValueEx(hKey, pszValue, NULL, &dwType, (unsigned char*)pszBuffer, &dwBufferSize)== ERROR_MORE_DATA)
{
rdwSize = dwBufferSize;
lRes = RegQueryValueEx(hKey, pszValue, NULL, &dwType, (unsigned char*)pszBuffer, &dwBufferSize);
}

RegCloseKey(hKey);
rdwSize = dwBufferSize;
