This above code working fine till windows 8.1
but in some of the cumulative updates & feature updates, not getting download url in windows 10.

I modified some code, now i am getting download url.

Modified code:-

res = update->get_BundledUpdates(&updatecol);
//res = updatecol->get_Count(&j);
res = updatecol->get_Item(0,&updateTmp);
res = update->get_KBArticleIDs(&updateKBIDs);
if (FAILED(res)) {
HandleError(L"Failed to get KB article ID list", res);
goto innerCleanup;
}
res = updateTmp->get_DownloadContents(&pDownUrl);
if(SUCCEEDED(res))
{
BSTR url;
res = pDownUrl->get_Count(&count);
res = pDownUrl->get_Item(0, &downloadContent);
if(FAILED(res))
{
HandleError(L"Failed to get url article ID count", res);
//goto innerCleanup;
}
else
{
res = downloadContent->get_DownloadUrl(&url);
if(FAILED(res))
{
//goto innerCleanup;
}
else
{
std::wcout << L"URL" << L':' << url <

I got this code from following link
https://gist.github.com/apsun/b471c2e11dab94ad690d

where i added this code

res = update->get_DownloadContents(&pDownUrl);
if(SUCCEEDED(res))
{
BSTR url;
res = pDownUrl->get_Count(&count);
res = pDownUrl->get_Item(1, &downloadContent);
if(FAILED(res))
{
HandleError(L"Failed to get url article ID count", res);
//goto innerCleanup;
}
else
{
res = downloadContent->get_DownloadUrl(&url);
if(FAILED(res))
{
//goto innerCleanup;
}
else
{
std::wcout << L"URL" << url << L':' << std::endl;
SysFreeString(url);
}
}

In above section i am not getting download url.
