Yeah, only INTERNET_OPTION_PROXY_USERNAME and INTERNET_OPTION_PROXY_PASSWORD
are needed.

- If InternetSetOptionW for INTERNET_OPTION_PROXY_USERNAME return FALSE, then
INTERNET_OPTION_PROXY_PASSWORD is not set, fdm.exe fail to download files;
 - If InternetSetOptionW for INTERNET_OPTION_PROXY_USERNAME return TRUE, then
the application will try to set INTERNET_OPTION_PROXY_PASSWORD:
   - If InternetSetOptionW for INTERNET_OPTION_PROXY_PASSWORD return FALSE,
then fdm.exe will still fail to download 
   - Instead, if InternetSetOptionW for INTERNET_OPTION_PROXY_PASSWORD return
TRUE as well, fdm.exe will start to download.
