Windows also has TCP buffers auto-tuning since Windows 7/Vista up to 16MB, however only receiver-side tuning on their 
client versions,
for sender-side tuning you will need a server version.
That means uploading stuff from a regular windows "client" machine to a remote host with a large RTT will be very slow.
