In this case, you may need to set the DWORD value in registry of TcpWindowSize and
DefaultRcvWindow to 65536 at:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters. If
TcpWindowSize or DefaultRcvWindow does not exist, you need to create a new
DWORD entry for them and then set the DWORD value to 65536.
To create a DWORD entry, see the following steps.
