Step 1: Install Microsoft Message Queuing
Open your window's Add/Remove programs and select Add/Remove Window's Components

From here, find Message Queuing and ensure it is installed. This service is necessary to change the default window settings.

Step 2: Set TcpAckFrequency
Open your registry by running regedt32 and find the key:
HKLM\System\CurrentControlSet\Services\Tcpip\Param eters\Interfaces\<Adapter ID>\
You can determine which Adapter ID is the correct one by looking for your IP Address listed on the right pane.
In the correct Adapter, add the DWord TcpAckFrequency and set the value equal to 1.
