The Event ID 4226 Patch

Windows Vista, Windows XP SP2 and Windows 2003 Server SP1 limit the maximum concurrent half-open connections (SYN) to a maximum of 10
(the previous limit was over 65,000). The drawback to this connection limit is that network intensive applications can be slowed, including Peer-to-Peer (P2P) clients like µTorrent.

To change the limit on maximum concurrent half-open connections, effectively editing the TCPIP.SYS file, use the Event ID 4226 Patch.

A complete guide can be found here: Windows XP SP2 and the Event ID 4226 Patch
Windows XP SP2 and Windows 2003 Server SP1 Download
Windows Vista Download

Once the TCPIP.SYS file, has been patched, open µTorrent and navigate to:

Options > Preferences (Ctrl+P) > Click "Advanced" > Click “net.max_halfopen” > Enter "50" in the "Value" Field > Click "Set"

Do not change the “net.max_halfopen” value, without first patching the TCPIP.SYS file, using the Event ID 4226 Patch.

To truly optimize µTorrent, set the limit to 50 and use µTorrent normally; periodically check the Windows Event Viewer for Event ID 4226 errors;
if these errors are found, raise the limit by 50, continuing this process, until these errors are no longer logged.

To access the Windows Event Viewer, navigate to: “Start” > "Run" > Enter " eventvwr.msc " > Click "Ok"
