Boost Internet speed and Windows Performance by up to 300 percent. WinBooster can speed up Internet transfers by changing many of the network protocol parameters. By default, Windows assumes that you are connected to a shared local area network and uses appropriate values for this arrangement. Most home users, however, connect via a modem using PPP (point-to-point protocol) and TCP/IP. By using values more suited to this type of connection it is possible to boost performance considerably.
