Enable this setting to remain connected after logging off. Modify the Internet Auto-Dial Settings (All Windows) Windows has the option to automatically dial your Internet Service Provider (ISP) to establish an Internet connection. This option can be controlled using this tweak. Optimize Broadband PPPoE Connections (Windows Me) This setting optimized the IP MTU value so that there is reduced packet fragmentation when using a broadband connection with PPPoE (Point-to-Point Protocol over Ethernet). Increase Transfer Rates with ICS and Broadband Connections (Windows 98) If you are using Internet Connection Sharing ("ICS") with a broadband connection then remove this key to increase the performance. Disable Automatic Modem Connections at Startup (All Windows) If remote connections are enabled in Windows, the system may try to initiate an Internet connection at Windows startup or at the start of many applications. This setting disables that behaviour.

Home : Network : Protocols TCP-IP Transmission Control Protocol Internet Protocol Enhancements WINS Windows Internet Name Service Enhancements Disable SSDP Discovery in Windows Messenger (Windows 2000/XP) Windows Messenger uses the Simple Service Discovery Protocol (SSDP) to attempt to locate upstream Internet gateways on UDP port 1900. This tweak allows you to disable Universal Plug and Play Network Address Translation discovery to reduce bandwidth and increase security. Change the Number of Simultaneous HTTP Sessions (All Windows) Popular Windows normally limits the number of simultaneous connections made to a single web server. This behavior can be seen in Internet Explorer when downloading multiple files from a web site and only a certain number will be active at any one time.
