Change the Default Keep-Alive Time-Out in Internet Explorer (All Windows)

When Internet Explorer establishes a persistent HTTP connection with a Web server it reuses the same TCP/IP socket until the connection is idle for one minute. This tweak allows you to change the time-out period which is useful if you experience connection problems.

This tweak can be easily applied using WinGuides Tweak Manager.
