How can I track which applications are using my internet connection?

[I Am The Walrus]

I have a very slow internet connection and every now and again it slows to a crawl because some or other applications are using it in the background - no clues in the system tray or task manager. Is there a way (maybe an app to download?) that I can track which apps are using my connection and how much they are downloading at a given moment?

If your internet slow. First you needed to goto internet options and delete cookies and temp. then reboot system and then click start and Accessories and system tools and do disk cleanup and tick them all and then click ok. and after that do a spyware scan or u can goto microsoft safety scan it's free http://www.microsoft.com/protect/product...anner.mspx

TCP-View will allow you to see which programs are making internet connections.
