You've probably noticed that the LEDs on your internet modem or router seem to blink all the time, even when you're not doing anything specifically internet-related such as browsing web pages or watching a video.  Clearly some of the background programs, or Windows itself, is talking to a server somewhere.  But which programs are using most of your internet bandwidth, and what are they talking to?

Glasswire is a program that lets you find out.  You can view the amount of data used by each internet protocol (web, email, ftp and so on), or by each program.  You can browse by any date or time period you choose.  And you can even see a real-time graph of your computer's internet usage too.  It's a great tool for troubleshooting connectivity or just learning about how "connected" all modern software and operating systems are.

Glasswire is a 15 MB download from www.glasswire.com and it's free.  It's malware-free according to VirusTotal and Web of Trust.  My thanks go to Lex Davidson for telling me about this truly excellent utility.
