Now, open command prompt (Windows key + R to bring up the run box, then type: "cmd" (no quotes!) and click OK or hit enter.

Now type: cd Desktop <ENTER>

now type: pinger www.google.ca

Command prompt is very helpful if you need quick answers like when the computer was last installed, and a lot more info, just type: systeminfo <enter>
