This is a very useful tip.  If you'd like to see if who's connected to your computer go to a DOS prompt and type:

netstat -n

Useful if you're on a network PC or if you fear that hackers are stealing away your files  :cool:

I just did that, lol. What happened?!? i got a DOS window that quickly came up and left, and I dont know what it said? Hope i didnt do anything to my pc.

Uh oh...By doing that you just deleted half of your system's .dll files

Seriously though, what you need to do is go to 'Start', 'Run', type cmd and then type in the command
