Ever want to show someone your screen but not want to go through the hassle of logging into a 3rd party tool and then grant them access to view your session (i.e. WebEx or GoToMeeting)? Well if you are on a Windows box you can use "shadowing". It basically allows you to interact with another persons terminal session in real time. All you need to do is the following:

1. Get the session ID for the remote user in question by opening Task Manager and clicking on the Users tab; the session ID will be next to their login name
2. From a command prompt or run box, type in

1. On the person's session who is being requested, a pop-up box will appear asking to allow the remote user to view your screen - Click OK
2. If all works as expected, you will see the report persons screen and see what they are doing!
3. To break out of the session, you can hit CTRL + *
