How to access other computer remotely?

You can do this, but you will have to do 1 thing before accessing your friend's computer. You will have to change some settings on your friend's computer. Following are the steps to access your friend's computer:

• Firstly, know the IP address of your friend's computer. An IP address is a unique address assigned to a computer that is connected to the internet. You can know the IP address from https://whatismyipaddress.com.
• After knowing the IP address of your friend's computer change some settings on his computer by:

Go to control panel -> System -> Remote Settings-> Check allow remote assistance connections to this computer

Now you are almost done and ready to access your friend's computer. Go to your home and connect your computer with internet. For accessing your friend's computer do the following steps:

• If you are using Windows XP, then:

Go to all programs -> accessories -> communication -> Allow Remote Desktop Connection

• If you are using vista/7

Then search for Remote Desktop Connection A dialog box of remote desktop connection will pop up. Enter the IP address of your friends computer in the text field and click connect and you can access each and every type of information on his computer.

This type of window will appear when you start a remote desktop connection. But 1 thing I should tell you. The task which you want to perform is not an ethical task. Accessing anyone's private data without his permission is not a good thing. It's OK when you do it for fun but not for damaging or misuse of your friend's computer.
