How do I login on my friends computer?

Unless you have permission to be on there, stay off of it.

Ben

Create a new account, with his permission of course.

Ask ur friend for the account and password.

For you to be able to log on the computer as "you" they would have to go into the settings (or control panel) and add you to the computer as a user. if you are trying to hack iinto their computer, you would need to somehow get their id and password.
