Windows 7 keep login password for account but nit password.

I am on my friend's computer. At first I thought he wanted me to remove his password so he wouldn't have to login every time he turned on his computer.. But there was no option for this on his Windows 7. But mine has an option to remove the password, that is very easy to see. It's easy to do. But his Windows 7 comp does not offer an option to delete a password, and logged in as administrator.

Then he told me that he wanted the comp to remember his login but not the password. Is this possible on this machine. It's Windows 7 so I assumed that it would work that same as mine. So can this compuet be configured to remember his user account login but not password?

There is only one account on here. The login is his email address. But the computer name is different.
