I believe that you are asking why some sites passwords and/or usernames are not remembered. In such a case it is likely that either you cleared some type of history, data, etc, or possibly updated a web browser, or even got a new web browser. This may also be the case if the website was updated.
press the box beside " forget password "
forget my password
There is in some cases, password that remains in Gmail. That means the password is saved in the browser. You need to remove the password and then forget it in browser.
You click forgot password and they send your password to your email
click forgott your password
You can reset your Password on Skype's Website!
It should say below password. Forgot password. How do you get the username?
Officially there is no way. The security question was made specially for such cases, if you forget your password and your security answer you loose your email. Some services have one more option to reset the password to use another email address to send new password, but I think hotmail doesn't have it.

If you forget your Hotmail password, you will need to reset your password, by following the "I forgot me password" link. An email link for password reset will be sent to your secondary email address.
