Another way is...

2. The normal screen will be replaced by the old style text box. 
3. Type 'administrator' in the top box and leave the bottom one blank. 
4. If no password has been set then this will get you logged in as the administrator 
5. and you'll be able to set a new password for your own account. 
6. You can often get logged in by typing 'guest' in the top box and leaving the bottom one blank, but you'll be restricted in what you can do.
