How to remove Guest option from login screen? I just started using a MacBook Pro in addition to my Windows 7 laptop (to see if the OS X 10.8 will be a good alternative for me). At Windows bootup, since my user is the only one on the computer, it is already selected at the login screen and I just type my password and go.

On OS X 10.8.2 it shows my name and a Guest account. I have to select my name with the mouse before I can type in my password. I can't even use the keyboard to tab over to my name:



How can I disable the Guest account from showing on the login screen so only my user is displayed with a password box?

In Users &amp; Groups the Guest user is disabled:



I also did some searching and found that this could be a side affect of the 'Find my Mac' feature of iCloud. I verified it is also disabled:



Any ideas?

OK, 
I see on your screen shot, that is not Guest user icon, that is Group user!

It says Other (not Guest). 

The Guest user shows with one face, the group shows with multiple faces, like your icon.

I see you are at work. 
Do you have a group user account set up by your IT people?

Let me clarify that. 
Someone or something (a program) has put a login and hidden it from you so you can not delete it. 

Well you can now do something since you know about it.
First lets find out who! then decide if you want to delete it.
