Yes. So far, I haven't read or heard of any tweak to customize that behaviour.
In closing, I rarely see this in the office machines since we turn off the glitzy logon and use the classic logon as you see in Windows 2000.

I created an account with admin rights and then created another account, also with admin rights. The original Administrator is now hidden. The Quest account has been disabled. At the log in screen, these two 'created' user accounts come up to be chosen for logging in. However, in Safe Mode, only the original Administrator and the first created user accounts come up. The second user account does not appear. Is this by design ? Thanks.
