I've just installed Win2K and user logins are new to me

1/ Can I delete the "Administrator" user ? (Is there a specific reason i
shouldn't)
        I already have administrator privileges under my login
        I dont want other users to have this privilege
        I dont want to create the "Administrator" user with a password (it
just a waste of space, since no one will ever use it)
        I just dont want it available (but it wont let me delete it)

The only answer i can figure, is to delete myself (i already have customised
my environment), and rename the "Administrator" to "Me", then do alllllll my
customising again

2/ Which is the user type with the least priveleges?
        From the help it looks like "Guest", but i cant really tell

3/ I have set up a guest user as "Guest" (no password) but i would like any
guest to have access to the web via my dial-up connection
        They can dial up as they login, but if the connection goes, they
will have to log out & back in again

Maybe I chose the wrong type of user (I want them to have access to all
application & web access but no settings)

P.S. I know i should post these one-by-one but im sure you've all been
through this 100's times
