I registered first as aprit@hotmail.com. Never received confirmation email to this email, clicked few times to resend, I guess microsoft or having problems with your email server
I set both hide wp-login and wp-admin on, set access type error to forbidden 403. wp-login gives 403, but wp-admin gives 404.
As a side note, your sever or ip block has a problem with microsoft, outlook blocks your confirmation email.
