Description
A system faces an increased vulnerability threat if the built-in guest account is not renamed or disabled. The built-in guest account is a known user account on all Windows systems, and as initially installed, does not require a password. This can allow access to system resources by unauthorized users. This account is a member of the group Everyone and has all the rights and permissions associated with that group and could provide access to system resources to unauthorized users.
