Accounts: Built-in Guest account must be renamed

20dbd0a4-0373-4913-9f75-4ab7f6fcbdb0

The built-in guest account is a well-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. Renaming this account to an unidentified name improves the protection of this account and the system.

Remediation

To fix this configure the policy value for:
Computer Configuration
|_ Windows Settings
|_ Security Settings
|_ Local Policies
|_ Security Options
|_ "Accounts: Rename guest account" to a name other than "Guest".
