In most cases, guest accounts are disabled by default on web servers. This means that anyone who visits the server without providing a valid login name and password is not allowed to access any of the resources or files on the server. However, there are some exceptions to this rule.
Some web servers allow visitors to create guest accounts without having to provide a login name and password. This is typically done when the server is used for public access, such as in a library or online forum. Guest accounts can also be enabled by setting up a user account for guests on an individual web server.

There is not a specific way to disable the default account, but you can disable it by going to Settings > Accounts and disabling the default account.

There are a few ways to block a guest access from accessing files on your computer. One way is to use the computer’s firewall.  Another way is to use the Windows security features.  And lastly, you can use file sharing tools to limit guest access.
