Byron, a new network administrator at FBI, would like to ensure that Windows PCs there...

To ensure that Windows PCs are up-to-date and have fewer internal security flaws, Byron should focus on regularly applying the latest security patches and updates. This can be achieved by:

Downloading and installing the latest patches: Ensures that any vulnerabilities identified in the operating system and applications are fixed promptly.

Enabling Windows Automatic Updates: Automates the process of checking for and installing updates, ensuring that PCs are always protected with the most current security measures.

Regularly updating the system helps in closing security loopholes that could be exploited by attackers. Antivirus software and turning off unnecessary services (Option A) are also important, but they do not address the critical need for regular patching. Centrally assigning group policies (Option B) is useful for managing security settings but does not directly address updating and patching. Dedicating a partition and formatting with NTFS (Option D) is unrelated to keeping systems up-to-date.
