Which action should be prioritized after installing a new OS to improve security?

• A. Applying OS updates and patches
• B. Installing games
• C. Changing wallpaper
• D. Defragmenting drive

Answer: (A)

After installing a new OS, the most important security action is to apply updates and patches. These updates regularly fix known vulnerabilities, close attack vectors, and sometimes improve default configurations to be more secure. Keeping the system current reduces the chance that attackers can exploit unpatched flaws and creates a safer foundation for additional protections like a firewall and antivirus. Installing games, changing wallpaper, or defragmenting the drive don’t directly enhance security. Games can introduce software from untrusted sources, changing wallpaper has no impact on security, and defragmenting is about performance and file organization rather than safeguarding the system from threats.
