What is typically performed as one of the first steps after installing a new operating system?

• A. Applying OS updates and patches
• B. Defragmenting the drive
• C. Enabling USB autorun
• D. Installing games

Answer: (A)

After a fresh OS install, the most important first step is to apply updates and patches. These fixes come from the vendor to close security holes, fix bugs, and improve compatibility with hardware and software. Running the OS’s update tool brings the system to the latest build, which reduces the risk of malware exploiting known vulnerabilities and helps ensure drivers and core components work reliably. This updates process often requires a reboot to complete, but it’s worth doing before you connect to networks or install additional software, so the system starts secure and stable.

Defragmenting the drive isn’t typically a concern right after install, especially on modern systems and solid-state drives, since the OS already manages storage optimization and defragmentation is not usually needed immediately. Enabling USB autorun poses a security risk, so it’s generally left disabled by default to prevent automatic execution of software from USB devices. Installing games is something you do later after the system is secured and configured; it doesn’t address the critical need to secure and stabilize the fresh installation.
