CompTIA A+ 220-1202 Practice Question

Performing a repair installation of Windows is the correct step here as it attempts to replace missing or corrupt system files while preserving personal data and installed applications. This method restores the system to a functional state without requiring a complete reinstallation, which would lead to data loss.

Other options, such as running a virus scan, may not address the core issue of missing files, and merely trying to reboot or reinstall applications will not resolve the underlying operating system problem.
