Class 10 · Chapter 2
This chapter is about keeping a computer healthy after a problem is fixed. You will check how a computer is doing with Task Manager, Resource Monitor and Event Viewer, and bring it back with Safe Mode, System Restore or a bootable USB. You will also see what BIOS and UEFI do at startup, how to get back deleted files, and which simple habits, like cleanups, updates, virus scans and good records, stop problems before they start.
