CHAPTER 17 707 Maintaining and Troubleshooting Windows In this chapter, you will learn how to • Maintain Windows • Optimize Windows • Troubleshoot Windows Every computer running a Windows operating system requires occasional optimiza- tion to keep the system running snappily, ongoing maintenance to make sure noth- ing goes wrong, and troubleshooting when the system doesn’t work correctly. Not that long ago, Windows had a bad rap as being difficult to maintain and challenging when troubleshooting problems. That’s no longer true. Microsoft used its decades of experience with operating systems to search for ways to make the tasks of maintain- ing and troubleshooting less onerous. They’ve done such a good job with the latest versions of Windows that, out of the box, they are easy to optimize and maintain, although troubleshooting and all operating systems share this is still a bit of a challenge. The chapter starts with maintenance and optimization, so let’s make sure you know what these two terms mean. Maintenance means jobs you do from time to time to keep Windows running well, such as running hard drive utilities. CompTIA sees optimization as jobs you do to your Windows system to make it better a good example is adding RAM. This chapter covers the standard maintenance and optimization activities per- formed on Windows and the tools techs use to perform them. The last part of this chapter dives into troubleshooting Windows, examining steps you can take to bring a system back from the brink of disaster. You’ll learn tech- niques for recovering a PC that won’t boot and a PC that almost boots into Windows but fails.

CompTIA A+Certification All-in-One Exam Guide 708 Essentials Maintaining Windows Maintaining Windows can be compared to maintaining a new automobile. Of course, a new automobile comes with a warranty, so most of us just take it to the dealer to get work done. In this case, you are the mechanic, so you need to think as an auto mechanic would think. First, an auto mechanic needs to apply recalls when the automaker finds a serious problem. For a PC tech, that means keeping the system patches announced by Microsoft up to date. You also need to check on the parts that wear down over time. On a car that might mean changing the oil or rotating the tires. In a Windows system that includes keeping the hard drive and Registry organized and uncluttered. Patches, Updates, and Service Packs Updating Windows has been an important, but often neglected, task for computer users. Typically, Microsoft finds and corrects problems with its software and releases patches on the second Tuesday of every month. Sadly, because earlier versions of Win- dows let users decide when, if ever, to update their computers, the net result could be disastrous. The Blaster worm hammered computers all over the world in the summer of 2003, causing thousands of computers to start rebooting spontaneously—no small feat for a tiny piece of programming! Blaster exploited a flaw in Windows 2000/XP and

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
