Removing Restore Points and Previous Versions of Files

The Disk Cleanup utility was introduced in Chapter 4, “ Disk Management.” It removes temporary files, empties the Recycle Bin, and removes a variety of system files and other items that you no longer need. After you scan your disk using the Disk Cleanup utility, you can click the More Options tab and click the Clean up button in the System Restore and Shadow Copies section to delete all but the most recent restore point on the disk, including previous versions of files.

Cram Quiz Answers

1. A is correct. A System Image Backup, sometimes referred to as the Complete PC Backup, is a copy of the system drives required for Windows to run and is one of the fastest ways to restore your hard disk. It can also include additional drives. Answer B is incorrect because System Restore only backs up System files, not data files. Answer C is incorrect because the Previous Versions of Files only backs up data files, not system files. Answer D is incorrect because System Configuration is a troubleshooting tool for boot problems, not a backup tool.

2. D is correct. System Restore backs up the registry, DLL cache folder, user pro- files, COM+ and WMI information, IIS metabase, and certain monitored files. It does not back up data files.

Review Question Answers

1. Answer D is correct. If you open System Configuration, select the Boot tab, and select OS boot information, it shows you the driver names that are loaded during startup. Answers A, B, and C are incorrect because those options do not provide that information. Base video starts the monitor with a 640 × 480 resolution. The Boot log generates a log that could be accessed after it boots. The No GUI boot checkbox starts in with a command prompt.

2. Answer B is correct. The two places to look for a history of problems are the Event Viewer and the Reliability Monitor. Answer A is incorrect because Performance Monitor is used to measure performance. Answer C is incorrect because the Data Collector Set is used to group counters together so that you can call them up as needed or schedule them to be measured. Answer D is incorrect because the Resource Overview tool shows the performance of the major subcomponents, including CPU, memory, network, and disk.

3. Answer B is correct. Because you cannot start the computer, there might be a problem with the startup files. Therefore, you need to run the Startup Repair tool. Answer A is incorrect because you don’t want to go back to an old operating system. Answers C and D are incorrect because you cannot start Windows to get to the Software Explorer or msconfig.exe (System Configuration tool).

CHAPTER 16: Backups and System Recovery

4. Answer D is correct. If you load a driver and your machine does not boot properly, you can access the advanced boot menu and try Last Known Good Configuration. Answer A is incorrect because you cannot access Windows to use SYSEDIT. Answer B is incorrect because reinstalling Windows takes a lot of effort and might not correct the problem. Answer C is incorrect because there is no emergency repair disk to use with Windows 7; everything is included with the Windows 7 installation disk.

5. Answer C is correct. If you cannot boot the computer, the next logical step is to boot Windows in Safe Mode. In Safe Mode, minimum drivers are loaded. Answer

A is not a viable option because most systems do not have another hard drive with another version of Windows. This solution can also become very messy. Answer B is incorrect because you cannot use DOS to correct most Windows problems. Answer D is incorrect because you need to first load Windows before you can use the System Configuration tool.

6. Answer B is correct. The system configuration tool is a diagnostic tool that can help you isolate startup programs and services that prevent Windows from boot- ing. Answer A is incorrect because Device Manager manages devices, not services. Answer C is incorrect because there is no such thing as the boot.ini tool or file in Windows 7. Answer D is used to revert back when you load a driver, service, or program that prevents Windows from loading. It does not disable a service.

7. Answer D is correct. System Restore can reconfigure Windows to its original settings before the problem occurred. Answer A is incorrect because this is not a device problem. Answer B is incorrect because you can load Windows, so you don’t need to use Safe Mode. Answer C is incorrect because if you log in to Windows successfully, you overwrite the Last Known Good Configuration.
