Chapter 21: Getting Help and Handling Advanced Support Issues
If you cannot start your computer, you can try to recover the computer using a
restore point by following these steps:
1. Insert the Windows Vista installation disc and then restart the computer. When
prompted, press a key to boot from the installation disc. Setup will then load the
operating system from the disc.
2. When prompted, choose your language settings and then click Next. On the
installation screen, do not click “Install now.” Instead, click the “Repair your
computer” link in the lower-left corner of the screen.
3. In the System Recovery Options dialog box, select the operating system to repair
and then click Next.
4. In the System Recovery Options dialog box, choose System Restore. Follow the
prompts to recover the system using the selected recovery tool.
Restoring Previous Versions of Files
Windows Vista tracks changes in files and folders using Previous Versions. When
you configure System Restore for a disk, System Restore creates previous versions of

files and folders automatically as part of restore points. Any personal file or folder
that was modified since the last restore point is saved and made available as a previ-
ous version.
Previous versions are created for pictures, music, videos, email, docu-
ments, and other types of personal files. Previous versions are not cre-
ated for files and folders that the operating system uses.
You can use previous versions of files to restore files that were inadvertently changed,
deleted, or damaged. While System Restore creates previous versions daily for all
drives being monitored by System Restore, only those versions of files that are actu-
ally different from the current version are stored as previous versions. You can enable
or disable previous versions by enabling or disabling System Restore on a particular
drive.
Accessing previous versions of files and folders is a snap. To view previous versions
of a file or folder, right-click the file or folder and then select “Restore previous ver-
sions.” This opens the file or folder’s Properties dialog box to the Previous Versions
tab. Your computer will then search the available restore points for previous ver-
sions of the selected folder or file. When previous versions are available, the Previ-
ous Versions tab lists the previous versions of the file or folder by name and date.
Select the previous version you want to work with and then click:
Open to open the selected previous version
Copy to create a copy of the selected previous version
Restore to revert the file or folder to the selected previous version
If no previous versions are found, you’ll see a message stating this, as shown in
Figure 21-13. In this case, you may need to check your computer’s configuration to
ensure that System Restore is monitoring the related disk. Keep in mind that System
Restore does not create previous versions of offline files cached on your computer or
system files. For offline files, previous versions may be available on the server where
the file is stored. Changes made to system files are tracked as part of restore points,
and you must recover the computer to the restore point to go back to a previous
state.
If the folder in which the file was stored has been deleted, you must
open the Properties dialog box for the folder that contained the file or
folder that was deleted. Use this folder’s Previous Versions tab to
restore the folder and then access the file or folder to recover the previ-
ous version of the file you are looking for.
