System Restore is a system recovery feature of Windows that creates snapshots, or restore points, of the state of your computer at various intervals or before you perform a certain task. These restore points can then be used to restore your computer back to the state it was in when they were taken. When these restore points are created, and restored, the only files affected are the Windows Registry, programs, and system files. Your data such as spreadsheets, documents, images, and music remain untouched between restores.
You may be wondering why you would want to restore your computer to a previous point. The reason being that there comes a time in every computer user's life that they install a new program, install a new driver, or just turn on the computer and find it no longer works as it did the day before. You have no idea why, can't resolve the problems, and are left with two options. You can either backup your data, reinstall the operating system, and then reinstall all your applications or you can restore your computer to a previous snapshot in the hopes that the problems will now be gone. By using System Restore to restore your computer to a previously known working state you can save considerable time or money compared to reinstalling the entire computer.
System Restore points are automatically created when the following actions occur:
In order for System Restore to work you must have 300 MB of free space for each hard disk that System Restore is monitoring. System Restore will also use up to 15% of the disk space on each disk that it monitors. As hard drive space runs out, older restore points will be deleted as newer ones are created. It is also important to point out that you must be logged in as an Administrator in order to use System Restore. Now that you understand the basics of System Restore, you should continue to the next section to learn how to use it.
In the case of a problem on your computer that cannot be solved by normal means, you can restore your computer back to a previous working state. To do this you need to start System Restore so that you can choose the restore point to restore. If you are currently having problems starting Windows Vista, you can use System Restore from the Windows Recovery Environment. Instructions on how to do this can be found in this tutorial: Using System Restore from the Vista Windows Recovery Environment.
If you can log into Windows Vista, then you should follow these steps.
You will now be at the System Restore screen as shown below in Figure 1. From this screen you can specify the restore point that you would like to restore.
Figure 1. System Restore Screen
By default, Vista will already have selected the Recommended restore option. This restore point is one was made after a new program, driver, or update was installed. If you would like to use this restore point, you can click on the Next button to start the restore process. On the other hand, if there is a more recent restore point that you would like to restore you should select Choose a different restore point and press the Next button. This will bring you to a screen, as shown in Figure 2, that contains a listing of all the available restore points that you can restore to.
Figure 2. List of available restore points
You should select the restore point that you would like to restore and press the Next button to start the restore process. Vista will display a Window showing your selected restore point and asking you to confirm that this is the one you would like to restore.
Figure 3. Confirm the selected restore point
If you would like to select a different restore point press the Back button. Otherwise you can press the Cancel button to exit System Restore or the Finish button to begin the restore process. If you selected Finish, Vista will display a second prompt asking you to confirm that you would like to continue the restore.
Figure 4. Second Confirmation
If you are sure you want to do the restore, then press the Yes button. Vista will now log you off of the computer and start the System Restore process as shown in Figure 5 below.
Figure 5. Restoring a restore point
When the restore has been completed, you computer will be restarted and when Vista boots back up it will be restored to its previous state. When you log in to Vista for the first time after the restore, you will see a message showing that the restore was successful.
Figure 6. System restore was successful
If there are any problems with your computer due to the last restore, you can revert back to your previous settings by going back into the System Restore Utility and selecting the Undo System Restore option and pressing the Next button.
Figure 7. Undo the last System Restore
Your computer should now be working properly again.
As said previously, it is also possible to create manual restore points as needed. Popular reasons to create manual restore points are when you have your computer set up perfectly and would like to save the state in the case of problems in the future. To create a manual restore point you need to follow these steps:
You will now be at the System Protection tab in the System control panel. This tab allows you to enable and disable System Restore as well as make new manual restore points.
Figure 8. System Protection tab
To create the manual restore point you should click on the Create button. When you press this button a prompt will appear asking you to provide a title for this manual restore point.
Figure 9. Enter title for manual restore point
Type in a title for the manual restore point and press the Create button. Vista will now create a manual restore point, and when completed, display a notice saying that it was created successfully.
Figure 10. Manual restore point was created
Now that you have completed making the manual restore point you can close the System window.
It is advised that you do not turn off System Restore unless you have specific need to do so.
WARNING: By disabling system restore you will delete all stored restore points and shadow copies of documents on your computer.
To disable System Restore you would follow these steps:
System Restore is now disabled on your computer.
By default System Restore is enabled on Windows Vista computers so you will only need to enable it if you have previously disabled it. To enable System Restore do the following:
System Restore is now enabled on your computer.
There are two safe ways to delete restore points stored on your computer. These ways are described below:
Turn off System Restore - When you turn off System Restore, all previously created restore points will be deleted.
System Restore runs out of storage space - If System Restore runs out of allocated space it will delete the older restore point in order to create free space in which to create the new restore point.
If you are the owner Windows Vista Business, Ultimate, or Enterprise then you also have a feature called Shadow Copy available to you. Shadow Copy is a feature integrated into System Restore that makes copies of your documents when a restore point is created. You can then use these shadow copies to restore these files at a later date if they have been accidentally deleted or altered in some way. Since Shadow Copy is integrated into System Restore, if System Restore is disabled you will not be able to use Shadow Copy.
To use Shadow Copy to restore a particular file to a previous state you would right-click on the file and select the Restore previous versions option as shown in Figure 8 below.
Figure 12. Restore Previous Versions
This will bring up a new screen showing the previous versions of the file that are available to restore as shown in Figure 9 below.
Figure 13. List of previous versions
When you select a version from the list you have three options.
The interesting this about this feature is it does not work only on files. You can also use this feature to restore folders, and all of its contents, that were deleted. To restore a previous version of a folder you would do the following.
When restoring folders, if you only wish to restore a particular file in the folder Shadow Copy, you should select the Open option to open the Shadow Copy folder and then copy the particular Shadow Copy files out of it that you need. As you can see Shadow Copy is a powerful way to keep your data safe and to have backups available in the case of accidental deletions or irreversible changes.
The System Restore tool is a powerful feature that can be used to keep your computer operating properly. Now when you run into a problem that cannot be resolved normally, you can use System Restore to restore your computer to a previous known working state. Even more powerful is the ability to use system restore from the Windows Recovery Environment when you can't properly boot up into Windows. This allows you a second chance to get your computer operating as it should without having to do a time consuming and possibly expensive reinstall.
