Using System Restore in Visual C#.NET

Create QR Code in Visual C#.NET Using System Restore

Before changing system settings during troubleshooting, create a restore point. If a problem occurs, you can undo the negative effects of diagnostic and troubleshooting changes by reverting to a previous state. The following items illustrate situations where System Restore can help you recover from problems that might occur. Uninstalling incompatible software does not resolve the problem If the problem persists after uninstalling an application, you can use System Restore to return the system to a state before you installed the new software. Updating a device driver causes system instability During the week, you decide to update drivers for five devices. At the end of the week, you find that your system is unstable. If you are not sure which driver is causing conflicts, you can revert your system configuration by using a restore point created the previous week. Downloading content causes a problem You visit a Web site and download a program or control that causes problems. By using System Restore, you can undo the negative effects of downloaded software. Identifying a problem is not possible If you are unable to diagnose a problem but know approximately when the problem started, you can use System Restore to restore your system to a state when it was performing normally. Undoing a System Restore operation that does not solve the problem You can undo the effects of the last restore point used by selecting Undo my last restore at the System Restore screen that appears after a restore operation. You can optionally rerun System Restore and select another restore point.

Part VI:

To restore the system by using a restore point 1. Click Help and Support Center, and under Pick a task, click Undo changes to your computer with System Restore. 2. On the Welcome to System Restore screen, click Restore my computer to an earlier time, and then click Next. 3. Select a restore point on the Select a Restore Point screen, and then click Next. 4. At the Confirm Restore Point screen, click Next. When you choose a specific restore point, System Restore examines the System Restore change logs. These logs contain information that enables System Restore to create a restore map, which outlines how to revert the system to the selected system state. System Restore processes the restore map, reverses file and registry changes (by using information stored in the restore point), and then restarts the computer. If you are not satisfied with the results, you can rerun System Restore and select another restore point, or you can select the Undo my last restoration option available on the Welcome to System Restore screen. Note

If you know the specific driver causing the problem, rolling back drivers might be a preferred troubleshooting option because it limits changes to reverting a driver for one device. For more information about rolling back drivers, see Device Driver Roll Back earlier in this appendix.

To create a restore point manually 1. Start System Restore. 2. Click Create a restore point, and then click Next. 3. At the Create a Restore Point screen, type a description for the restore point in the Restore point description line. 4. Click the Create button.

You can use the Control Panel to configure and manage your system restore settings. To configure System Restore settings by using Control Panel 1. In Control Panel, open System. 2. In the System Properties dialog box, click the System Restore tab. 3. System Restore is enabled by default. If you have disabled System Restore, you can enable it by clearing the Turn off System Restore check box. You can also specify the amount of hard disk space that System Restore uses for data archives by adjusting the Disk space to use slider for each volume.
