Microsoft System Restore

Microsoft Windows 7 includes a feature that enables you to restore your computer configuration to a configuration that was in use before the current software problem existed. The feature does this by creating a restore point where it records the computer settings at that time and date.

When a new program is installed, the operating system automatically creates a restore point before it adds the new software. You can also set restore points manually.

If you experience a problem that you think may be due to software on your computer, use System Restore to return the computer to a previous restore point.

NOTE: Always use this System Restore procedure before you use the system recovery program.

To start a System Restore:

1Close all open programs.

2Click the Start button, right-click Computer, and then click Properties.

3Choose System protection, System Restore, and then click Next.

4Follow the onscreen instructions.

To manually add restore points:

1Close all open programs.

2Click the Start button, right-click Computer, and then click Properties.

3Click System protection.

4Under Protection Settings, select the disk for which you want to create a restore point.

5Click Create.
