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:
