Windows Vista System Restore:
You can restore your PC back to a known working configuration by using Windows System Restore.
Available in Windows Vista Premium, Business, Ultimate, and Enterprise editions, Windows Restore is an image-based backup tool that will help you restore you computer configuration to an earlier point without losing data.
This is ideal if your computer is not operating well because of a configuration change, a problem with an application, or the introduction of viruses or other unwanted software. By restoring to an earlier point—a point before your computer began displaying problems—you may be able to easily resolve the problems. (Note: Applications that have been installed since the restore point will be removed.)
Steps:
- Click on Start menu and type in ‘restore’ into the Search menu search box. You'll immediately see ‘System Restore’ at the top of the start menu under ‘Programs’:

- Open the System Restore program and select either 'Recommended restore' or 'Choose a different restore point.'
- Recommended restore: Select this option to undo the most recent update or software installation if you think it is causing problems.
- Choose a different restore point: If you think the cause of you computer problems comes from a previous installation, select this option to see a list of restore points to choose from.
- Choose a restore point option and click ‘Next.’
- To apply the changes click ‘Finish’ to confirm and restart your computer to roll the system back.
