When something goes terribly wrong with your system you can restore it to a previous state and you will be able to use it again. System Restore is a feature that allows users to restore their system to a previous state. It offers a way to undo all the changes in the system files, registry keys, installed programs, etc, to a previous state, without affecting personal files such as documents, photos or e-mails. It was first implemented in Windows Me and since then it was included in both Windows XP and Windows Vista.
There are several ways to find System Restore. The easiest is to type “system restore” in the Start Menu search field and press Enter or click on the search result.The main System Restore window will open. You have two options: to restore your system to a previous restore point or to create a new restore point.To restore your system to a previous state you can use the recommended restore point or you can choose a different one. The Recommended restoreoption will restore your system to the most recent restore point.
If you select the second option, after you press the Next button, you will see a list of available restore points. Select the one you prefer and press the Next button once again.
Now you are asked to confirm your restore point. Click the Finish button and System Restore will restart your computer to apply the necessary changes.
