How to Force a System Restore
One of the most useful features included by default with Microsoft Windows operating systems is the System Restore tool. System Restore takes periodic “snapshots” of the specified drives and partitions on the computer, recording installed software, settings and data installed on the computer at that point in time. These snapshots are called “Restore Points.” Using the System Restore tool in Windows, you can select one of the previously created Restore Points and effectively “roll back” the computer to the point in time when the Restore Point was created.
Click the Windows “Start” orb and then click the “Control Panel” option.
Click the “System and Security” option in the Control Panel interface.
Click the “Action Center” link in the System and Security page.
Click the “Recovery” icon located at the bottom right of the Action Center page.
Click the “Open System Restore” button and then click “Next.”
Click the Restore Point to use for the restoration process. Check the check box in front of the option “Show More Restore Points” to show older points, if necessary. Click the “Next” button.
Click the “Finish” button to start the restoration process. A confirmation dialog box will appear noting the restore point chosen and verifying that the restoration process is about to begin.
Click “OK.” The restoration process will begin and may take some time to complete. When finished, the computer will boot up into normal Windows mode.
