Option 1: Backup Your System Using System Restore

System Restore works a lot like the Undo command in Microsoft Word. You can use System Restore to return to your previous driver version if you create a restore point prior to installing the driver. System Restore does not affect your personal data files (such as Microsoft Word documents, browsing history, drawings, favorites, or email) so you won't lose changes made to these files after the restore point is created.

Windows XP steps to create a restore point (before installing the new driver):

1. Click Start
2. Point to All Programs
3. Point to Accessories
4. Point to System Tools
5. Click System Restore
6. Click Create a restore point, and then click Next
7. Type a name to identify this restore point and click Create

To return to this restore point, from the same System Restore Wizard select Restore my computer to an earlier time. Then select the date you created the restore point from the calendar in the Select a Restore Point screen. All of the restore points you created and you computer created on the selected date are listed by name in the list box to the right of the calendar.

Windows Vista or Windows 7 steps to create a restore point (before installing the new driver):

4. In the left pane, click System Protection
