The Roll Back Driver feature enables you to replace a device driver by using a previously installed version. You can use this feature if you have installed a new device driver that causes your computer to be unstable. When you use the Roll Back Driver feature, you can restore (or roll back) the previous device driver, and continue to use the computer.
To use the Roll Back Feature:
Start Device Manager.
Double-click the device for which you want to restore the driver.
Click the Driver tab, and then click the Roll Back Driver button.
