How to Fix Drivers in Windows 7

When you have a hardware device that does not work, such as a CD-drive, it is likely the result of a driver that is not working properly. A driver that is not working properly is generally caused by the driver being out of date. Fortunately, the Windows 7 operating system includes a tool that allows you to update any driver automatically. You must be connected to the Internet for this tool to work properly.
