During a recent visit to the Windows Update web site, I was tempted by a driver update listed in the "Hardware, Optional" category. I installed the driver and restarted Windows, and now the device no longer works. Did I do something wrong, or did I just fall for a trap?
While Microsoft has the right intentions, it doesn't always have the right drivers. In theory, Windows Update should only suggest a driver upgrade if your device is already using a Microsoft driver, but sometimes it oversteps its bounds. Fortunately, Windows is prepared for this!
Open the Device Manager (go to Start --> Run and type devmgmt.msc ), find your device in the tree, right-click it, and select Properties. Choose the Driver tab and click the Roll Back Driver button. If all goes well, Windows should remove the new driver and reinstate the old functional driver automatically.
Sometimes this doesn't work, though. If Windows complains that it can't roll back the driver, or if the device still doesn't work after the old driver was supposedly restored, your best bet is to dig through your disks and install the original driver that came with your gadget. Better yet, visit the manufacturer's web site, download the latest driver for your model, and install it over the one already on your system.
