How to roll back a faulty Windows Update

When the fix doesn't fix

QUESTION I'm trying to start up a C-Media AC 97 audio device as downloaded from Windows Update. I've got the device enabled as advised by the Startup menu, but it doesn't start and I now have no sound on my PC. The computer is an Advent 7012 running Windows XP Service Pack 3. John Levis

HELPROOM ANSWER Drivers distributed by Windows Update have a track record of causing problems.

On computers from larger manufacturers such as Dell and HP, components are often integrated within their own motherboards and are altered to suit each model.

Your best bet is to download and install the drivers from the PC manufacturer's support site, or roll back the faulty driver installed by Microsoft to the previous working version. To do this, right-click My Computer and choose Manage, Device Manager. Expand 'Sound, video and game controllers', then locate and double-click your sound card. In the Properties box that pops up, select the drivers tab and then click 'Roll back driver'. This will replace the driver with the earlier working version.

If this doesn't work, you can also use System Restore to roll back your computer to before the problem occurred. See How to create and manage System Restore points.
