If you've installed a new driver that is causing problems on your computer, you can easily roll back to the prior version of the driver with a few simple steps.

First you'll need to open Device Manager. The easiest way is to just type device manager into the start menu search box, but you could also go through the control panel if you choose.

Once you have it open, browse down to the problem device, right-click and choose Properties.

Now click on the Driver tab, and then click the Roll Back Driver button.

You'll get a prompt telling you that you don't want to do it, but go ahead anyway. You can always click the Update Driver button to get the latest version again.

As you can see from my choice of device, the latest touchpad driver was causing problems for me, so I rolled it back.
