Before you install a driver from a disc, check the info that comes with it to be sure it supports your current version of Windows. You can also search for new drivers on the manufacturer's website.

We recommend that you don't install unsigned or changed drivers. A digitally signed driver includes a digital signature, which is an electronic security mark that indicates the publisher of software and whether someone has tampered with it since it was signed. If a driver has been signed by a publisher that has verified its identity with a certification authority, you can be confident that the driver comes from that publisher and hasn't been changed.

If you see any of the following notifications when you're installing a driver, you should stop the installation and go to your device manufacturer's website to get a digitally signed driver for your device. The driver doesn't have a digital signature or has been signed with a digital signature that wasn't verified by a certification authority.

You should only install this driver if you got it from the manufacturer's disc or from your system administrator. The driver hasn't been digitally signed by a verified publisher. The driver might have been changed to include malware that could harm your PC or steal info. In rare cases, legitimate publishers do change drivers after they've been digitally signed, but you should only install an unsigned driver if you got it from a device manufacturer's disc.

Unfortunately, there's no trustworthy source of info that indicates who has published an unsigned driver. Anyone can change the contents of an unsigned driver, and there's no way to know why it was changed.

Most manufacturers now digitally sign the drivers they create before releasing them to the public. A driver that lacks a valid digital signature, or has a signature that was changed after it was signed, can't be installed on bit versions of Windows. You'll only see this notification if you have a bit version of Windows and try to install such a driver on it. Windows 8.
