Windows XP includes a feature to prevent unsigned drivers from installing on our machine. This is the case to most beta drivers that I install for my graphics card. It is very distracting to see the message that this driver is not signed and it is not secure enough. I found a way to get rid of that message permanently.

Open Control Panel | System.

On the Hardware tab, click Driver Signing.

Under File signature verification, click:

• Ignore to allow all device drivers to be installed on this computer, regardless of whether they have a digital signature.
• Warn to display a warning message whenever an installation program attempts to install a device driver without a digital signature. This is the default behavior for Windows.
• Block to prevent an installation program from installing device drivers without a digital signature.

Note: Windows device drivers and operating system files have been digitally signed by Microsoft to ensure their quality. A Microsoft digital signature is your assurance that a particular file has met a certain level of testing, and that the file has not been altered or overwritten by another program’s installation process.
