Don't be afraid, this is something that windows gilds the lily. Just click OK to install. In XP system, sometimes when we install the driver, the system will check whether the driver has passed the signature authentication of Microsoft. If it fails to pass the authentication, the system will pop up a warning prompt. In fact, many drivers themselves are not wrong. This hint is just superfluous. How do we turn off this prompt?

Right-click my computer-Properties-Hardware-Driver Signature, and then select Ignore in the pop-up dialog box, that is, install the software without my permission. Note that the check box in front of the option "Make this operation the default application of the system" should be selected, and it will take effect after "OK" exits. When we install the driver again in the future, we will never see the XP warning dialog box again.
