The Windows 7 system requires a digital signature for the driver. Otherwise, it cannot be installed and used normally. But we sometimes need to use a driver without a digital signature. What should I do? How to disable the driver signature forcing? Here is a description of the operation. Method, everyone can refer to.

Steps:

1. Click on Start in the lower left corner - Run

2. Enter "gpedit.msc" in the prompt box - press OK or Enter. Open the Local Group Policy Editor.

4. After the system is expanded, double-click the left button to expand the driver installation.

5, in the driver to install the corresponding right window, we found: device driver code signature, and left double click: device driver code signature

6, in the open device driver code signature window, we choose: Enabled, in the option drop-down box, there are: ignore, warning, block for selection.

Warning: Notify users of files that are not digitally signed and let the user decide whether to stop the installation or continue the installation and whether to allow the installation of files that are not digitally signed.
