Windows7 system needs a digital signature to use the driver, otherwise it will not work normally, but sometimes it needs a driver without a digital signature. At this point, it is necessary to disable driver signature enforcement. The specific steps are as follows:

Methods of disabling driver signature implementation in 1 and Windows7 systems

begin

-

Run (enter gpedit.msc)

Confirm or enter. Open the local group policy editor;

2. In the opened local group policy editor window, we find: user configuration.

-

Manage templates;

3. In the expansion item of the management template, find: system, expand;

4. In the extension of the system, we find: driver installation, and then left-click: driver installation;

5. In the right window corresponding to the driver installation, we find: code signing of the device driver, left key: code signing of the device driver;

6. In the opened device driver code signing window, we select Enabled, and there are Warning, Blocking and Ignore in the drop-down box of options.

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

Block: Indicates that the system refuses to install files that are not digitally signed.

Ignore: Command the system to continue the installation (including installing files that are not digitally signed).

If we want to install a driver file without digital signature, we can choose: Ignore, and then click: OK;

7. After the driver installation is completed, it is suggested to set the item just set to ignore as warning (default setting) to enhance the security of the system.
