Start-Run (enter gpedit.msc)- OK or press Enter. Open the local group policy editor;

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

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

4. In the expanded item of the system, find: driver installation, and left-click: driver installation;

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

6. In the device-driven code signing window that opens, select Enable. In the drop-down box options, you can choose Warning, Blocking and Ignore.

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

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

8. The above method is a way for Windows7 system to disable driver signature enforcement. There are other methods, such as pressing F8 to enter the safe mode when booting, or disabling the driver signature enforcement, so I won't go into details here.
