Win8.1 disables the mandatory driver signature setting tutorial

Update error:

1, the old device driver has not been updated on the official website, the official website has Vista driver ( An inf file), once used in the Windows7 (64-bit) operating system, ntx86 can be changed to ntamd64, and can pass the test! But in the Windows 8.1 operating system, it shows that the third-party INF does not contain digital signature information. An error message, so I don't want to continue the installation.

2. The digital authentication driver is a Windows Lab (WHQL)-certified driver.

Of course, it is impossible to cover the old equipment, and the error message will be inevitable.
