At present, all PCs have 4G or 8G memory, but unfortunately, 32-bit systems cannot support more than 4G memory. Most of my friends have changed into the cool and fresh 64-bit win8. 1 system, and because of the security of the system, it is restricted to install drivers without authentication signature. However, it is impossible for most small programs that use driver files to have digital signature authentication, so many users can't successfully use the previous driver on 64-bit win8. 1, so Bian Xiao will teach you how to disable the driver's mandatory signature in win8. 1!

Win8. 1 The system disables driver signature enforcement.

After booting, press F8 in the login waiting interface to enter the advanced startup item of Windows operating system. We will find that the last item is to disable driver signature enforcement. According to this item, you can use the driver without digital signature when you enter the system!

Click here "Restart immediately" to directly enter the advanced startup interface!

Although the above method is simple, it can only be set when the computer is turned on and restored to its original state after restarting the computer. Here is a once-and-for-all method, which is to use the command to turn off the forced driver signature: bcdedit.exe-setloadoptionsddisable _ integrity _ checks.

1. Open the CMD command line as an administrator;

2. Then enter the above command, restart the computer after completion, and you can use the driver without digital signature on the 64-bit win8. 1 system at any time.

Note: this operation also reduces the safety factor of the system, so it is not recommended to shut down all the time, and it is not recommended for inexperienced users.
