As we know, the price of computer hardwares is getting lower and lower. In order to use the more advanced configurations, an increasing number of people apply 4GB or 8GB RAM in their computers. Moreover, most people change their operating system to Windows 8.1 (64 bit), because 32 bit system cannot support memory which is more than 4GB. However, taking system security into consideration, the 64-bit version of Windows 8.1 limits the installation of uncertified drivers. Whereas, most small programs which use driver files do not have digital signature authentication, including phone drivers. Does it mean that we cannot use the drivers we applied before on the Windows 8.1 of 64 bit? No, we can solve the problem by disabling driver signature enforcement in Windows 8 and 8.1.
Video guide on how to disable/enable driver signature enforcement in Win 8:
Step 1: Enter PC settings.
You can enter PC settings according to the following two procedures.
1. Open Charms Menu by simultaneously pressing WIN key (also referred to Windows logo key) and C key, and select Settings in it.
