Sometimes when we try to install driver in Windows 8, we receive error messages which tell us either "A digitally signed driver is required", whether "The driver installation failed". While on previous Windows systems no such requirements and/or errors were encountered, Windows 8 only tries to impose them on users installing digitally signed drivers, and although this could ultimately mean a good thing (more security and the certainty that they are not installed the wrong drivers for the system), can become a problem when trying to connect new devices to the system (such as certain Android devices), and Windows does not want to install the drivers for them for the reasons specified above. And yet there is a way that Windows 8 users can install unsigned drivers for strong devices, and the solution is in the instructions below.
