I want some help to turn of Driver Signature Enforcement permanently. I am having a Windows Vista system. It is actually a 64bit system. I was having some issue with windows in terms of performance so I formatted and install everything back again from scratch. After formatting I am trying to install a number of unsigned drivers on the same. But it does not looks to be working. What should I do here to fix the issue I am facing. I am unable to find any solution for the same.
