I'm looking to disable the mandatory driver signature enforcement in Vista x64 Ultimate. I have partially gotten that to work, but there still some that occasionally refuse to install simply because they are unsigned. I'm not looking for a security lesson or "It's not a good idea" as I am aware of the intention of the "feature" and the possible consequences of unsigned drivers...that being said, I've tried disabling it in gpedit by:
1) User Configuration -> Administrative Templates -> System -> Driver Installation
enabling the "Code signing for drivers"
and then choosing "Ignore"
2) bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS
3) bcdedit.exe /set nointegritychecks ON
While these methods do allow me to install many unsigned drivers, some still are blocked.
For responses to this question, I'm only looking for alternate methods that you have successfully used. Thanks.
