How to Disable Enforced Driver signing in Vista x64

Prince_Link · Feb 11, 2007, 05:33 AM

Windows Vista x64 originally allowed you to disable enforced driver signing in the bootloader, but this was removed in RC2, and not present in RTM

this meant you have to go into the boot menu ( f8 ) every time you wanted to run an unsigned driver.

a new way has been found to disable driver signing permanently

open up a command prompt (usually start > run > cmd - hit enter)

in the command prompt enter the following

Code:

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS

Am I missing something, or can't you just click on "Install anyway" when you go to install an unsigned driver?

Not on Vista64 it's different to the 32 bit system. WHQL signed drivers are a requirement of the 64 bit OS.

The command prompt version is the best way to go about it.

and x64 is damn picky when it comes to anything. It just won't accept any garbage period.

These seem to be installed and running fine without doing anything special to install them:

driver enforcement doesn't seem to affect all drivers for some reason.

It didn''t affect realtek ac'97 drivers at least, good to know tho.

i've never seen a AC97 driver that wasn't signed.
