Driver Signing in x64
April 28th, 2007
One of the more annoying components in Vista x64 is the need for signed drivers. This hinders the use of many freeware applications out there (even though they come with an x64 driver) just because the driver isn’t digitally signed. About a month ago I ran into a piece of software I had to use, but alas, no signed drivers. So I set out on a quest to figure out how to permanently disable the driver signing checks in Vista x64. And guess what? I found it 
.
�Here’s how to get it done:
- Open an elevated command prompt
- type “bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS” without the quotes (and no the DD is not a typo).
- Reboot and enjoy being able to use unsigned drivers in Vista x64.
- Remember who told you about this first

doesn’t work for me i get – “The specified command line is not valid. Run “bcdedit /?” for command line assistance.”
Are you sure this works on RTM? I thought the option to disable was only on RC and beta versions. Anyway, I too run an Admin CMD and get the invalid command line response…
Sorry guys, typoed the command, it should be /set instead of plain set. Changed it in the main post.
I think you will find this is only for the next boot. I suggest using this in a Scheduled event at logoff time…
I entered this command almost a month ago now on my laptop and it has remained persistent on every reboot.
Thank you very much!
Brilliant – knew someone will get the answer at some stage. Thanks Chris123NT !! Tried it and it persists – now I can make some progress on my USB Serial port testing !!!
Doesn’t work for me. Crystal CPUID still doesn’t work properly
Any chance to use NEATRECEIPTS on a MAC as a simple scanner?
So is there any possible work-a-round for this unsigned driver thing?
Maybe something like VistaBoot Pro could incorporate something? dunno….
Typical of Microsoft to make things difficult for their customers…
Nice trick, i will try it to test creative beta drivers on Vista64.
But im curious.. what would be the command to revert this and re-enable driver signing checks?
Thanks for your help
ADSTECH DVD Express DX@ has beta drivers on their website. They wll not install on Vista Business X64 no matter which hads I try.
There is a very quick and easy fix that people overlook all the time. Reboot, hit F8 just before the green bar starts on the screen, and you’ll get a list of options, safe mode etc. Last one enables you to disable driver signing requirements. Job done.
I keep my PC on all the time so it’s no big deal, but I can see how this would annoy you if you reboot every day, but it does work if you remember to do it each time!
And for the record, the latest patches did disable the bcedit hack.
This doesn’t work, and I’m so sick of people claiming to have it permanently disabled, when clearly Microsoft, have just made more useless decision regarding there customers requirements.
But i repeat this METHOD does not and will not do anything than waste your time.
thank you for your help….It gives me more idea…
Try This Program, i am using it Since Vista released .. and i used it specially for ATT .
with this tool you can sign any Driver you want.
Just Read the Help file and everything will goes fine.

I made a automatic script to test sign drivers using microsoft’s signing tool. To use download, unzip and then put the drivers you wish to sign in the files driver folder. Run the program it automatically
Creates a certificate and signs the drivers in the driver folder. Then all you have to do is over write your unsigned drivers and your done.

Did this about 2 days after I got my laptop over 9 moths ago, and have never had a problem. Just checked and it was still enabled with a completely patched vista x64 business.
