Run Unsigned drivers in Vista 64-bit

Hope this hasnt been posted before!

WARNING: I havent tested this myself, but I plan on installing 64bit soon.

I came across this little command to disable the integrity checks (DOS Prompt):

"bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS"

Now go update your video drivers in absolute freedom!!!

 

I read somewhere that this no longer worked after applying some Vista updates. So might be worth testing it.

 

I can confirm that does not work anymore. Some patch a while ago stopped it. So far the only solution seems to be Booting with F8 every time and choose to disable digital driver signing.

 

This function will no longer work if you have vista updates- KB932596, KB938979, KB938194, KB941649, KB943078 installed. If you want to use unsigned drivers then you must de-select these updates when windows updates offers them to you. What thomaskc says is true but you will need to press F8 every time you boot and select "Disable Driver Signature Enforcement" which will only turn off the driver integrity check for that boot alone. There is a rumor that microsoft is planning to include these updates in SP1(x64) when it is released which will mean the end of using unsigned drivers in vista x64.

I have been thinking myself about using 64bit but because RMClock doesn't have a signed 64bit RTcore driver it is holding me back. Everything else I have researched and sorted out already. It is unfortunate that microsoft forces driver signing on vista x64. Yes it has its positives as it means a more stable system; but the downside is freeware programs that use drivers will not work because inorder to get a driver signed by microsoft you have to pay money.

 

On the MS Connect site you can register for a driver certification to sign your own, and it's free.

I found this which contains links to the relevant sites.

 

I run vista x64 with sp1 rc1 right now succesfully ! runs like a charm! I DO have to boot with F8 every time, but when that has become a habbit, everything is just great.

 

You should not have to hit extra keys on startup just to run the hardware you purchased the way you want to. Screw Vista and its driver checks, I'm sure hackers have already managed to get around this.

 

This is exactly what I was thinking when I was considering 64-bit vista. So I will just stick with 32-bit.

 

Well its a bummer this doesnt work, i dont know who microsoft thinks they are when only allowing signed drivers....
