    How do i revert this back?

  • Nick

    So can you post a few lines on how to undo the bcdedit commands and put things back to normal? I just read your guide on how to do this in group policy settings and that way looks to be much preferred.

  • http://dkj.me David

    Gregg the reverse commands are:

    bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
    bcdedit.exe -set TESTSIGNING OFF

    I followed the instructions and I get the bsod when the box shutsdown, not when it boots up. The bsod indicates a problem with usbhub.sys; although I never had a problem with that driver before installing libusb0. Any ideas what might be causing this? I notice in the Device Manager that the usb hub and ports show that they are using the libusb0 driver first and then the original usb driver. Why is that? I thought that the libusb0 driver would only be used by appliations that reference it.

  • zsolmanz

    Neither of these methods work for me, in Windows 7 RC :'(. I’ve only tried one unsigned program though, so it could be a different problem.

  • Morgan

    Can anyone confirm that this actually works please. I’m a bit of a noob and am too nervous to try this without confirmation first. On account that if something horrible happens I don’t have the knowledge to fix it!
    Really want to do this cos I need to install an app to “flash my bios”(!) and the driver is unsigned. Without this I can’t add 2x 1GB RAM as my MB is being difficult. I would be very grateful if someone could help me out please.

  • adrian

    This guide does NOT work for my Windows7 64 bit.

  • http://theweaselking.livejournal.com/ John

    Worked for me with Win7 64, except now Win7 says it’s in “test mode” in the bottom right of each of my desktop screens.

    Any way I can turn off that notification while still *having a graphics card* until Nvidia fixes their broken signature?

  • andy

    Not worked for me. Running Home Prem. Tried to install Tileproxy for FSX after a reboot and got the unassigned drivers prompt again. Have the test mode windows 7 build 7600 in bottom corner of screen.

  • Almost at Ubuntu…

    This whole signed driver thing is rediculous, Microsoft are basicaly penalizing anyone who is using 64bit machines.

    Why is 32bit so special, that signed drivers are not needed?

    & don’t give me the whole “security” talk, because for years we did okay without it. & now we need it?

    The companie’s should just say they are not going to pay for the signatures.

  • Rabi

    This did NOT work for me either. Now it shows ‘Test Mode’ at the bottom right corner but still I can NOT get rid of unsigned driver issue for my tv tuner sick issue – Pinnacle PCTV (80e) Mini Stick !
    Anybody facing same issue ?
    I am using the Pinnacle PCTV driver for Win 7 available from their website.

  • birtija

    I have the same issue: W7 Home premium 64bit + Not only Tv USB stick LV5H (hibrid).
    Drivers are instaled but W7 does not allow the use of them.

  • andrew

    I had the same problem with windows 7 enterprise 64 bit and an unsigned driver for my sound card (cmedia) pushing f8 to access the boot menu and disabling the driver signing checks on boot is the only method that is working so far, would love to know how to make this permanent, i have tried all the other methods mentioned here and none have worked for me. They worked before with the 7100 rc 64 bit so why not with the eneterprise edition ?

    is there a way to recompile an inf file designed for 32it windows to make it compatible for use in 64bit windows as thats the only thing stopping me from installing my monitors inf file and allowing to run 100Hz

    I cant get this to work on Windows 7 64 bit build 7100. Trying to get it to work so I can Install Pier Guardian…GRRR

    Tried this method on Win7 x64. Did not work at all. Just got the test mode watermark… nice!!!

    i want driver-signing disabled, perminanty because this is the only way I can get a ps3 pad to work with MotionInJoy, third party drivers.

    The method I’ve already tried is to press F8 during system boot (EVERYTIME!!)

    The last option allows driver signing to be disabled.

    … and hay presto!! working ps3 pad.

  • RichardD.

    TO me it says access denied? any1 know why?

  • chrissss

    Did you make sure you ran the command prompt as administrator?

  • jake`

    im using windows 7 7600 build, when i right clikc cmd i dont see run as admin ..

  • David

    This actually did not work. Both commands said they completed, I reboot. Tried to install the AC97 Win7 drivers it just loops “Windows Can’t verify the publisher of this driver software” with “don’t install this driver software” or “Install this driver software anyway” I press do it anyway, it loops.

    is there a command that really works?

  • Chris

    Does NOT work in RTM Windows 7 x64 build 7600

    To disable driver signing, you have to press F8 during boot every time.

  • arbitrary reader

    What Chris said ^

    None of these tactics work with build 7600. Shame on you Micblosoft…..

  • Rich

    Cannot disable with build 7600 (Home Premium). See the test mode watermark tho.

    Guessing you need enterprise or ultimate before you can develop / run unsigned drivers. Any ideas anybody for home prem?

    to turn them off do you need a reboot before they will not pop up an error?

    killertechtips worked for me except watermark. now found driver so any advice to go back!? thanks

  • franc

    microsoft wants with the driver digital signing to collect money from the chip producer.that is rape! and coercion.the idea of microsoft is send all chip producer to verisign to buy certificat and pay annual fee!the certificate can only be issued on windows server 2003 or 2008.that means microsoft wants sell its server.also give verisign some more millions USD because verisign is realy poor! speaker from microsoft said the digital signing is important to make it difficult for software producer pass virus etc to windows os.this assertion is exactly stupid because the virus comes to computer by email, sex pages, video and music pages and many freeware.but not through driver.the biggest problem for users is that the digital signed driver have expiry date.that as you know the producer offer 2 or 3 years warrnty.after the warranty is over, you may not be able to use the device because the digital signature is expired.the realy effective solution is that computer user collect signatures and make complaint against microsoft, same is chip producer, they all should collect signatures and make complaint against microsoft.

  • bballking18

    These two commands DOES NOT WORK on Win7 64 bit ultimate 7400 build..

    I assume the GPO trick will not work as well.. but will try tonight

  • dskfj

    Does NOT work. You suck.

  • Emm


    isn’t’ needed, it was eliminated by a security patch in vista, and I suppose the restriction is present in Win7 as well

    to revert back to the original state, assuming you haven’t messed with the options before:

    bcdedit /deletevalue loadoptions
    bcdedit /deletevalue testsigning

  • Emm

    OK, took me 20min to find and test a good alternative:

    Driver Signature Enforcement Overrider 1.3b from NGOHQ

    works as intended, it enables just that testsigning option but as was stated in the release notes, the drivers must have some sorts of signatures, even if those sigs are not verifies by Microsoft. This is for Win 7 7600 with updates.

    This is the reason the solution in the article isn’t working for a lot of you guyz.

    In DSEO, just use the Sign option for each file in turn that is a driver, so better know what you sing before you do it and better know all the files that need to be signed, not just some of them.

    Peace out!

    Any more ideas?

    Here’s how to undo this, if it doesn’t work for you:

    bcdedit.exe -deletevalue loadoptions
    bcdedit.exe -set TESTSIGNING off

  • Gutemberg

    You can just use F8 at boot time and select the option for temporary disable

    I would like to know why you smarty-pants people who offer this advice don’t give the following obvious information: THIS OPERATION DOES NOT WORK IF YOU ARE RUNNING WINDOWS 7 64 BIT!!!

  • Negleh

    If I found out who this dude is, I would beat the shit out of him. Now my devices don’t start after boot like the previous user said. I can’t use mouse, keyboard or any devices connected although they work before Windows boot. I tried to use the Windows 7 disc to restore, shit doesn’t work, I also used the install portion to get to Shift+F10 and run the command to off, doesn’t do a DAMN THING.

  • HonestClive

    This info is correct and will work with 64-bit if done correctly.

    The problem is Microsoft use driver signing to ensure the drivers you are about to load will work correctly and will not stuff up your PC. If you switch it off and load one of the billions of unsigned drivers out there that joe bloggs coded in their shed then thats the risk you take.

  • Dresden

    damn man what happened.. my pc exploded like a peanut bomb after doing this..

  • IT_guy

    I would not recommend this at all. I had problems with an unsigned wireless adapter driver when a laptop hard drive fried, and even though I created the “rescue” disks before the drive went out, I could not get the wireless driver to install once windows was loaded.   Toshiba did not have signed drivers even on their website for the laptop.  I tried a  few things to disable the signed requirement, but ended up messing up the system.

    It turns out in my case that Toshiba has sent “signed” drivers to Microsoft Update.   I purchased another windows 7 license and loaded the laptop from scratch.  The drivers on the Microsoft disk loaded the driver for the network connection, and then it went to Microsoft Update online and successfully loaded a driver for the wireless card.

  • blop

     hum… so you writed that answer with what? Telepathy with the computer?

  • Sfdsf

    fuck you

  • Simsterman

     if you use the deletevalue loadoptions you remove all loadoptions and this will in most cases cause system problems !!!!

    run cmd as administrator
    use bcdedit.exe -set loadoptions EENABLE_INTEGRITY_CHECKS
    bcdedit.exe -set loadoptions TESTSIGNING OFF

  • awapaho

    maybe he has 2 computers

  • Garthh

     Same here, i have win7 ultimate…this should be easy enough through group policy editor…also having problems with compatibility mode. I reset my permissions to “god mode” still no options.
    Would really like to hear from a certified winddows Guru on this matter.


  • LarMo

    according to http://support.microsoft.com/kb/2509241, to fix the TEST MODE issue:

    bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
    bcdedit.exe -set TESTSIGNING OFF
