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

    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!!!

    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.

    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, to fix the TEST MODE issue:

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