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.
Thanks.

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.

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.

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.

This guide does NOT work for my Windows7 64 bit.

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?

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.

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.

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.

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 ?

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.

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?

Does NOT work in RTM Windows 7 x64 build 7600
To disable driver signing, you have to press F8 during boot every time.
