Permanent disable Driver signature verification

Question

Hello.

I have Win 10 Home 64 bit.

I use a third party USB connected Fax. Its driver has no Microsoft signature. I want to disable the Microsoft enforce driver signature verification permanently because the Fax is working in this mode only.

I did the following action:

1. CMD (as admin) ->bcdedit.exe /set nointegritychecks on

It doesn't work.

I don't have the GP therefore I can't disable this Policy.

I found some solution by using The Registry but I don't know how to implement it and I'm afraid to spoil the OS.

Please help to resolve the problem.

Best regards.

Marina

Hi marinamarina4,

You can give the following commands in Command Prompt (Admin) a try:

bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit.exe -set TESTSIGNING ON

After doing so, restart your PC.

If it still doesn't work, change the startup settings.

1. Start your computer and then keep pressing the F8 key before Windows starts. You will see the Advanced Options screen.
2. Choose Troubleshoot > Advanced options > Startup Settings and click the Restart button.
3. When your computer restarts you’ll see a list of options. Press F7 on your keyboard to select Disable driver signature enforcement.
4. Your computer will now restart and you’ll be able to install unsigned drivers.

However, if you wish to modify the registry, please note that serious problems might occur if you modify it incorrectly. Therefore, make sure that you follow the steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if problem occurs. For more information about how to back up and restore the registry, you may refer to this Microsoft article.

Let me know if you need further assistance.

Answer 2

Hello. Thank you for your prompt reply. The first option didn't work. The second option works until the first restart. How can I disable the signature enforcement permanently?
