Disable driver digital signature enforcement Windows 8.1

[Bostonjunk]

Hi,

I wonrk for a company supplying ePOS equipment - when a till goes wrong we can set up people's perosnal laptops to function as a temporary ePOS machine until a replacement arrives.

This requires installation of thermal receipt printer drivers - unfortunately the manufacturer has not got them digitaly signed.

One of our clients had an HP Windows 8.1 laptop (model unknown but that's not important), upon trying to follow procedures to disable digital signature enforcement ( which normally goes - Advanced Startup > Troubleshoot > Advanced Options > Statup Settings) the normal troubleshoot menu has been replaced by some HP recovery thing - this has removed the necessary functions.

Is there any way around this? I cannot find any info on the HP site even acknowledging this. I've spent nearly two hours on the phone unsucessfully trying to get this working when it should be a pretty quick and straightforward procedure.

I'm quite annoyed.

What gives, HP??

Hi,

Here's an alternative method.

Open an elevated command prompt and enter the following.

bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit -set TESTSIGNING ON

Restart the notebook.

To re-enable, just enter the above commands again, substituting ENABLE instead of DISABLE and OFF instead of ON

Awesome advice - exactly what I needed. Thank you!

This is actually better than the standard procedure and no guides online anywhere mention this!

Kudos to you!

Hi

The DISABLE_INTEGRITY_CHECKS command successfully applies. When command bcdedit -set TESTSIGNING ON, I get this: "An error has occured setting the element data. Value is protected by Secure Boot protocol; it can not be changed nor erased"

I'm using windows 8.1 x64 on Asus N56Vz

What gives?

Hi, 

I am using HP 250, I am trying to disable driver digital signature in windows 8.1

The DISABLE_INTEGRITY_CHECKS command successfully applies.

However, when command bcdedit -set TESTSIGNING ON, I get this: "An error has occured setting the element data. Value is protected by Secure Boot protocol; it can not be changed nor erased"

May I know is there any other option I can do in order to disable driver digital signature?

It seems that the Alien Blob that runs microsoft from deep beneath the earth has decided that this fix no longer works with windows 8.1.

We need our computers to talk to hardware. This registration mechanism is a clear example of a software company tanlged up in it's own self importance, merrily skipping off into the tangled undergrowth, as all its' customers abandon it. A company that will quickly fade in to oblivion and irrelevance. Where will their precious global hardware registration system be then ?. In the garbage where it belongs.

Digital driver signature re-inforcement ??!

Remind me to use this next time I am installing a control system for a nuclear reactor.

In the mean time, I want to print out a girrafe on a 3D printer, so the best solution is just download and install free linux, and cast windows 8.1 out the window(s).
