Digitally signed drivers are mandatory for kernel-mode drivers in 64-bit versions of Windows.

Hi,

It's probably an incompatible driver; the core isolation and protection kernel must be blocking that driver.

If possible, take a screenshot of the blocking error screen and post it here.

Thanks

Hi,

I understand, but I wanted to see which driver is causing the problem, hence the request for a screenshot. Perhaps disabling core isolation and kernel DMA protection in Windows Security can solve it, but first we can try reinstalling the driver and see if that fixes it.

sorry, I am try to get screen shot, but it does not allow me to insert it. I am already disable core isolation and that kernel dma protection in the core isolation is always disable. it just when i try to run this driver, the window driver policy is blocked.

Hi,

In the case of WHP, the other option is to disable secure boot according to the information to try to start it and avoid the freeze. If possible, post a screenshot on OneDrive or Google Drive and post the link here.

Thanks

Hi,

That's because you have Smart App Control enabled. In that case, you would have to disable this option. However, there's a catch: you can only reactivate this option by reinstalling Windows. If this app is important, you can disable it.

Here's an explanation of what Smart App Control is: https://support.microsoft.com/en-us/windows/smart-app-control-frequently-asked-questions-285ea03d-fa88-4d56-882e-6698afdb7003

Let me know what you decided.

Thanks
