PCI Encryption/Decryption Controller for HP 15-126ds laptop

[JR4RU]

Had to reinstall Windows 7 to this laptop. Was able to find all device drivers except for 2.

PCI Encryption/Decryption Controller

and

Unknown Device

In the properties under Details tab, Hardware ID Value is ACPI\MSFT0101

Help is appreciated!

Hi:

You need this driver for the PCI E/D Controller...

This package provides the Intel Trusted Execution Engine Interface (TXE) Driver for the supported notebook models running a supported operating system. The Intel Trusted Execution Engine Interface enables the Secure Boot and provides services required for platform security features such as Intel Platform Trust Technology (Intel PPT).

File name: sp72085.exe

And you need to install the hotfix for the unknown device (which is the TPM 2.0 module), from the link below.

Thanks for the quick reply!

The driver for the PCI E\D Controller worked perfetly!

I downloaded the Hotfix from MS, and when i run it my computer  startts the Windows Update Standalone Installer, the "Searching for updates on this computer..." starts to run, and runs on and on, after an hour i finally had to cancel it, i had to believe something was wrong.

I suppose that this feature does not work in Windows 7 from what I have ready anyway, all the Hotfix was going to do is remove the yellow triangle from the unknown device.

Since i do not think i need TPM on this PC, maybe i could just Disable the unknown device.

Any advice?

Thanks again!

You're very welcome.

Yes, you are correct in that the TPM has no value unless you are running the Ultimate or Enterprise Version of W7.

I am surprised the hotfix didn't work though.

A long time ago before MS released the hotfix, I found this basic driver which I have zipped up and attached below.

You can see if this works instead...to install, download and unzip the file to its folder.

Do not do anything with the files in the folder.

Go to the device manager and click on the unknown device needing the driver.

Click on the driver tab.  Click on Update Driver.  Select the Browse my computer for driver software option and browse to the driver folder you unzipped.

Make sure the Include subfolders box is checked and see if the driver installs that way.

Your zipped driver worked!

Have a great day!
