Hi,

For correction, Dell itself has created a utility to remove the driver and replace it with version 2.6.

The link is from the Dell manufacturer of your laptop or desktop.

Hi,

In this case, it would be in the taskbar if you're on Windows 11. Click the magnifying glass icon and type: msinfo32.exe and click OK.

Hi,

Please update your BIOS to the latest recommended version.

If you have Dell Applications installed, please uninstall Dell Update or Dell Command Center.

Before updating the BIOS, you must close all programs and download and run the update from the link below:

https://dl.dell.com/FOLDER05066009M/1/O9010A30.exe

Wait for the process to finish. Do not stop the process under any circumstances. Wait for it to finish; if you stop the BIOS update process, your PC may stop working.

After the BIOS update process, you will need to run the repair using the link below:

https://dl.dell.com/FOLDER07338430M/3/Dell-Security-Advisory-Update-DSA-2021-088_DF8CW_WIN_2.1.0_A02_02.EXE

The link is from the Dell manufacturer of your laptop or desktop.

Hi,

So you need to update the BIOS. The links are working; you'll download the BIOS first and update it, then use the post-processing tool.

Is it giving any errors?

Hi,

Sorry, I'll explain:

First, you need to update the BIOS to the latest version. First, download the file from the link below:

https://dl.dell.com/FOLDER05066009M/1/O9010A30.exe

After downloading, close all programs and run the file as administrator > press continue or run and wait for the process to load and update. You don't need to touch anything, just wait, it will complete the process automatically.

Second, after restarting and starting Windows, download the file from the link below and run it as administrator:

https://dl.dell.com/FOLDER07338430M/3/Dell-Security-Advisory-Update-DSA-2021-088_DF8CW_WIN_2.1.0_A02_02.EXE

Click run or continue and wait for it to complete the process.

This will fix the problem.

The link is from the Dell manufacturer of your laptop or desktop.

Hi,

To uninstall it, we'll remove the driver manually.

Download Autorun from the link below, extract a folder, and run Autorunx64:

https://learn.microsoft.com/pt-br/sysinternals/downloads/autoruns

After opening, go to the driver tab and find the DBUtil_2_3.Sys driver. Take a screenshot and post it here.

Hi,

Did you uninstall Dell Support Assistant?

Access the command prompt (admin) and run the command: sc.exe delete DBUtil_2_3

Hi,

Okay, now you're going to do the following: access Windows Security > Device Security > Core Isolation > disable Memory Integrity if it's already disabled. Now try updating the BIOS again and run the application I sent.

Thanks
