For a guide , check : https://www.wagnardsoft.com/content/ddu-guide-tutorial

Recommended usage:

-You MUST disconnect your internet or completely block Windows Update when running DDU until you have re-installed your new drivers.
-DDU should be used when having a problem uninstalling / installing a driver or when switching GPU brand.
-DDU should not be used every time you install a new driver unless you know what you are doing.
-DDU will not work on network drive. Please install in a local drive (C:, D: or else).
-The tool can be used in Normal mode but for absolute stability when using DDU, Safemode is always the best.
-If you are using DDU in normal mode, Clean, reboot, clean again, reboot.
-Make a backup or a system restore (but it should normally be pretty safe).
-It is best to exclude the DDU folder completely from any security software to avoid issues.
Note: If you have issues for downloading the file, it could be one of your extension interfering with our hotlink protection.

Here is some applications from our partners that we recommend.
They are useful tools that may help you update / uninstall outdated drivers /programs.

I replaced v18.1.3.6 with v18.1.3.7
Changelog is the same, it's just a more robust fix.

there are few gotacha going to safe mode, the PIN does not work in the latest windows update, and it block from login, need to disable pin and use the password auth to get around it, or if you can get to the command mode you can disable the PIN by some command ( google it)

but this DDU did not work for me after repeated reboots, what worked is nvidia-erro43-fixer from egpu.io bb, it did it job very well,

Do you think you could send me the DDU logs ([email protected]) if you still have them, they are located within the DDU folder.
I never had the chance to test an eGPU so it's possible DDU miss something. I'll try to work on that.
Thank you for having shared your experience.

Edit: After some research I found out that this is not something really related to DDU.

The app you mention seems to disable some security check of the nvidia driver to allow egpu with Nvidia. Normally on some configuration NVIDIA may intentionally block the loading of the driver with a code 43 on such device.
The tool simply add a registry key to prevent that.
