Ghot, I know my way around Spec. Since you're sporting I'll give it a shot. Standby.
I just went back and looked at your first post. I don't have a guide for Intel Iris X graphics. Just for AMD and Nvidia.
The reason to use DDU is that it's quite common to just do something simple like a grfx driver update, and end up with driver corruption. This is what prompted Wagnard to develop DDU.
It "completely" removes the old driver and all it's pieces.
Then when we install the new driver, we get no corruption.
Lately with Microsoft trying to install "their" grfx drivers, it's even worse.
So generally...
Download the latest driver for your grfx part. Download DDU.
Unhook the internet to stop MS from intruding.
Reboot into Safe Mode and run DDU.
Reboot back into normal mode and install your grfx driver.
Rehook the internet.
Here's a pic showing what it looks like for Nvidia...
I'm posting this pic cause I don't know what you will see at the top-ish
right...
You have to choose the stuff at the top-ish
right.
After running DDU, all that will be left is the basic Microsoft driver, that came with Windows 11.
P.S. I wasn't trying to intimate that you didn't know your specs.
P.P.S. DDU guide:
