Hello RBM,

So... The way the Intel graphics driver package works is that it checks if you have a vanilla computer or a special one. That's why you can almost never install these on the Dell computers as unless Dell has said Yes, then the installer simply refuses claiming incompatibility. That's why Intel did their webpage doing the manual change.

When you reboot, Windows will either fetch the driver from the driver store, or from Windows Update (WU). You can't forbid the installation of device drivers from WU in a standard Windows 10 installation.

The last 4 digits are the version of the driver. The first ones are about the capability of the driver (which WDDM, DirectX, branch). So, if your first one is 21 it means it supports WDDM 2.1... It means, only compare the last 4 numbers to check what is installed. Alternatively, if you look at or post the system_details.txt from our logs, it will state the version in use.

I would recommend disabling the advanced DisplayLink logging. It captures much more stuff, and doesn't do a rolling log files. It's nice when the issue can take a while to appear but the increased number of hard drive access has an effect on performance, and on the footprint of these logs... This is only useful in very particular conditions like debugging. We use the same tool (with more options) internally with machines running tests all year round so having the verbose option can be interesting when there is no error.

Can you check if you've got any WudfHost_*.dmp with a timestamp matching the time of the observed crash? They may be in C:\CrashDumps, or C:\Windows\Minidump.
They compress very well.

Then, you can do the logs reset in the tool, it will free your drive.
