I usually search for the iGPU device ID, which is available on Intel ARK, then go to the list of Intel iGPUs on the english version of Wikipedia, as the list is very detailed and iGPUs with identical names can be distinguished by the device ID you got from Intel ARK. TechPowerUp has a nice GPU specs database too, but navigating through it can be a bit challenging…
This has been happening for ages and while I blamed Windows initially, I highly suspect it’s an Intel issue as it doesn’t happen with NVIDIA (neither with AMD) dedicated GPUs.
I’ve gone down that rabbit hole a few times and I’m aware of two methods to avoid that. The first is to let Windows Update install the old OEM driver, then you install the new one on top without removing the previous driver (e.g. do not check the “perform clean install” button on Intel installer, nor use DDU).
The second method is using DDU to remove all precious drivers, then install the most recent one from Intel without internet (to prevent Windows Update to auto download the OEM driver before you can act), and, after that, restore your connection and quickly run wushowhide.diagcab (can’t link it right now but it’s easy to find, just Google it) to hide the OEM driver before Windows Update downloads/installs it. Beware that feature updates normally reset the list of hidden updates, so you’ll need to do that again whenever a big update (like 23H2) drops…
Intel Unison does not work on Windows 10. Downloading the app bundle externally and/or editing the app manifest to remove the OS version check won’t magically make it work on Windows 10, current version requires Windows 11…
