As Windows 7 is about to come to an end in terms of general support (such as drivers and programs,) I'm a bit forced to move to Windows 10 to even run it on newer hardware. However, I'm not at all interested in constantly having to completely update the OS every 6 months and come up with new procedures for blocking all of that obnoxious telemetry and such - hence this research. It appears that Windows 10 drivers are segregated in terms of build numbers, which means if you are running an older version of Windows 10 (such as LTSB 2015,) you cannot normally install the drivers as the .inf file will manually specify sections like "NTamd64.10.0...14393," which something like LTSB 2015 will require "NTamd64.10.0." These sections can easily be modified so that Windows 10 will let you pick up the driver and even begin the install process provided you turned off driver signing... but not always. I tried this with the HD 630 drivers by modifying both the "%Intel%" section at the top, and the "IntelGfx.NTamd64" section below it so that the .inf has "NTamd64.10.0" over the 14393 build requirement, and sure enough, LTSB will find the driver and let me start the process. However, even with this modification, I'm being hit with the dreaded "The driver selected for this device does not support this version of windows." Now, I'm trying to figure out why this happens. I followed the "iKBLD_w10_DS" to the section below and found something called "FeatureScore=D1," but LTSB 2015 and 14393 both use D1 - so that can't be the issue. And I don't see anything else in the .inf which would cause this problem either (except possibly failure to start messages from services?) Could it be that the driver itself (igdkmd64.sys) actually has a section in it which would halt the install due to an older Windows version? Could this possibly be related to the driver having a newer WDDM than LTSB 2015? To be honest, I'm not really looking forward to the future of Windows if this is indicative of future work that I have to do with it. What happened to just getting an OS and using it for 5 years or so all computers?
