MS sample drivers don't install
My PC is a i5 x64, Windows 10 device. I tried to install the passthrough sample of the WDK driver samples collection 2022. I installed VS 2022, SDK and WDK only recently. I opened the passthrough.sln file and the settings in properties were as follows:
x64, Debug, KMDMWindows10, Driver; Build only, (no external target PC)
After commenting out the lines which produced many errors in wdm.h, ntifs.h, and ntddk.h and after editing the .inf file (ntamd64 decorations) I eventually got a passthrough.sys and even a passthrough.cat file.
I tried to install this driver package using the Device Manager. (I have installed my own unsigned drivers by the same method many times in the past and, until recently, that always worked fine, the drivers were installed and also worked.)
This time I got an unexpected error while installing the passthrough.inf: The folder you specified doesn't contain a compatible software driver for your device. ... Make sure it works with x64-based systems.
After verifying and correcting my own .inf file by infverif.exe (INF IS VALID) it threw exactly the same error message. I have absolutely no clue why.
pnputil installs both drivers (added driver packages: 1), but I havn't found them in the Device Manager. pnputil /enum-devices also doesn't show them. They don't work either.
I am at my wits end. Is it a wrong error message? Can anyone help me?
