Hello, I tried installing Windows Server 2019 and 2022 on my laptop but both have the same problem, the touchpad is not working. After a lot of different things tried, I am almost sure the problem is the lack of a correct hidi2c.sys driver, as in normal Windows I have a driver called "I2C HID Device", which uses the hidi2c.sys and mshidkmdf.sys. On a normal Windows installation, Windows automatically installs this hidi2c.sys and then 3 other devices show up. "Microsoft Input Configuration Device", "ELAN HID Class Filter Device" and "ELAN PrecisionTouchpad Filter Driver". If I uninstall the hidi2c.sys on normal Windows, then the other 3 devices are gone, just like on Windows Server, until I reinstall it. Windows Server has the mshidkmdf.sys, but not the hidi2c.sys. I have another laptop which uses an ELAN Touchpad, but it's not connected via AMD I2C, so I am guessing that's why it works. I only found a thread which documents this problem a bit, on eevblog (www dot eevblog dot com/forum/general-computing/windows-server-default-driver-broken/). All other devices work fine, like GPU and Wi-Fi. The OS is installed as secondary OS on my laptop, so I can try suggestions. Thanks.
server editions don't have the same driver data base as windows 10 it lots more restrictive you have to manually find & install the drives windows 10 drivers work but you have to install them
Do you have an unknown device on server device management? If yes you could try to point it to the windows folder of a windows 10 installation on the same machine.
my touchpad doesnt work with servers editions so i changed to unsigned driver enforcement changed the ini to like amd64.10 remove the cat file and manually installed it
Yes, there's an unknown device, I tried dumping the driver from a few windows versions, including the server's PE Environment (which has touchpad support for some reason), but it says no compatible devices found. I think i can get it to work, by modifying the .inf, but I am not sure how.
Nevermind, it worked with driver signature disabled, omg, thank you so much, now I can use it on my laptop. LTSC 2019 is bad on ryzen so there wasnt really a good OS for it.
