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.
