Windows 10 1903 – BSOD (WDF_VIOLATION)

After updating an iMac Late 2010 to Windows 10 1903 I got a blue screen “WDF_VIOLATION”. After checking the minidump, I could see that the MacHALDriver.sys (Macintosh Hardware Application Layer Driver) is involved. After renaming the file (c:\windows\system32\drivers\MacHALDriver.sys) over the network (works because the system crashes after user login) or in safe mode and rebooting, I was able to log back in. Since I don’t use an Apple keyboard I can do without the driver.

While researching I found out that other users also have problems with a similar keyboard driver for HP. In this case it is called HpqKbFiltr.sys. Is also responsible for the hotkeys (screen brightness and co.).
