Microsoft's roll out of the October 2018 Update (Redstone 5) for Windows 10 has not exactly been smooth. From audio woes to missing files, it appears the latest upgrade to Windows 10 needed a bit more time in the oven before serving up. That said, Microsoft has been busy fixing various bugs with the October 2018 Update, including one that was causing some HP systems to experience the dreaded blue screen of death (BSOD).
"In working with HP, Microsoft has identified an HP driver with known incompatibility with certain HP devices on Windows 10 versions 1803 and 1809. On October 11, 2018 Microsoft removed the driver from Windows Update to reduce the number of devices affected. Additionally, Microsoft has released this update to remove the incompatible driver from devices pending reboot. HP is actively working on this issue," Microsoft said.
The cause of headaches for some HP device owners is a keyboard driver. According to ZDNet, which has been following the issue, some users traced the issue to an incompatibility with HP's 'HpqKbFiltr.sys' driver and Microsoft's KB4464330 (for version 1809) and KB4462919 (for version 1803) updates.
Microsoft's solution is the remove the driver altogether, just as some users had already been doing to get rid of the BSOD error. It's still an option to remove the driver manually, or affected users can ping Windows Update, which will essentially do the same thing on affected systems. It's really more of a stopgap solution until HP issue a driver update that plays nice with the two most recent versions of Windows.
