Parallels 12.1.1, Windows 10, with updates up to date. The driver consistently fails to load when (re)installing Parallels Tools, and subsequently upon reboot. This results in resolution not being properly adjusted, and all other unpleasantries associated with MS video driver fallback. This used to work, so an update (either Parallels, or Windows, or both) broke this. Tried reinstalling both Parallels and Parallels tools with no effect.
