Glad I didn’t install that one then.
hotfix now here
531.29 is now up on the normal update page this will replace 531.18 which hotfixed to 531.26
531.29 is the whql version
If you don’t usually I would suggest a clean install which may require a reboot, Its still good practice to switch off all secondary monitors before the upgrade starts
@Alphea thank you very much for this update.
