I set up a new laptop on (18/02/2023) Windows 10 Pro Build 19045.2728
8 Quality updates installed at the time.
Checked the laptop today before deployment.
Unable to open display settings.
Error: ms-settings:display
This file does not have an appp associated with itfor performing this action.Please install anapp or, if one is already installed , create an association in theDefault Apps Settingspage.
As it is a new system I took the risk and installed the deferred KB5023773 (Without the optional quality update) which fixed the issue.
Maybe this will help someone …
