UAC is disabled (EnableLua reg key = 0) on our Windows 7 build and neither standard users nor admins see any UAC prompts. We want to replicate this on our Windows 8.1 build without breaking the Microsoft Store, but disabling UAC by setting the EnableLua reg key to 0 breaks the Microsoft Store, so we have to set the EnableLua reg key to 1 which means standard users are prompted for credentials when trying to access regedit, etc. Not ideal. In an attempt to suppress the UAC prompts for standard users, I changed the ConsentPromptBehaviorUser reg key from 0 to 6, based on the following testing:-

0 = "your system administrator has blocked this program" when trying to run ActiveSetup reg keys during 
1 = asks for admin credentials when launching UAC which is set to Always Notify
2 = asks for admin credentials when launching UAC which is set to Always Notify
3 = asks for admin credentials when launching UAC which is set to Always Notify me (and do not dim my desktop) when:
6 = asks for admin credentials when launching UAC which is set to Never Notify

How can we suppress all UAC prompts for standard users (i.e. non-admins) without breaking the Microsoft Store please?

Thanks

It is our company policy to distinguish standard users from admins by not adding standard users to the Administrators group so that standard users cannot install apps or perform any other admin-only tasks. It is also our company policy to suppress all UAC prompts for admins and standard users. This combination works perfectly on our Windows 7 build.

So why does this appear not possible on Windows 8 without breaking the Microsoft Store please? There must be a way to not break the Microsoft Store (EnableLUA must = 1) and suppress all UAC prompts (ConsentPromptBehaviorUser = ?)?
