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

Hi mr5h,

The UAC is used to distinguish between the standard users and administrators.
Disabling the UAC will reduce the computer security. It is not recommended to do this.
By default, we will not be able to get windows store apps while UAC is disabled.
If we want to achieve the goal, we can give the following registry key a try.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA
Configure the value as "1" and restart the machine, you will be allowed to access the Windows Store though the UAC has been disabled.
