Suppress all UAC prompts for standard users without breaking the Microsoft Store in Windows 8.1?

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
Scott

Hi MeipoXu, 'EnableLUA = 1' allows the Microsoft Store to work but will enable UAC and prompt users which we do not want. 'EnableLUA = 0' will disable UAC and not prompt users but it will stop the Microsoft Store working.

We want the Microsoft Store to work and to prevent users being prompted by UAC. Is this possible please?

Thanks

Hi mr5h,

The UAC is used to distinguish between the standard users and administrators.
I am a little curious. If it is acceptable to disable the UAC completely, there is no need to distinguish the standard user and administrators. In another word, we can add all the users to the administrators group.
According to my test, we could disable the UAC for administrator from the "Action center"UI with the registry key "EnableLua" value configured as "1". It is allowed to get into Windows Store with this configuration.

Hi MeipoXu, yes I have already tested these reg keys allow the Microsoft Store to work but have you tested how it affects UAC prompts for standard users? I have and I get the following error when accessing regedit:-

C:\Windows\regedit.exe
Your system administrator has blocked this program. For more information, contact your system administrator.

So, is there anyway to remove these annoying UAC prompts completely without breaking the Microsoft Store (EnableLUA = 0) please?

Thanks

Hi mr5h,

I logon as an administrator to change the registry keys. The registry keys are located in the machine catalog and all the users should be impacted.

Please logon as administrator to change the registry keys and then logon with standard user to have a check.

Best regards
