Programs can't request elevation

I've been running Windows 8 x64 on an HP ENVY H8-1445 desktop for a couple of months. I have Start8 (Start button plus boot to desktop) and ModernMix (run modern apps in windows) installed to make it bearable. UAC is set at the minimum level (I build live CDs with WinBuilder and it needs to have UAC as off as it gets).

About two weeks ago, without any apparent event that triggered it, installation programs started failing. The problem was elevation; they couldn't do it. E.g. if I downloaded a file and told the browser to run it it would fail immediately. This happens in all IE, Opera, and Chrome. If I download the file and save it then run it as administrator it works fine.

There must be a setting somewhere that governs this, but I sure can't find it.

See here, maybe it will help: http://www.eightforums.com/system-security/2434-disable-uac-completely.html

I use the Rexx programming language which mostly runs via Command Prompt. Without the above change, every time I tried to run it, it would open a separate Command Prompt window then close it as soon as it finished. Made the registry change mentioned in the above link and all works well now.

Thanks ... I fond the answer on another forum as a PwerShell script (must be run elevated):

Code:
#The following is equal to the Security Policy "User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode" = "Elevate without prompting"
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows\CurrentVersion\Policies\System" -Name "ConsentPromptBehaviorAdmin" -Value "0" #Default value is 2

#The following is equal to the Security Policy "User Account Control: Allow UIAccess applications to prompt for elevation without using the secure dekstop" = "Enabled"
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows\CurrentVersion\Policies\System" -Name "EnableUIADesktopToggle" -Value "1" #Default value is 0
