            If $ioSwitch = 0 Then
                Return SetError(1); Error reg and switch are equal - off
            EndIf
        ElseIf RegRead($strReg, $strKey) = 1 Then
            If $ioSwitch = 1 Then
                Return SetError(2); Error reg and switch are equal - on
            EndIf
        Else
            RegWrite($strReg, $strKey, "REG_DWORD", $ioSwitch)
            Return 1; Good return
        EndIf
    Else
        Return SetError(3); Not Vista
    EndIf
EndFunc ;==>_Reg_UAC

Pretty bad but can be useful. I don't use SetError() much so it's probably wrong

Thank you it works good

What's wrong with System Configuration Utility (msconfig.exe)? I see no reason for the frequent use of activate/deactivate UAC. Moreover it will work only after reboot your system.

I think the only think wrong with it that I can see is that it returns 0 and ets Error to 1/2 when It's not changing the value.

I would change it to this...

If $ioSwitch = 1 Then
    Return SetError(2, 0, 1); Error reg and switch are equal - on
EndIf

or maybe:

If $ioSwitch = 1 Then
    Return SetError(0, 2, 1); Error reg and switch are equal - on
EndIf

as then It won't set off alarm bells when the values are equal.

Don't know if thats what you wan't, but it makes sense as if you tell it to set the key to 2, even if it doesn't do anything, if the key ends up 2 then it should be OK.

Other than that, I think this should be run by anyone on vista... saves everyone some trouble.

I don't get it. How?

[James]

Old topic, but still worth noting. Apparently, this does not work on Windows 7, a different key? I haven't tested it, but thought it would be useful to note

Hello

How can check, if UAC is Active ?

like require the state of UAC. maybe can check, running service, registry, or dll call.

Yashied you are right.

the regkey: $strReg = "HKLM64\Software\Microsoft\Windows\CurrentVersion\Policies\System"

the settings are activ after reebot.

If I remember correctly, there is a key (I think GeoSoft noted this), that doesn't require a reboot.

That should not require a reboot on Windows Vista.
