You dont need to use VBScript for that

just type one command in the command line


 Disable UAC
 C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f
 
 Enable UAC
 C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 1 /f

or make batch, the run it from command line with argument (1 enable UAC, 0 Disable)
Example UAS.bat 1 or UAC.bat 0:

@echo off
 
C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d %1 /f

Here you go:
Const UAC_ENABLE = 1
Const UAC_DISABLE = 0
Const UAC_REGKEY = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA"
 
If Wscript.Arguments.Count <> 1 Then
    Wscript.Echo "Usage: " & Wscript.ScriptName & " Enable|Disable|Status"
    Wscript.Quit
End If
 
Set Shell = CreateObject( "WScript.Shell" )
 
If UCase(Wscript.Arguments.Item(0)) = "ENABLE" Then
    Shell.RegWrite UAC_REGKEY, UAC_ENABLE, "REG_DWORD"
    Wscript.Echo "UAC Enabled, please reboot..."
    Wscript.Quit
End If
 
If UCase(Wscript.Arguments.Item(0)) = "DISABLE" Then
    Shell.RegWrite UAC_REGKEY, UAC_DISABLE, "REG_DWORD"
    Wscript.Echo "UAC Disabled, please reboot..."
    Wscript.Quit
End If
 
If UCase(Wscript.Arguments.Item(0)) = "STATUS" Then
    If Shell.RegRead(UAC_REGKEY) = 0 Then
        Wscript.Echo "UAC is Disabled."
    Else
        Wscript.Echo "UAC is Enabled."
    End If
        Wscript.Quit
End If

i tested the code whenever i ran it , just a message display "Enable/Disable/Status" nothing else.

do you want me to create a dword with name enable LUA and assign it value 0 for disable and 1 for enable UAC.

otherwise please explain the above code

The above script must be run form command line:

For example to disable UAC run form command line: "cscript UAC.vbs disable"
The UAC.vbs may be different in your case, depending of the name you gave to the script"

If you want just to disable UAC use this code:
Const UAC_DISABLE = 0
Const UAC_REGKEY = "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA"
 
Set Shell = CreateObject( "WScript.Shell" )
Shell.RegWrite UAC_REGKEY, UAC_DISABLE, "REG_DWORD"
Wscript.Echo "UAC Disabled, please reboot..."

Yes the last snippet will disable the UAC.
You will have to restart the computer after you run the script for changes to take effect.

You have to run this script as administrator, only with administrative permissions you can disable/enable UAC for all users
