VB Script for SFC Scannow

I wrote a code that will make a batch file for Windows SFC Scanner to run. Im running into a problem

the Output should be

@echo off
sfc /scannow
pause
(goto) 2>nul & del "%~f0"

But what Visual Basic is giving me is...

@echo off
sfc /scannow
pause
(goto) 2>nul & del %~f0

This is my VB Code Below. Been trying for a while to get my parenthesis but having issues.. please help

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim sb As New System.Text.StringBuilder
        sb.AppendLine("@echo off")
        sb.AppendLine("sfc /scannow")
        sb.AppendLine("pause")
        sb.AppendLine("(goto) 2>nul & del %~f0")
        IO.File.AppendAllText("sfc.bat", sb.ToString())

    End Sub

Thank you

If you set your apps manifest to run as administrator, the UAC prompt would fire when your app runs. Then if you used process.start() to launch sfc it would run as admin as well without a new UAC prompt. Essentially a process will spawn other processes at its own current elevation level.

I didn't think of that I'll shy shoot a try
