Self building powershell script

I'm currently trying to make ps1 script that creates another ps1 script via echo, add-content, clip and so forth.

What I'm trying to do is write a ps1 script that gets a folder, stores it in a variable ($VBS) and writes the new ps1 to a file in that folder to afterwards run it from that folder. Here's my code so far:

if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe -windowstyle hidden "-NoProfile -ExecutionPolicy RemoteSigned -File `"$PSCommandPath`"" -Verb RunAs; exit }
cd \ 
$VBS = gci -Recurse -Filter "Folder" -Directory -ErrorAction SilentlyContinue -path "C:\"
cd "$env:USERPROFILE\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"
echo $VBS | ForEach-Object { $_.FullName } > KickStart.ps1
cat KickStart.ps1 | set-clipboard   
echo '"if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe -windowstyle hidden "-NoProfile -ExecutionPolicy RemoteSigned -File `"$PSCommandPath`"" -Verb RunAs; exit }' > KickStart.ps1
add-content KickStart.ps1 "`ncd \"
add-content KickStart.ps1 "`ncd"
add-content KickStart.ps1 ' "'
add-content KickStart.ps1 | get-clipboard
add-content KickStart.ps1 '"'
add-content KickStart.ps1 '`nstart File.vbs' 
add-content KickStart.ps1 '`n cd \'
add-content KickStart.ps1 '`ncd "$env:USERPROFILE\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"'
add-content KickStart.ps1 'rm KickStart.ps1'

The final product (KickStart.ps1) should look like this:

if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe -windowstyle hidden "-NoProfile -ExecutionPolicy RemoteSigned -File `"$PSCommandPath`"" -Verb RunAs; exit }
cd \
cd "C:\PATH\TO\FOLDER"
start file.vbs
cd \
cd "$env:USERPROFILE\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"
rm KickStart.ps1

Instead my current scripts generates this:

"if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) { Start-Process powershell.exe -windowstyle hidden "-NoProfile -ExecutionPolicy RemoteSigned -File `"$PSCommandPath`"" -Verb RunAs; exit }

cd \

cd
 "
"
`nstart File.vbs
`n cd \
`ncd "$env:USERPROFILE\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"
rm KickStart.ps1

I seriously don't know what I'm doing wrong, I've put in almost 12 hours finding the solutions, help would be appreciated.

Although not entirely sure what you are trying to achieve, but looking at the desired output, why not build the content using a Here-String like this:

@'
if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]"Administrator")) { 
    Start-Process powershell.exe -WindowStyle Hidden -NoProfile -ExecutionPolicy RemoteSigned -File "$PSCommandPath" -Verb RunAs
    exit 
}
Set-Location \ 
Set-Location "C:\PATH\TO\FOLDER"
Start-Process file.vbs
Set-Location \
Set-Location "$env:USERPROFILE\AppData\Roaming\Microsoft\Windows\Start-Process Menu\Programs\Startup"
Remove-Item KickStart.ps1
'@ | Set-Content -Path 'THE PATH FOR THE KickStart.ps1 FILE'

Result:

if (!([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]"Administrator")) { 
    Start-Process powershell.exe -WindowStyle Hidden -NoProfile -ExecutionPolicy RemoteSigned -File "$PSCommandPath" -Verb RunAs
    exit 
}
Set-Location \ 
Set-Location "C:\PATH\TO\FOLDER"
Start-Process file.vbs
Set-Location \
Set-Location "$env:USERPROFILE\AppData\Roaming\Microsoft\Windows\Start-Process Menu\Programs\Startup"
Remove-Item KickStart.ps1
