Powershell Start-Process pnputil.exe

Question

I'm trying to run pnputil with start-process, but it doesn't seem to work.

Here is a script that works without start-process:

$Driver = Get-ChildItem "$PSScriptRoot" -Recurse -Filter "*inf"

$InstallDriver = foreach ($item in $Driver) {
          
PNPUtil.exe /add-driver $item.FullName /install

}

But if I'm doing the same with start-process I cant get it to work :

$Driver = Get-ChildItem "$PSScriptRoot" -Recurse -Filter "*inf"

$InstallDriver = foreach ($item in $Driver) {
          
Start-Process PNPUtil.exe /add-driver $item.FullName /install

}

I have also tried

Start-Process PNPUtil -ArgumentList '/add-driver $item.FullName /install'

Start-Process PNPUtil -ArgumentList '/add-driver "$item.FullName" /install'

Start-Process PNPUtil -ArgumentList '/add-driver "${$item.FullName}" /install'

Start-Process PNPUtil -ArgumentList "/add-driver "${$item.FullName}" /install'

Start-Process PNPUtil -ArgumentList "/add-driver $item.FullName} /install"

But it doesn't work

Does anyone know why it does not work? Thanks for the help

Answer 1

They are all separate arguments. Single quotes around variables will prevent the variable from expanding plus if you enclose $variable.property in double quotes you need a subexpression $() . Instead, try this

Start-Process PNPUtil -ArgumentList "/add-driver",$item.FullName,"/install"
