WinPE 3.0 and Powershell

[monarch684]

I have create a PowerShell script that builds my WInPE 3.0 and then writes it to my choosen jump drive. I automate some changes in the WinPE that seem to crash WinPE when launched. On the other hand if I make the same changes manually everything works fine. The actual WinPE build is fine it is the startnet.cmd that I am editing. Here is the code:

$dir = "C:\WinPE64"
$waik = "C:\Program Files\Windows AIK\Tools\amd64"
$tools = "C:\Program Files\Windows AIK\Tools\PETools\amd64"
$pak = "C:\Program Files\Windows AIK\Tools\PETools\amd64\WinPE_FPs"
$cmd = "$dir\mount\Windows\System32\startnet.cmd"

CLS;

As you can see here:

Write-Host "Adding GUI Interface to WinPE" -foregroundcolor magenta
<#$startnet = [diagnostics.process]::start("notepad.exe", "'$dir\mount\Windows\System32\startnet.cmd'") 
$startnet.waitforexit() #>

Write-Output "echo Initialized!" >> $cmd
Write-Output "echo Connecting to Image Server ..." >> $cmd
Write-Output "net use Z: `"\\SRHS-SUP-FS\Desktop Support\Images`"" >> $cmd
Write-Output "echo Connected!" >> $cmd
Write-Output "cd /d Z:\" >> $cmd
Write-Output "echo Launching GUI Interface ..." >> $cmd
Write-Output "index.hta" >> $cmd
Write-Host ""

I have palyed with manually entering the code and automating the input of the code. The error I get when I automate this is:

X:\ windows\system32> @

' @' is not recognized as an internal or eternal command, operable program or batch file.

Any ideas why this works when I manually edit this file verses automatically editting this file?

It doesn't like the default unicode encoding of out-file. It also appears to have a problem with the file being "open" at the same time you are writing to it, though since the default startnet.cmd file only has the one wpeinit line it may not make a difference to you.

Personally I would replace this:

Get-Content $cmd | Where {$_ -ne "wpeinit"} | Out-File $cmd
Write-Output "@echo off" >> $cmd
Write-Output "echo Inititalizing WinPE ..." >> $cmd
Write-Output "wpeinit" >> $cmd
Write-Output "echo Initialized!" >> $cmd
Write-Output "echo Connecting to Image Server ..." >> $cmd
Write-Output "net use Z: `"\\SRHS-SUP-FS\Desktop Support\Images`"" >> $cmd
Write-Output "echo Connected!" >> $cmd
Write-Output "cd /d Z:\" >> $cmd
Write-Output "echo Launching GUI Interface ..." >> $cmd
Write-Output "index.hta" >> $cmd

With something like this:

$startnet = Get-Content $cmd | Where {$_ -ne "wpeinit"}
$startnet +=  "@echo off" 
$startnet +=  "echo Inititalizing WinPE ..." 
$startnet +=  "wpeinit" 
$startnet +=  "echo Initialized!" 
$startnet +=  "echo Connecting to Image Server ..." 
$startnet +=  "net use Z: `"\\SRHS-SUP-FS\Desktop Support\Images`"" 
$startnet +=  "echo Connected!" 
$startnet +=  "cd /d Z:\" 
$startnet +=  "echo Launching GUI Interface ..." 
$startnet +=  "index.hta" 
Out-File -filepath $cmd -InputObject $startnet -Encoding ASCII

I tried this:

$startnet = Get-Content $cmd | Where {$_ -ne "wpeinit"} 
$startnet +=  "@echo off"  
$startnet +=  "echo Inititalizing WinPE ..."  
$startnet +=  "wpeinit"  
$startnet +=  "echo Initialized!"  
$startnet +=  "echo Connecting to Image Server ..."  
$startnet +=  "net use Z: `"\\SRHS-SUP-FS\Desktop Support\Images`""  
$startnet +=  "echo Connected!"  
$startnet +=  "cd /d Z:\"  
$startnet +=  "echo Launching GUI Interface ..."  
$startnet +=  "index.hta"  
Out-File -filepath $cmd -InputObject $startnet -Encoding ASCII

and got this:

echo off echo Initializing WinPE ... wpeinit echo Initializied! echo Connecting to Image Server ... net use Z: “\\SRHS-SUP-FS\Desktop Support\Images” echo Connected cd /d Z:\ echo Launching GUI Interface ... index.hta

X:\windows\system32>

It looks like there are no hard returns being put in.

[monarch684]

I modified the script as follows:

$startnet = Get-Content $cmd | Where {$_ -ne "wpeinit"} 
$startnet +=  "@echo off`r`n"  
$startnet +=  "echo Inititalizing WinPE ...`r`n"  
$startnet +=  "wpeinit`r`n"  
$startnet +=  "echo Initialized!`r`n"  
$startnet +=  "echo Connecting to Image Server ...`r`n"  
$startnet +=  "net use Z: `"\\SRHS-SUP-FS\Desktop Support\Images`"`r`n"  
$startnet +=  "echo Connected!`r`n"  
$startnet +=  "cd /d Z:\`r`n"  
$startnet +=  "echo Launching GUI Interface ...`r`n"  
$startnet +=  "index.hta`r`n" 

It now works. Here is the final script:

$dir = "C:\WinPE64"
$waik = "C:\Program Files\Windows AIK\Tools\amd64"
$tools = "C:\Program Files\Windows AIK\Tools\PETools\amd64"
$pak = "C:\Program Files\Windows AIK\Tools\PETools\amd64\WinPE_FPs"
$cmd = "$dir\mount\Windows\System32\startnet.cmd"

Strange. It added all of the carriage returns when I tested it before posting otherwise I would have added them.
