List All Packages From a Task Sequence

Here is a short PowerShell script to list all packages that a ConfigMgr Task Sequence is using, and export to a text file.

# Global Settings
$SiteCode = "PS1" 
$ProviderMachineName = "cm01.corp.viamonstra.com" 
$TaskSequenceName = "Windows 10 Enterprise x64 21H2 MDM BranchCache XL"

 # Import the ConfigurationManager.psd1 module 
if((Get-Module ConfigurationManager) -eq $null) {
    Import-Module "$($ENV:SMS_ADMIN_UI_PATH)\..\ConfigurationManager.psd1"
}

# Connect to the site's drive if it is not already present
if((Get-PSDrive -Name $SiteCode -PSProvider CMSite -ErrorAction SilentlyContinue) -eq $null) {
    New-PSDrive -Name $SiteCode -PSProvider CMSite -Root $ProviderMachineName 
}

# Set the current location to be the site code.
Set-Location "$($SiteCode):\" 

# Disable -Fast check warnings
$CMPSSuppressFastNotUsedCheck = $true

# Get Task Sequence (Do not use -Fast switch, won't return packages if you do)
$TaskSequence = Get-CMTaskSequence -Name $TaskSequenceName

# Get all unique reference packages
$TaskSequencePackages = $TaskSequence.References | select Package -Unique

# Export to a text file without header information
$TaskSequencePackages | ConvertTo-Csv -NoTypeInformation | Select-Object -Skip 1 | Out-File "E:\Setup\TaskSequencePackages.txt"
