Update all PowerShell Modules with one Script

Recently I had the Idea for a PowerShell script to report the local and online Versions of all installed Modules. quickly I adopted the Screipt to do the Update as well. I am using that for my regular System Checks.

So here is my Script.


Besides my standard Logging Function, you have multiple Variables to configure. -> Post

$Module: Here, you can run the Script for a specific Module or for All Module installed
$AutoUpdateLevel: Here, you can control which Majority is updated immediately.

# v1.0 (24.05.2022) - Init Release

#region Parameters
[string]$LogPath = "C:\Users\seimi\OneDrive - Seidl Michael\2-au2mator\1 - TECHGUY\GitHub\PowerShell-Tools" #Path to store the Lofgile, only local or Hybrid
[string]$LogfileName = "UpdatePSModule" #FileName of the Logfile, only local or Hybrid
[int]$DeleteAfterDays = 10 #Time Period in Days when older Files will be deleted, only local or Hybrid

$Module = "ALL" #Module Name or ALL
$AutoUpdateLevel = "Minor" #Patch, Minor, Major

#endregion Parameters

#region Function
function Write-TechguyLog {
        [ValidateSet('DEBUG', 'INFO', 'WARNING', 'ERROR')]

    #Decide Platform
    $environment = "local"
    if ($env:AZUREPS_HOST_ENVIRONMENT) { $environment = "AAnoHybrid" }
    if ($env:AUTOMATION_WORKER_CERTIFICATE) { $environment = "AAHybrid" }
    if ($environment -eq "AAHybrid" -or $environment -eq "local") {
        # Set logging path
        if (!(Test-Path -Path $logPath)) {
            try {
                $null = New-Item -Path $logPath -ItemType Directory
                Write-Verbose ("Path: ""{0}"" was created." -f $logPath)
            catch {
