Stop hardcoding secrets! Now what?!
Yeah, we all know this right “STOP DOING THIS”, “STOP DOING THAT!” Yeah… that’s nice, but now what?! When you are already in the PowerShell field for some time and have created some scripts you might have been running into this topic; ‘How to deal with secrets’. There are of course solutions like KeyVault, SecureString and secret providers with API’s which help you to store the secrets you have in a secure environment. Things like this might look familiar; $password = "P@ssw0rd123!" $apiKey = "sk-1234567890abcdef" $connectionString = "Server=myserver;Database=mydb;User=admin;Password=SuperSecret123;" But what if I told you there’s a better way? A way that’s: Secure by default Cross-platform (Windows, Linux, macOS) Works with multiple backends (local, Azure Key Vault, HashiCorp Vault) Standardized across your entire team Built right into PowerShell 7+ (with some extra module support) That way forward is called ‘PowerShell SecretManagement”! What is SecretManagement? Think of PowerShell SecretManagement as the universal remote control for your secrets. With this remote control you can handle credentials for different systems while you just get one unified interface. It doesn’t matter if that secret is stored: In your local machine In an Azure KeyVault In HashiCorp Vault In KeePass, LastPass etc. The mindset remains the same ‘One remote control, to control them all’. The architecture behind it looks a bit like below; Explaination: SecretManagement “The interface where you code against” SecretStore “The default storage where your secrets live” Getting Started Let’s get started! Start PowerShell 7+ and run the code below Install-Module Microsoft.PowerShell.SecretManagement -Repository PSGallery -Force Install-Module Microsoft.PowerShell.SecretStore -Repository PSGallery -Force Now we have the required modules installed form the PowerShell Gallery it’s time to create our first vault. Register-SecretVault -name "LocalTestVault" It will ask you for the module. Enter the name “Microsoft.PowerShell.SecretStore”. (If you want you can also specify this value directly in the CMDLet by specifying the -ModuleName parameter. You should end up with something like below: First secrets Now we have the vault set-up it’s time to add some content to it. Follow the steps below to create the first secret in the vault Run the command below to create the first secret Set-Secret -Name "TestSecret" -Secret "SuperDuperSecureSecretString" If you haven’t specified the password it will now ask for one! You should end up with something like below; Cool right? On my personal blog I have the full post where I also show how to change, delete, and store complex objects.

Why does this return a .csv with the length of the group names?
Hi, I've been trying to list the names of the Entra groups a user is a member of. Most of the scripts I've found online will only display the group ID and leaves the other fields blank, if they show up at all. I found this command works in the terminal: Get-MgUserMemberOf -UserId $userPrincipalName | % {($_.AdditionalProperties).displayName} However, when I try to export it to CSV is get a single column named "Length" and a number in each row which I believe corresponds to the lenght of the group name in characters. Here's the full command: Get-MgUserMemberOf -UserId $userPrincipalName | % {($_.AdditionalProperties).displayName} | Export-Csv -Path "C:\Temp\GroupMemberships.csv" -NoTypeInformation What am I doing wrong?Problem restoring deleted user with mggraph
Hello, I have done a few 365 migration and almost everytime there are some user data that has been missed in the migration. Earlier I solved this by restoring the 365 user in the source tenant to another domain using this msol script in powershell: Restore-MsolUser -UserPrincipalName email address removed for privacy reasons -Verbose Restore-MsolUser -UserPrincipalName email address removed for privacy reasons -Verbose -AutoReconcileProxyConflicts Restore-MsolUser -UserPrincipalName email address removed for privacy reasons -Verbose -AutoReconcileProxyConflicts -NewUserPrincipalName email address removed for privacy reasons I know it is not perfect but it worked well and saved a bunch of times. I have now done another migration now and got the same issue so I need to restore the users so we can access the data again and move it. BUT! I realized today that msol service is no more, so I am kinda stuck with figuring this out in mggraph. I have tried for a few hours now and I am not sure if this even possible with mggraph. Whenever I try to build a script using Restore-MgDirectoryDeletedUser/Item which google, copilote etc tells me to use I only get this error: The term 'Restore-MgDirectoryDeletedUser/item' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. Or I get that it "works" but that the proxy/domain conflicts: Errors detected while trying to restore the user restoreUserErrors: ErrorValue:<pii><pii>E*****.E*******</pii>@domain.com</pii> ObjectType: ConflictingObjectId:, ErrorType:UserPrincipalName, ErrorId:InvalidDomainErrorValue:<pii>smtp:<pii>ee</pii>@domain.com</pii> ObjectType: ConflictingObjectId:, ErrorType:ProxyAddress, ErrorId:InvalidDomain Status: 400 (BadRequest) ErrorCode: Request_BadRequest Date: 2025-09-08T13:49:36 Since I do not have the first domain in the source tenant anymore I need to restore the user to a different domain. Does anyone have any idea on how I can recreate the msol version to mggraph? I feel like I have tried everything to my knowledge now so hopefully anyone here can give me help or tips. Thanks! /Adam
Where can I find a lots of scripts like Script Guy site used to have?
Hi, I am sorry if this is a bit of easy post but the internet appears to be so spread out these days and de-centralised from what it used to be. I am looking for a site that has lots of good scripts similar to the good old Script Guy site. Please can you help. ThanksUnleashing Parallelism in PowerShell
This blog on my site got a lot of possitive feedback. Hopefully it can help others as well hence I share it here. If you want to check more check my blog on: https://bartpasmans.tech/ or check my LinkedIn: https://www.linkedin.com/in/bart-pasmans-6533094b/ Unleashing Parallelism in PowerShell If you’ve been around PowerShell for a while, you know it’s great at looping through stuff. Need to process a list of files? Easy. Query a set of servers? Piece of cake. But sometimes… you hit a wall. The problem? Sequential execution. By default, your loops work in a single-file line, like shoppers at a small-town bakery. That’s fine for five people. Not so fine for five thousand. That’s where ForEach-Object -Parallel enters the chat. 🚀 This feature, introduced in PowerShell 7, lets you process multiple items at the same time, tapping into all those CPU cores just sitting there looking bored. Today, we’re going to walk through how it works, why it’s a game-changer, and where you should (and shouldn’t) use it. We’ll keep it hands-on, so keep PowerShell open! you’ll see the 🎬 icon whenever it’s time to get your hands dirty. Today’s Toolbelt Here’s the deal: ForEach-Object -Parallel is like the express checkout lane at the grocery store. Instead of every task waiting for the one ahead to finish, they all get their own lane. We’ll explore: Basic parallel loops – Using ForEach-Object -Parallel in the simplest form Passing variables – How to get data into your parallel script block Controlling thread counts – Because unlimited parallelism can get… messy Real-world scenarios – Places where it shines (and where it doesn’t) Why Parallel? Imagine you have 50 servers to check for a certain log file. Running them one after another takes… forever. With parallel processing, you can hit multiple servers at once, finishing in a fraction of the time. 📒 Under the hood: PowerShell spins up runspaces, lightweight, isolated environment, to execute each chunk of work simultaneously. It’s not “true” OS-level multithreading, but it’s incredibly efficient for I/O-bound tasks like network calls, file reads, or API requests. 1..5 | ForEach-Object -Parallel { Start-Sleep -Seconds 1 "Task $_ completed on thread $([System.Threading.Thread]::CurrentThread.ManagedThreadId)" } What’s happening: 1..5 gives us five items. Each item is processed in a parallel runspace. They all sleep for one second…. 🥁🥁🥁 but because they run in parallel, the whole thing finishes in just over a second, not five! My previous blog: https://bartpasmans.tech/start-scripting-like-a-pro-6-speeding-up-your-code/ I showed you how to make your own threads and consume them. Check it out! 😊 This blog sticks with PowerShell cmdlets natively. Passing Data Into Parallel Blocks One catch with ForEach-Object -Parallel: it runs in its own scope. Your outer variables aren’t magically available inside. 🎬 Here’s how to pass variables in: $prefix = "Server" 1..3 | ForEach-Object -Parallel { "$using:prefix-$($_)" } 📒 The magic word: $using: tells PowerShell to bring in a variable from outside the parallel block. Controlling the Chaos Yes, parallelism is powerful, but if you let 200 jobs spin up at once, you might as well be starting a tiny CPU apocalypse 💣. 🎬 Throttle it with 1..10 | ForEach-Object -Parallel { Start-Sleep -Seconds 2 "Processed $_" } -ThrottleLimit 3 Here, only three parallel tasks run at a time. As soon as one finishes, the next starts. Real-World Example: Network Ping 🎬 Checking multiple hosts in parallel: $servers = "server1","server2","server3","server4","server5" $servers | ForEach-Object -Parallel { $result = Test-Connection -ComputerName $_ -Count 1 -Quiet "$_ is " + ($(if ($result) { "online" } else { "offline" })) } -ThrottleLimit 2 The pings happen two at a time. Overall time drops drastically compared to running sequentially. When Not to Use It 📒 Parallelism is not a free lunch. If your task is super short and light (like adding numbers), spinning up runspaces is actually slower. For CPU-heavy operations, you might saturate your system quickly. Avoid it when order matters—parallel execution doesn’t guarantee output order unless you take extra steps. Summary Wrapping It Up! PowerShell Meets Parallelism 🎉 Today we saw how ForEach-Object -Parallel lets you take PowerShell’s already-great iteration abilities and put them into warp speed. We covered: The basics of parallel loops Passing variables with $using: Throttling to keep your system happy Real-world use cases like pinging servers The takeaway? When you’re faced with a big list of time-consuming tasks, don’t just wait your turn in the single checkout lane. Open more lanes with ForEach-Object -Parallel! Just remember that more isn’t always better. Got your own clever use for parallel loops? Share it, I love seeing how people bend PowerShell to their will. Until next time! Keep automating, keep experimenting, and keep pushing your scripts to the next level. 🚀☕🍰
Error setting profile for interface Primary LAN Interface
Hi all I have a problem with this script. It says "Error setting profile for interface Primary LAN Interface: The network connection profile is corrupted". I need to set the Network card Protected EAP Properties to "Smartcard or other certificate" and set the Trusted Root Certification Autorities to use our Root certificate.
