The final PowerShell Weekly of 2025 is here.

If you’re new: PowerShell Weekly is hand-curated every single week of the year. No bots, no auto-aggregation. I read, select, and organize the content so it’s actually worth your time.

Which is what I take two weeks off at the end of the year to recharge and get ready to do 50 editions again next year.

If you’ve been reading, sharing, or contributing this year, thank you. It genuinely makes the effort worthwhile.

Go check out this last issue of 2025, enjoy the holidays, and I’ll see you back here the first week of 2026.

The recent breaking change to Invoke-WebRequest in Windows PowerShell 5.1 has the potential to affect a lot of automation, especially in older environments. To make it easier to assess the impact, I published a script called Search-CmdletParameterUsage.ps1.

This tool recursively scans your scripts and modules for any cmdlet + parameter usage. While I built it to identify places where Invoke-WebRequest is not using -UseBasicParsing, it works generically for any cmdlet you're concerned about.

If you maintain large codebases or inherited automation, this can save a ton of manual review.

Script: https://gist.github.com/mdowst/9d00ff37ea79dcbfb98e6de580cbedbe

KB on the breaking change: https://support.microsoft.com/en-us/topic/powershell-5-1-preventing-script-execution-from-web-content-7cb95559-655e-43fd-a8bd-ceef2406b705

Happy scripting! And good luck hunting down those IWR calls.

Saving Christmas with PowerShell: Building a Reusable Matching Algorithm

This video isn’t just “here’s a script.” It walks step-by-step through the whole evolution of the solution:

• Start with a naive random shuffle
• Add constraints and filtering
• Introduce backtracking when things get messy
• Turn it all into a clean, reusable function

The end result is a robust matching engine you can adapt for scheduling, load balancing, on-call rotations, pairing systems, etc.

• App-Only Authentication for SharePoint Online PowerShell
  The latest versions of the SharePoint Online PowerShell module support app-only authentication (certificate-based authentication) for the Connect-SPOService cmdlet. In other words, applications can now connect to SharePoint Online to run administrative cmdlets by presenting a registered Entra ID app and an X.509 certificate instead of the credentials for a human SharePoint administrator. It’s a good change, even if I still prefer using the Graph APIs for SharePoint automation.
