Splatting for Better Code, Mr. Rogers' Get-NetNeighborhood
Also, congrats to all the renewed MVPs!
Good morning and happy Monday! Congrats to all the renewed Microsoft MVPs! I saw a comparable meme to the one above on LinkedIn (from an MVP) in response to the flood of posts for everyone who was renewed successfully this year. I am personally so proud to be a part of that community - my physical award actually just came in last week, so I joined in on the posting.

ITProToday has a great video on managing PATH Environment variables.
On last week’s PowerShell Wednesday, Andrew sat down with David Richmond to talk about splatting. Definitely some useful tips - I was able to join this week and learned a little bit more about splatting than I realized. I also updated my PowerShell GPT to generate code with some of David’s tips in mind.
NetITGeeks had an interesting video that shows how to play music and do text speach in PS. This could be a great accessibility feature for those of us making graphical apps.

Copilot Studio Agent Vulnerability to Prompt Injection
Tony Redmond has an interesting article on a recent Copilot Studio agent vulnerability that allowed prompt injection to exfiltrate data, highlighting that while Microsoft implemented a fix, the fundamental challenge of natural language prompt injections means new attack vectors are likely. Not directly PowerShell related, but an interesting read as I’m sure a lot of you are using the Copilot Studio agent.
Supercharge Microsoft Graph API Data Retrieval with PowerShell Batch Requests
Jorge Suarez has a post on how to significantly speed up Microsoft Graph API data retrieval in PowerShell by leveraging batch requests, reducing wait times by up to 88% and providing a robust Invoke-mgBatchRequest function that handles multi-cloud environments, intelligent nextLink processing, and memory management.
